Row explanation.In two-phase electric rotating machine 30, if the electric current supplied by supply unit 10 is supplied to armature coil 39, at tooth 34
Magnetic flux is generated, and generates polarity or repulsion between the magnetic flux and the rotor magnet 33 of rotor 31, to make rotor 31
Rotation.
However, using rotor magnet 33 of chain segment type, gap is formed between each rotor magnet 33, therefore with
The circumferential direction both ends of rotor magnet 33 are boundary line, and the variation of magnetic flux becomes larger.Therefore, pass through the both ends of rotor magnet 33 in each tooth 34
When, the polarity or repulsion of each tooth 34 are widely varied, to which cogging torque (cogging torque) becomes larger.Cause
And the quantity P of the magnetic pole and quantity S of tooth 34 is set in a manner of meeting formula as shown below (1), thus become low cogging torque
Two-phase electric rotating machine 30.
[numerical expression 1]
Number of teeth amount S=4n
Quantity P=S ± 2 (1) of magnetic pole
Furthermore n is natural number.Wherein, small for the contribution of the attenuating of cogging torque in the case of n≤2.In addition, i.e.
Just the quantity S of the quantity P of magnetic pole and tooth 34 is integral multiple, and formula (1) is also set up.
Hereinafter, becoming low tooth to two-phase electric rotating machine 30 by meeting formula (1) by the quantity P of magnetic pole and the quantity S of tooth 34
The case where slot torque, illustrates.

According to formula (2) and formula (3), rotor magnet 33 and phase difference (electric angle) α of tooth 34 are indicated by formula below (4).
[numerical expression 4]
Phase difference
Herein, 0 ° of angle is set as when if the center of first tooth 34 is consistent with the center of rotor magnet 33, and will be reversed
The amplitude of voltage is set as 1, then synthesizes backward voltage E and indicated by formula below (5).
[numerical expression 5]
E=sin θ+sin (θ-α)+sin (θ -2 α)+... (5)
As shown in formula (5), if phase difference | α | become larger, the section for offsetting backward voltage is elongated, and synthesis backward voltage E becomes
It is low.On the other hand, if phase difference | α | become smaller, the section for offsetting backward voltage shortens, and synthesis backward voltage E is got higher.That is, phase
For potential difference α closer to 0, the efficiency of two-phase electric rotating machine 30 is better.Herein, phase difference α is indicated by formula (4), it is therefore desirable that
The value of (the quantity P of magnetic pole)/(the quantity S of tooth 34) becomes the value close to 1.However, the quantity of the quantity P and tooth 34 when magnetic pole
When S is identical value (P=S), the structure as two-phase electric rotating machine is invalid.In order to make the structure as two-phase electric rotating machine
It sets up, and needs the multiple that the quantity S of tooth 34 is 4, and the multiple that the quantity P of magnetic pole is 2.Thus, pass through two-phase electric rotating machine
30 meet formula (1) and become low cogging torque, and the composition of the electric rotating machine as the good two-phase of efficiency.In 1st embodiment,
The quantity P of magnetic pole is 14, and the quantity S of tooth 34 is 12.

At least one of the powered-on mode #2 of powered-on mode of circuit, powered-on mode #4, powered-on mode #6, powered-on mode #8 is closed to be powered
Pattern.
As described above, the two-phase rotary electric machine controller 40 in the 1st embodiment can flow through A phase coils 30a in switching
With before the direction of the excitation current of any coil in B phase coils 30b the two coils and flow through switching excitation current
After the current reflux of the object coil in direction, the switching control in the direction of excitation current as defined in being switched to is executed.That is, the 1st is real

As a result, when switching flows through the sense of current of A phases or B phases (coil), the generation through electric current can be prevented, and
It can prevent from not generating the torque of electric rotating machine.
Hereinafter, being illustrated to the variation of the two-phase rotary electric machine controller 40 in the 1st embodiment.Fig. 5 is table
Show the switching time point for the powered-on mode that the two-phase rotary electric machine controller 40 of the variation in the 1st embodiment is carried out
The figure of an example.
The two-phase rotary electric machine controller 40 of this variation has powered-on mode #1~energization mould in the 1st embodiment
The powered-on mode that powered-on mode #4 and powered-on mode #8 is omitted in formula #8.
That is, the two-phase rotary electric machine controller 40 of this variation passes through repeatedly with powered-on mode #1, powered-on mode #2, logical
The sequence switching powered-on mode of power mode #3, powered-on mode #5, powered-on mode #6, powered-on mode #7, to rotate driving two-phase
Electric rotating machine 30.As a result, compared with the 1st embodiment, the powered-on mode of the two-phase rotary electric machine controller 40 of this variation
It is few, therefore can realize the simplification of the control for 211~switch element of switch element 216.For example, two-phase electric rotating machine controls
Device 40 is based on respectively by the rise time point of the 1st hole IC and the 2nd hole IC pulse signal H1 supplied and pulse signal H2
Or fall time point (pulse signal H1 and pulse signal H2 the rise time points or fall time point of any one) controls switch
The conducting state and off-state of 211~switch element of element 216.At this point, as shown in figure 5, two-phase rotary electric machine controller
40 at powered-on mode #1, powered-on mode #3, powered-on mode #5, powered-on mode #7, can be in pulse signal H1 and pulse signal H2
The time point risen or fallen conducting state or off-state are controlled to 211~switch element of switch element 216, but be powered
It, can not be in the rising of pulse signal H1 and pulse signal H2 under pattern #2, powered-on mode #4, powered-on mode #6, powered-on mode #8
Or the time point declined controls conducting state or off-state to 211~switch element of switch element 216.Thus, it is being powered certainly
In the case that pattern #1 is switched to powered-on mode #2, time of the two-phase rotary electric machine controller 40 from the rising of pulse signal H1
It lights and is switched to powered-on mode #2 after counting the set time.That is, implement powered-on mode #2, powered-on mode #4, powered-on mode #6,
In the case of powered-on mode #8, two-phase rotary electric machine controller 40 needs to carry out the processing (hereinafter referred to as " meter of gate time
When handle ").Thus, by omitting powered-on mode #4, powered-on mode #8, compared with the 1st embodiment, two-phase rotation can be cut down
The timing of motor control assembly 40 is handled.
Hereinafter, the reasons why pair can omitting powered-on mode #4 and powered-on mode #8, illustrates.
In the case where powered-on mode not via powered-on mode #4 is switched to powered-on mode #5 from powered-on mode #3, not
The closed circuit for the current reflux for flowing through B phase coils 30b is formed, therefore can not lower and be drawn by the self-induction of B phase coils 30b
The influence risen.Similarly, it when powered-on mode is switched to powered-on mode #1 from powered-on mode #7, is not formed and flows through B phase lines
The closed circuit of the current reflux of 30b is enclosed, therefore the influence caused by the self-induction by B phase coils 30b can not be lowered.That is, depositing
During not generating the torque for making the rotation driving of two-phase electric rotating machine 30.
However, in the case of powered-on mode #3,212~switch element of switch element 215 is off-state, therefore by electricity
The electric current that source device 10 supplies is by being connected in series with the path of A phase coils 30a and B phase coils 30b.In the feelings of powered-on mode #7
Under condition, switch element 211, switch element 212, switch element 215, switch element 216 are off-state, therefore by supply unit
Electric currents (excitation current) and the powered-on mode #3 of 10 supplies are likewise by being connected in series with A phase coils 30a and B phase coils 30b
Path.Being connected in series with the resistance in the path of A phase coils 30a and B phase coils 30b becomes the resistance value R of A phase coils 30aa
Resistance value (R made of being added with the resistance value Rb of B phase coils 30ba+Rb).Furthermore in embodiment as shown below, for side
Just for the sake of, and to resistance value RaWith resistance value RbFor identical resistance value RcThe case where illustrate.I.e., it is assumed that A phase coils 30a
It is identical as the inductance of B phase coils 30b.Thus, being connected in series with the resistance in the path of A phase coils 30a and B phase coils 30b becomes
2Re.On the other hand, in powered-on mode #1 or powered-on mode #5, the electric current that is supplied by supply unit 10 by path be to pass through A
The path of any armature coil 39 in phase coil 30a and B phase coils 30b.That is, the electric current supplied by supply unit 10 by
Path is not connected in series with the path of A phase coils 30a and B phase coils 30b, but only via A phase coil 30a or B phase coils
The path of 30b.That is, only becoming R via the resistance in the path of A phase coil 30a or B phase coils 30bc.Thus, it is assumed that power supply fills
In the case of 10 voltage is set as 12V, it is connected in series in the path of A phase coils 30a and B phase coils 30b, to A phase coils 30a
Apply the voltage of 6V respectively with B phase coils 30b.On the other hand, right only via in the path of A phase coil 30a or B phase coils 30b
A phase coil 30a or B phase coils 30b applies the voltage of 12V.It is connected in series with A phase coils 30a and B phase coils 30b's that is, constituting
Powered-on mode #3, the powered-on mode #7 in path and the energization mould for having the path only via A phase coil 30a or B phase coils 30b
Formula #1, powered-on mode #5 are compared, and the electric current for flowing through A phase coil 30a or B phase coils 30b is small.
In general, savings is in the product of the energy and the quadratic sum inductance for the electric current for flowing through the magnetizing coil of magnetizing coil
It is proportional.Thus, with the electric current for flowing through magnetizing coil becomes larger and counter electromotive force is got higher.As a result, with powered-on mode #3, energization mould
Formula 7 is compared, and powered-on mode #1, the savings of powered-on mode #5 are big in the energy of A phase coil 30a and B phase coils 30b.That is, by certainly
Powered-on mode #3, powered-on mode #7 carry out inverse excitatory (powered-on mode #3 → powered-on mode #5, powered-on mode #7 to B phase coils 30b
→ powered-on mode #1) and the counter electromotive force of generation is less than by being carried out from powered-on mode #1, powered-on mode #5 to A phase coils 30a
Inverse excitatory (powered-on mode #1 → powered-on mode #3, powered-on mode #5 → powered-on mode #7) and the counter electromotive force generated.Thus, it closes
(hereinafter referred to as " during torque does not generate "), lead to during by the inverse excitatory torque without generation two-phase electric rotating machine 30
Power mode #1 → powered-on mode #3, powered-on mode #5 → powered-on mode #7 are shorter than powered-on mode #3 → powered-on mode #5, energization mould
Formula #7 → powered-on mode #1.As long as may be allowed powered-on mode #3 → powered-on mode #5, powered-on mode #7 → powered-on mode #1 as a result,
Torque do not generate during, then it is (powered-on mode #1 → powered-on mode #3, logical during long inverse excitatory during torque does not generate
Power mode #5 → powered-on mode #7) in, it is inverse using being carried out after the powered-on mode #2 and powered-on mode #6 for forming closed circuit respectively
It is excitatory, powered-on mode #4 and powered-on mode #8 can be omitted.
Thus, according to the variation, effect identical with the 1st embodiment can be played, and can realize for switch
The simplification of the control of 211~switch element of element 216.
