CONSTITUTION:When an electric switch 7a is closed, a capacitor 26a is charged through a resistor, and as the voltage rises, the base current of a transistor 25b is gradually increased, and the base current of a transistor 25a is gradually increased. When the capacitor 26b is charged to the set voltage, a trigger diode 27 is conducted, an output electric pulse is inputted to a ring counter 40, and the positive voltage is outputted to the output terminal 40a. Then, positive voltage is outputted sequentially cyclically to the output terminals 40b, 40c,... of the counter 40, and as the charging of the capacitor 26 is advanced at this time, the switching of the outputs of the output terminals 40a, 40b,... is accelerated. These outputs are applied to an armature current distributor.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a semiconductor motor that controls an armature current using a position detection electric signal of phase 1 to drive a multi-phase motor such as 2-phase or 3-phase.

It is well known that a semiconductor motor requires position detection electrical signals of multiple phases corresponding to the number of phases of the armature coil. Furthermore, the Stellar Pink electric motor is characterized in that it does not require the above-mentioned position detection signal and can obtain continuous rotational torque.

In the former case, although it has the advantage of having a large rotational torque and good efficiency, it has the disadvantage of being complicated and expensive. In particular, the use of a position sensing element such as a Hall element has the disadvantage that it cannot be used when the temperature rises.

The latter case has the advantage of simplifying the structure, but on the other hand, it has the serious drawback that a reverse torque is mixed in each step due to the input electric signal, which significantly degrades efficiency. It also has the disadvantage of generating vibrations.

In the former case, several methods have already been developed to obtain drive torque using a one-phase position detection signal, but all of them suffer from deterioration of efficiency, reduction of drive torque, and problems with starting torque. Due to its drawbacks, it is currently limited to special applications such as fan motors.

The device of the present invention is characterized in that it has a novel configuration that eliminates the above-mentioned drawbacks and preserves only the advantages. Next, the details will be explained one by one for each example.

What is shown in FIG. 1 is one of the armature current distribution circuits of the armature coils 2a, 2b, 2c of a well-known three-phase semicircular motor.
This is an example.

In Fig. 1, the symbols EXF, , G are three-phase position sensing devices, and for example, the back electromotive force obtained from the three-phase armature coil is shaped into a rectangular wave by a shaping circuit. This is output from the output terminal 1.2.3, and this is the second
In the time chart shown in the figure, the electric signals 8a,
8b and 9a, 9b and 10a, 10b. These maintain a phase difference of 120 electrical degrees with each other.

The position sensing device can also obtain the above-mentioned electrical signals by other known means.

The outputs of terminals 1.2.3 are inverting circuits 4a, 4b, 4C'
As shown in the figure, the signals are input to AND circuits 5a-, 5'', . . . 5f, with or without intervening.

Therefore, the output of the AND circuit 5a becomes like the electric signals 11a and 11b in the time chart of FIG.
is 120 degrees in electrical angle. The interval between pulses is 240
degree. From now on, all the above-mentioned angles will be displayed in electrical angles.

The outputs of the other AND circuits 5b, 5c, 5d, 5e, and 5f are electrical signals 12a and 12a, respectively, in the time chart of FIG.
12b and 13a and 14a, 14b and 15a, 15
b and 16a, , 16b.

By the action of inverting circuits 4dJ4e and 4f, AND circuit 5
a% Only when outputs of 5b and 5c are present, inverting circuit 4d
, 4e, 4f, the transistors 6a, 6b, 6c are respectively conductive, and the transistors 6d, 6e, 6f are respectively conductive only while the AND circuits 5d, 5e, 5f are outputting. Symbol 7 is a positive voltage terminal.

Therefore, the armature coils 2a, 2J 2c are controlled to be energized in exactly the same way as in the case of Y-type wiring in a commutator motor, and drive torque is generated to rotate them. Armature coil 2
The same effect can be obtained by connecting a82b and 2c with a Δ connection and energizing them in the same way. Although the armature coil energization control circuit described above is for a three-phase motor, the armature coil energization control can be performed using a similar well-known control circuit in the case of a two-phase motor as well. This case will be discussed later.

As can be understood from the time chart in FIG.
The starting point on the left side of the electric signals 8a and 8b is the point where the field magnetic field is zero, so there is no output torque and no back electromotive force, so there is no excessive armature current. This causes copper losses to increase and efficiency to deteriorate. A motor with a large output will further increase this drawback.

In order to eliminate the above-mentioned drawbacks, the electrical signals 11a1 and 11b are generally set to points shifted by 30 degrees as indicated by the arrows, using a logical operation circuit. Other electrical signals 12a, 1
．． 2b and 13a and 14a, , 14b and 15a81
The situation is exactly the same for 5b, 16a, and 16b.

Then, in FIG. 4, when the electric switch 7a is closed, the content 26a is charged through the resistor, and with the rise of its voltage, the base current of the transistor 25b increases gradually, and therefore the pace current of the transistor 25a also increases. Increase gradually.

When the capacitor 26b is charged to the set voltage, the tri-force diode 27 becomes conductive and discharged, and the output electric pulse due to this discharge current is input to the ring counter 40 since the analog switch 29 is blinded. . Therefore, a positive voltage is output to the output terminal 40a.

When the static capacitor 26b is charged, it is discharged via the trigger diode 27, so the analog switch 2
9, a ring counter 40 receives an electric power off signal. Therefore, the positive output of terminal 4 (Ja
b is converted into a positive output. Thus, sequentially output terminal 4
The positive outputs of 0a, 40b, ...... are IIU
Then they take turns and continue cyclically.

As the capacitor 26a is charged, the collector current of the transistor 25a gradually increases, causing oscillation.

The outputs of the output terminals 4Ua, 40b, and PA of the ring counter 40 are inputted to the terminals 21a, 21b, . . . in FIG. 3, respectively.

In FIG. 3, when there is a positive input from the terminal 21a, the output of the OR circuit 22a conducts the transistor 6a via the inverting circuit, and the output of the OR circuit 22e makes the transistor 6a conductive.
The transistor 6e becomes conductive. Therefore, the armature coils 2a and 2b connected in a Y-shape are energized. This fact corresponds to the energization of the armature coils 2a, 2b with the same symbols in FIG. 1, and in the time chart of FIG. 2, the electric signals 11a, ! = 15a In contrast, the energization control of the armature coil is performed from K.

When the terminal 40b in FIG. 4 is converted to a positive output, an input is obtained from the terminal 2i b in FIG. 3, so the OR circuit 22
Transistor 6a becomes conductive via the output of a, and transistor 6f becomes conductive via the OR circuit 22f.

Therefore, armature coils 2a, 2c are energized. This fact corresponds to the energization of the armature coils 2a and 2c with the same symbol in FIG. 1, so the electric signal 1 in the time chart in FIG.
1a and 16a control the energization of the armature coil.1. respond to things.

Under exactly the same circumstances, terminals 40 c and 40 d in Figure 4
, 40e, 40f alternate positive outputs, the OR circuit 22b.

22f and the armature coil (2b,
2c)-+(2a,, 2b)-+(2c, 2a)-+(
2b2C) are sequentially energized. This fact means that the transistors (6b, 6f)→(6b,,6d)−+
(6c, 6d) → (5c, 5e) Corresponds to conduction. Therefore, in the time chart of Figure 2, Denki I S (
12a, 16a)-+ (12a, , 14a)-+ (
14aX13a)→(13a, 15b) corresponds to the energization of the armature coil. Therefore, the rotor rotates in a predetermined direction as a three-phase stainless steel motor.

As mentioned above, depending on the output torque and load, the fourth
Since the frequency of the oscillation circuit shown in the figure is increased by 1llil+, smooth startup can be performed. When the rotation speed reaches about 300 revolutions per minute, the voltage of the capacitor 26a in FIG. 4 becomes equal to the preset reference voltage terminal 24a, so the output of the comparator circuit 24 changes to a high level. Therefore, the analog switch 29 is opened, and the analog switch 29a controlled via the inverting circuit 30a is closed, so that the input at the terminal 28 causes the ring analog switch 29.29a to be closed.
Instead of switching, the same objective can be achieved by using a rotational speed detection device 'f:1' and converting the output to a high level when the rotational speed exceeds a set value. Note symbol 3
0 is an inverted 1'' path, and its positive output closes the analog switch 29. Next, the input signal of the terminal 28 will be explained.

In the time chart of Fig. 2, electric signals (8a, 8
b), (9a, 9b), (ioa, , Job), and if we make them positive pulses, we get the ones shown in symbols 17a and 17b, and between them 15+'? is 60 degrees.

Next, a square wave electric signal 18 is generated by the Flinob Flonf circuit.
a, 18b, can be obtained. When these electric signals are passed through an integrating circuit consisting of 011 (011), a voltage waveform shown by symbol 19 can be obtained. This electric signal is passed through a window comparator to 19a.

19b1 If you get an electric pulse at the cross point, not shown as...
Electric pulse signals 20a, 2ob, . . . are swallowed. Kauke, ``L2j? Low l yun 3 IJ L rise t po 31v.

The 1-way, , L, and S lus widths are the same, but the phase is delayed by 30 degrees.

As mentioned above, the electrical signals (lla, 1lb), (12
a, 12b), (13a), (14a, 14b),
(15a, 15b), (16a, 16b) are caught in the electric signal shifted 30 degrees to the right as shown by the arrow, and the driving torque is obtained using the transistors 6as6b, . . . in Fig. 1. The electric pulse signal 2

f)-+ (6L 6b)→, exactly the same energization control of the armature coil is performed, and a driving torque in one direction can be obtained to constitute a rotating semiconductor motor.

Therefore, from the terminal 28 in FIG. 4, the electric pulse 2 in FIG.
If 0a, 20J, .

Due to the position detection method of the three-phase position detection device, the drive type is exactly the same as that of the electric motor that controls the energization of the Y-type armature coil, which has the effect of improving both output torque and efficiency.

Next, in the apparatus of the present invention, % [pulse signal 2
Regarding the specific means of obtaining 0a, 20b,...
This will be explained with reference to the diagram.

In FIG. 3, the inputs of electric circuits A, B, and C are both terminals of armature coils 2a, 2b, and 2c, respectively. The electric circuits AXB and AXC include window comparators having exactly the same configuration, and their output pulses are outputted from the terminal 23a via the OR circuit 23. Electric circuit A
The details will be explained with reference to FIG.

In Fig. m7 (a), a positive voltage is applied to the non-inverting terminal of the operational amplifier 58a, and a positive voltage is applied to the inverting terminal of the operational amplifier 58b.
Negative voltage is input. Symbol 57 is a standard voltage terminal.

The input voltage of the terminal 55 is the back electromotive force of the armature coil 2a via the operational amplifier 58.

In FIG. 7(b), symbol 61b represents the operational amplifier 58
The input voltage at the non-inverting terminal of a, symbol 61a, is the input voltage at the inverting terminal of the operational amplifier 58b. The symbol 61 is the ground level, and the symbol 62 is the one that crosses the ground level voltage 61 at a point corresponding to the position on both sides of the electric signals 8a and 13b in FIG. 2 when the magnetic field is zero. Therefore, the output of the AND circuit 59a is as shown by the electric pulse 63 in FIG. This electric pulse is transmitted through the OR circuit 23 (
Through the flimp flop circuit (JK type)
60 is input.

The back electromotive force due to other armature fills 2b and 2c is also (a)
It is converted into an electric pulse by the same window comparator as la, and is input through terminal 23B%23C.

Therefore, the output pulses of the OR circuit 23 are equivalent to the electrical pulses 17a, 17J, . . . in FIG.

Therefore, the output of the 717717071 circuit 60 is equivalent to the output of the electronic circuit 18a118b1, . . . in FIG.

When the width of the electric pulse 63 in FIG. 7 is too wide, it is preferable to narrow it by known means.

Since the resistor 61a1 and capacitor 61b in FIG. 7(a) form an integrating circuit, the output thereof is the curve 19 in FIG.
will be the same as

The operational amplifier bδc, 58d1 and time t%59b constitutes a window comparator, so its output is
These are equivalent to the electric pulses 2Qa, 20b, . . . in FIG. 3.

- Connect the output of terminal 5'JC to terminal 28 in Figure 4.
As mentioned above, by inputting , the motor can be rotated as a three-phase DC motor. In the case of a large output, SCR can be used for the transistors 6a%, 6b%, . . . Also, at this time, if the McQuint rotor uses electromagnets instead of permanent magnets, the output torque can be increased.

What is shown in FIG. 8 is a case where the present invention is implemented in a two-phase armature coil.

Fig. 5(b) Id, 2-phase armature coil /' (47a
, 47c) and (47b, 47d).

The armature is fixed to the main body, and the magnet rotor 42 has four
It is provided with poles N and s, and rotates in the direction of arrow H.

The tilt child coil 47 a % 47 c Vi may be one coil and may be divided into two coils by its intermediate tap. Each coil is energized in only one direction,
The Fleming force drives the Maknent rotor 42 in the H direction. The situation is exactly the same for the armature coils 47b and 47d, which are energized with a phase difference of 90 degrees.

The side diagonal circuit shown in FIG. 8 is the armature coil energization control circuit described above. Armature coil 47a, 4'7b
47c and 4nd are transistors 66a, respectively.
,, 66b55c, 66d are connected, and the armature coil 47a%4'7'c and the two silk circuits 47b, 47d are connected in series between the power supply positive electrode 7 and the ground.

When the input electric pulse of the oscillation circuit of FIG. 4(a), that is, the analog switch 29.2!4a is inputted from the terminal 64, a positive output is obtained from the terminal 69a, so the OR circuits 68a and 68b are valved. , transistor 66a366
b becomes conductive, and the armature coils 47a, 4711 are energized.

The next input electrical pulse to terminal 64 causes terminal 69
Since b is converted to a positive output, OR circuit 68b168c
Transistor 66J6[jc is made conductive through , and armature coils 47b and 47c are energized. Next terminal 64
An electric pulse input to terminal 64 converts the lower terminal to a zero output, and a human electric pulse to the next terminal 64 converts the lower terminal to a positive output, so OR times 1m68c, 68d and OR times 1m68c, 68d and circuit 68d, boa
The transistors 66 c and 66 d and the transistors 66 d and 66 a become conductive through the transistors 66 c and 66 d. Therefore, armature coils 47c, 47d and armature coils 4γd, 47a
will be marketed one after another. Moreover, since the frequency of such cyclic energization control is equal to r'j, it is activated as a four-step electric motor.

When the rotational speed reaches the set value, the analog switch 29, 29a in FIG. 4(a) is switched, and the output from the terminal 65 in FIG. 8 is input to the f2jM element 28. Next, the output of terminal 6:0) will be explained.

The induced outputs of both terminals of the armature coils 4''jc and 4'7d are transmitted through diodes and operational amplifiers 65a and 65b,
It is input to the differentiation circuit 65b. Song iTh'+49 a, 49 b and curve 4 of the time chart in Figure 6
9 c z 49d are armature coils 4'/c, respectively.
, 47d and the outputs of the operational amplifiers 65a and 65b are respectively the curves 51a and 5ib and the curves &51 C%.
51 d.

The electric circuit 65b in FIG. 8 is a circuit including a differentiating circuit and an inverting amplification circuit, and the output of the differentiating circuit is the electric pulse 52 a -, 52 b % . . . in the time chart of FIG. 6.
. . . and electric pulses 53a, 53b, . . . are displayed.

Electric pulses 52b, 53b,...
. . . are inverted and become electric pulse trains with the same symbol at the bottom of the time chart. The electric pulse train outputted from the terminal 65 is inputted to the output counter 69 via the terminal 64 via the terminal 28 by switching the analog switch 29, 29a shown in FIG. 4(a).

Therefore, the armature coil is (4'i a, 4"7
b ) → (47b, 4'/'c) → (47c, 47
d)-)(47d, 47a)→The energization is cyclically switched, and the motor is driven as a two-phase DC motor.

As shown in Fig. 8, the armature 4/l/47aS
47c and armature coils 47b% and 47d are connected in series to the power supply, so when the former's back electromotive force is at its maximum value, the latter's back electromotive force becomes weaker, and these are added together to create a reverse Since it is related to the electromotive force, an excessive armature current is not passed even at zero magnetic field, which has the effect of improving efficiency.

Although the output at terminal 65 is stronger than the back emf of the armature coil, such an electrical pulse train can be obtained by other means. Next, I will explain it.

A magnet 45 magnetized to the N1 S pole is fixed to the armature, and the S pole faces the magnetic pole of the magnet rotor 42.

Therefore, the central portion of the north pole of the magnetic rotor 4z is stopped and held at a position facing the central portion of the armature coil 47a. At this time, the light transmitted through the hole 43a is received by the light receiving element 44, and a position detection signal is obtained.

The above-mentioned position detection means may be of any known type, but one example is shown in FIG. 4(b).

In FIG. 4(b), light projected from the direction of the arrow (a light emitting diode is used) passes through the holes 43a%4:ib, . . . in FIG. 4(b). , light receiving element 4
4, and its output is obtained from terminal 41 as a voltage pulse. Figure 5 (
It is also possible to use the rotor 42a of C). That is, a rotor 42 made of a mild steel plate rotates in synchronization with the magnetic rotor 42.
A is provided, and holes 43a, 43b, . . .
Notches 42b, 42c1, . . . corresponding to the above are provided. A coil 53a of about 10 turns is fixed to the main body and is connected to the Hartley or Kolpin oscillation circuit 53, facing the notch 42J4:<c,... . The output of the oscillation circuit 53 is several megacycles, but the notch 42b in the coil 53a
＼42c1 ・・・・It is only performed when they are facing each other,
When facing other parts of the rotor 42a made of mild steel plate, oscillation stops due to iron loss and eddy current loss. Therefore, by rectifying and shaping the output of the terminal 53b, a position detection signal that can achieve the same purpose as the holes 43a, 43b, . . . described above can be obtained. In this case,
Since the output of terminal 53a is high frequency, armature coil 4
It has the advantage that it can be superimposed on the wiring of 7a147b1 town and sent out to the outside.

There are two methods of starting the non-embodiment as described below.

The first means, as in the previous embodiment, is the output of the oscillation circuit whose oscillation frequency gradually increases, and the armature coils 47a, 47b.
,... When the current is applied and the motor is driven as a stainless pink motor, and the specified rotation speed is reached, the link counter 6
9. By switching the input of (Fig. 8) and inputting the position detection signal obtained from rotor 43 or 42a (Fig. 5) to ring counter 69, the system can be operated as a two-phase DC motor. It is something.

As another means, red sea bream shown in FIG. 5(b),
4b) Specify the stop position of the Macrotron rotor 4z and set it so that when the power is turned on, there will be a positive output from the output terminal 69 a j p of the ring counter 69 in Fig. 8. Then, the armature coil 47as47'b is energized, so the magnetic rotor 42 starts in the direction of arrow H, and thereafter the position detection signal (rotor 43, 42a) input to the terminal 64 (FIG. 8) is activated. A continuous drive torque is obtained by the motor, and the motor is operated as a DC motor. In the above case, it goes without saying that the circuits after the operational amplifiers 65a and 65b in FIG. 8 are unnecessary.

It is also possible to remove the magnet 4b and adopt the following means instead. That is, in FIG. 9, the symbol 70 is
9 shows the electric circuit shown in FIG. 8. However, as described above, the circuits after the operational amplifiers 65a and 65b are removed. Transistors 66a, 66b1・
... are maintained in a non-conductive state, so even if the electric switch 2 is closed, the armature current is not applied.

When the electric switch 2 is closed, an input pulse is obtained to the monostable circuit 71 via the capacitor "1.I-", and a positive output is output from the terminal 7ia, and this output is connected to the terminal 6b in FIG. Since the input signal is input, the transistor 66a becomes conductive and the armature coil 47a is energized.Therefore, the magnetic rotor 42 rotates to the left or right, and the armature coil 4'7a rotates to the center. is the magnetic rotor 42
It stops at a point opposite to the center of the north pole.

In this case, in order to avoid stopping at the zero torque position opposite to the S pole, a piece of mild steel is fixed to the armature, and a coggin can be used to avoid stopping at the zero torque position. .

In the case of a salient pole armature, the above-mentioned stopping point can be more reliably stopped at a point opposite to Nh.

The stopping point mentioned below is the same as the stopping point according to Madai-nt 45.

After a few seconds, the output of terminal 71 becomes ground level, so
Transistor 73 becomes conductive, energizing light emitting diode 74. Alternatively, a voltage is applied to the aforementioned Colpison or Hartley oscillation circuit to enable it to operate. Therefore, a position detection signal from the rotor 43 or 42a is obtained, and the motor is continuously driven as a DC motor.

The means described with reference to FIGS. 5(b) and 5(c) can be applied in exactly the same way to the case of a three-phase electric motor. The details will be explained below.

FIG. 5(a) is a developed view of the V unit, the rotor 42, and the electric go coil. Each armature coil of the same phase is connected in series.

The maqui-nod rotor 42 has four NX S poles,
The rotor 43, which rotates synchronously with this, has an equal pinch,
Holes 43a, 43b1, . . . are provided at intervals of 60 m]. The apparatus shown in FIG. 4(b) is similar to the previous embodiment in that position detection outputs corresponding to the positions of the holes 43a, 43b1, . . . are obtained from the light receiving element 44.

Similarly, when the oscillation circuit shown in FIG. 4(a) is activated when the power is turned on, it is driven as a stamping motor. When the set rotational speed is reached and the analog switch 29.29a in FIG. 4(a) is switched, the terminal 28
The above-mentioned position detection signal is input, but since this signal is completely equivalent to the output signal pulse of the terminal 59c in FIG. 7(a), the armature current is subsequently controlled.
It has the characteristic of being serially operated as a DC motor.

When the McNent rotor 45 is fixed to the armature in the position shown, the McNent rotor 42 will move three degrees to the left,
The S pole 1 of the Mac client 4b is stopped at a point opposite to the N pole of the Mac client rotor.

At this time, when the power switch is turned on, the image shown in Fig. 4 (a) appears.
Since the output of the terminal 41 in FIG. 4(b) is directly input to the input terminal of the ring counter 40, the output terminal 40a of the ring counter 40 is converted to a positive voltage and activated. The link counter 40 may be configured so that the output from the terminal 40a is automatically generated when the power is turned on.

By energizing the armature coils 2a and 2b, the magnetic throat rotor 42 is raised in the direction of arrow H. It is clear that the position sensing circuit which is input thereafter is subsequently co-inverted as a /ζ DC motor.

At this time, the oscillation circuit in FIG. 4(a) and the analog switch 29.2! -Ja is to be removed.

In this embodiment, any type of three-phase motor, Y-type or Δ-type, can be used. In the previous embodiment, the induction output when the armature coil is not energized is used as the position detection output, so it is effective only for the Y type.

It is also obvious that the position detection device shown in FIG. 5(C) can be employed.

Similar to the embodiment described in FIG. 5(b), the armature coil 2a is energized to specify the starting position of the maqui-nod rotor 42, and the link counter 40 (FIG. 4(a)) It is clear that it is also possible to employ means for activating the position sensing device to operate it as a DC motor.

As understood from the description of each of the embodiments above, according to the present invention, the objects and effects described at the beginning can be achieved.
