By arranging in this way, contact between each connecting wire and each pin is prevented.
Moreover, the pin which latches the terminal wire of auxiliary | assistant winding body 12a-12d is also arrange | positioned on the surface opposite to the axial direction from the pin which latches the terminal wire of main winding body 11a-11b.

According to the first embodiment of the present invention, the following effects can be obtained.
First, after winding the winding end line of the reference coil to the pin, the first speed adjustment coil is wound without cutting the winding end line, and even if the number of layers of the speed adjustment coil increases, the pin Therefore, the increase in the number of parts can be suppressed.
Further, since the locking operation of the winding end line of the reference coil and the locking operation of the winding start line of the first speed adjusting coil are integrated into one time, the productivity of the rotating electrical machine can be improved.
Further, since the winding end magnetic pole of the reference coil and the winding start magnetic pole of the first speed adjusting coil are the same, there is no need to perform the operation of making the nozzles face each other twice.
Thereby, the productivity of the rotating electrical machine can be further improved.
In addition, by setting the terminal wire position of the main winding body and the location of the terminal wire of the auxiliary winding body as separate surfaces in the axial direction of the stator, A work space for soldering can be secured sufficiently because it can be arranged on one magnetic pole.
Furthermore, contact between each crossover and each pin is prevented.
This is particularly effective in a small rotating electrical machine having a small stator outer diameter.

In the present embodiment, the method of winding the speed control coil around the main winding body has been described. However, the same effect can be obtained by winding the speed control coil around the auxiliary winding body.
In addition, although the example in which the number of speed adjustment steps is 3 (reference coil + speed adjustment coil 2 layers) is described, the same effect can be obtained even if the number of steps changes.
For example, when the number of speed adjustment stages is two, the lead wire 71 locked to the pin 26c of the main winding body 11c in the state shown in FIG. 6 is cut to form the main winding bodies 11a to 11d. The winding body can be configured by winding a number of turns suitable for the number of turns of the main winding body.

  When the distance from the back side of the connecting portion 51 to the upper end in the axial direction where the tea score 201 is inserted is L2, a relationship of L1 <L2 is established between L1 defined for the insulator 4 and L1.

Next, a method for manufacturing the stator will be described.
FIG. 14A is a perspective view of the main winding body 211 (first winding body).
The main winding body 211 is a conductor in the conductor press-fitting hole 224 with the tee scores 201 half-fitted in the teeth insertion portions 43 provided at four locations of the insulator 4 and the other half covered with the insulator 202.

A stator as shown in FIG. 15A is configured by winding the winding in a space in which the windings of the main winding body 211 and the auxiliary winding body 212 are wound.
In assembling the stator, the yoke core 3 is disposed, the main winding body 211 is disposed from the upper side in the axial direction, and the auxiliary winding body 212 is disposed from the upper side in the axial direction. It can be configured by press-fitting the wire wound body 211 and the auxiliary winding body 212.

At this time, the teeth constituting the main winding body 211 and the teeth constituting the auxiliary winding body 212 are press-fitted in a state of being displaced by 45 degrees in the circumferential direction.
Furthermore, since the relationship between the dimension L1 of the insulator 4 and the dimension L2 of the insulator 5 is L1 <L2, the connecting portion 41 of the insulator 4 and the connecting portion 51 of the insulator 5 do not interfere with each other.
As a result, all the tee scores 201 of the main winding body 211 and the auxiliary winding body 212 and the upper and lower end surfaces in the axial direction of the yoke core 3 can be aligned.

Next, a method for winding the stator will be described.
16 to 19, main coils (reference coil, first speed adjustment coil, second speed adjustment coil) are wound around the four main winding winding portions 211 a to 211 d of the main winding body 211. It is a top view of each main winding part 211a-211d in each process.
FIG. 16 is a plan view showing a state of the main winding parts 211a to 211d before starting the winding of each coil.
As shown in the figure, the main winding body 211 is arranged in an annular shape so as to have substantially the same outer diameter and position as the arrangement of the completed stator.
In the first embodiment, the coils are wound so as to face each main winding body by rotating the nozzle in the circumferential direction of the stator.
In the present embodiment, the main winding winding body 211 and the auxiliary winding winding body 212 are rotated around their respective central axes, whereby the respective windings are mounted on the flyer 208 fixed on the outer peripheral side. The coil is wound with the parts facing each other.

The flyer 208 is provided with an arm portion 282 attached to the shaft end of the pivot shaft 281 around the pivot shaft 281 so as to be pivotable in the forward and reverse directions as indicated by an arrow θ, and in synchronization with the pivot operation. It is configured to slide in the X-axis direction.
Then, the supplied conductive wire 71 is connected from the proximal end side of the arm portion 282 of the flyer 208 to the distal end portion through the inside of the arm portion 282. The main winding body 211 is installed so as to be rotatable in the arrow Y-axis direction. At this time, two conductive pins 226 are inserted into the conductor press-fitting holes 224 of the insulator 202, for a total of eight, and are fixed (see FIG. 15 which is not directly visible because it is on the back side in FIGS. 16 to 19).
In FIG. 17 and subsequent figures, the flyer 208 is omitted for simplification of description.

FIG. 17 is a plan view showing a state immediately after the reference coil 206 is wound around the four main winding portions 211 a to 211 d of the main winding body 211.
First, as a first locking step, the end of the winding start line of the reference coil 206 (hidden from the direction of the figure and not visible) is pin 226a1 (actually on the back side) of the main winding portion 211a. The same shall apply hereinafter).

Next, a first reference coil winding process is performed.
The reference coil 206 a is wound with the flyer 208 facing the main winding portion 211 a of the main winding body 211.
When the winding of the reference coil 206a is finished, the main wire winding body 211 is rotated 90 degrees in the direction of the arrow Y after the crossover wire α is hooked on the crossover wire holding portion 44 of the main winding portion 211a.
Next, the connecting wire α is hooked on the connecting wire holding portion 44 of the main winding winding portion 211b, and the reference coil 206b is wound around the main winding winding portion 211b.
At this time, the connecting wire α is continuously wound without being cut.
Similarly, the reference coil 206c and the reference coil 206d are wound in the order of the main winding portion 211c and the main winding portion 211d.
When the winding of the reference coil 206d is finished, the winding end line of the reference coil 206d (not visible in the direction of this figure) is related to the pin 226d1 of the main winding part 211d as the second locking step. Stop.
Also here, the conducting wire 71 is not cut.

Next, a speed adjusting coil winding process is performed.
FIG. 18 is a plan view showing a state immediately after the first speed adjustment coil 261 is wound around the four main winding portions 211 a to 211 d of the main winding body 211.
Winding of the first speed adjustment coil 261 starts from the main winding part 211d around which the reference coil 206d is finally wound.

Since the flyer 208 is currently facing the main winding portion 211d, the first speed adjusting coil 261d is wound as it is.
When the winding of the first speed adjusting coil 261d is completed, the main winding body 211 is moved 90 degrees in the direction of the arrow Y after the connecting line β is hooked on the connecting wire holding part 44 of the main winding part 211d. Rotate.
Next, the connecting wire β is hooked on the connecting wire holding portion 44 of the main winding winding portion 211a, and the first speed adjusting coil 261a is wound around the main winding winding portion 211a.
At this time, the connecting wire β is continuously wound without being cut.
Similarly, the first speed adjustment coil 261b and the first speed adjustment coil 261c are wound in the order of the main winding portion 211b and the main winding portion 211c.
When the winding of the first speed adjusting coil 261c is finished, as the third locking step, the winding end line of the first speed adjusting coil 261c (hidden from the direction of this figure and cannot be seen) is displayed as the main winding winding part. The pin is fixed to the pin 226c1 of 211c.
Also here, the conducting wire 71 is not cut.

Next, a multi-layer speed adjusting coil winding step is performed.
FIG. 19 is a plan view showing a state immediately after the second speed adjustment coil 262 is wound around the four main winding portions 211 a to 211 d of the main winding body 211.
The winding of the second speed adjustment coil 262 starts from the main winding portion 211c around which the first speed adjustment coil 261c is finally wound.

Since the flyer 208 is currently opposed to the main winding part 211c, the second speed adjustment coil 262c is wound as it is.
When the winding of the second speed adjustment coil 262c is finished, the main winding body 211 is moved 90 degrees in the direction of the arrow Y after the connecting wire γ is hooked on the connecting wire holding part 44 of the main winding part 211c. Rotate.
Next, the crossover wire γ is hooked on the crossover holding portion 44 of the main winding portion 211d, and the second speed adjustment coil 262d is wound around the main winding portion 211d.
At this time, the crossover wire γ is continuously wound without being cut.
Similarly, the second speed adjustment coil 262a and the second speed adjustment coil 262b are wound in the order of the main winding portion 211a and the main winding portion 211b.
When the winding of the second speed adjusting coil 262b is finished, the winding end line of the second speed adjusting coil 262b (invisible from the direction of this figure) is not shown as the fourth locking step. The pin is fixed to the pin 226b1 of 211b.
As described above, the conductor 71 is cut after all the coils are wound on the main winding portions 211a to 211d of the main winding body 211.

Note that the crossover line α, the crossover line β, and the crossover line γ are arranged in the connecting portion 41 of the insulator 4.
Compared with the winding of each coil around the main winding wound body 211, the connecting work to the auxiliary winding wound body 212 is that each crossover is arranged at the connecting portion 51 of the insulator 5, the insulator 4 Since it is the same as the winding method of the reference coil (main coil) of the main winding wound body 211 except that the insulator 5 is used instead, the number of turns of the coil, the winding direction, and the winding order are different. Omitted.

The stator of the motor can be configured by alternately arranging the main winding body 211 and the auxiliary winding body 212 manufactured in this manner in an annular shape as shown in FIG. .
Furthermore, a rotating electrical machine can be configured by inserting a cylindrical rotor having a shaft on the inner peripheral side of the stator.

  In addition, although the example in which the number of speed adjustment steps is 3 (reference coil + speed adjustment coil 2 layers) has been described, the same effect can be obtained even if the number of steps changes. For example, when the number of speed adjustment steps is 2 (reference coil + speed adjustment coil 1 layer), the conductor 71 that is locked to the pin 226c1 of the conductor press-fitting hole of the main winding portion 211c in the state of FIG. 18 is cut. The main winding body 211 can be configured, and the auxiliary winding body 212 can be configured by winding a coil having a number of turns suitable for the number of turns of the coil of the main winding body 211.

  Table 2 shows the relationship between the number of speed adjustment steps of the rotating electrical machine and the number of times that the conducting wire is engaged with the pin of the conductor.

In Patent Document 1, as shown in Table 1, when the number of speed adjustment steps is 4 (reference coil + speed adjustment coil 3 layers), each of teeth No. 1 and teeth No. 4 requires four pins.
In the case of the present embodiment, as shown in Table 2, up to 7 speed adjustment stages (reference coil + speed adjustment coil 6 layers), each winding winding body may have two pins.
The small number of pins means that the conductor press-fitting holes for press-fitting the pins into the insulator may be small, and it is not necessary to provide the conductor press-fitting holes in the space for winding.

  Further, the locking operation of the winding end line of the main coil and the locking operation of the winding start line of the first speed control coil (the winding end line of the first speed control coil and the winding start line of the second speed control coil, etc. Since the winding end line of the second speed coil and the third winding coil winding start line, etc. are all combined in one time, the number of times of the four-speed locking in Patent Document 1 and the speed control 7 according to the present embodiment are as follows. The number of locking steps can be the same (eight times). For this reason, it is possible to suppress a decrease in productivity even if the number of speed adjustment steps increases.

According to the rotating electrical machine according to the second embodiment of the present invention, since the magnetic pole is divided into the tee score 201 and the yoke core 3, a winding device (nozzle or flyer) is provided on the inner peripheral side of each tooth as in the first embodiment. There is no need to place them.
Thereby, even in the case of a product having a small inner diameter of the rotating electrical machine, it is not necessary to downsize the winding device, and a normal winding device can be used.

In addition, after the winding end line of the reference coil is locked to the pin, the first speed adjustment coil is wound without cutting the winding end line, so the number of layers of the speed adjustment coil increases. Also, the number of pins can be suppressed, and the number of parts can be reduced.
Further, since the anchoring operation of the winding end line of the reference coil and the anchoring operation of the winding start line of the first speed adjusting coil can be consolidated at one time, the productivity of the rotating electrical machine can be improved.

Further, since the magnetic pole at the end of winding of the reference coil and the winding start magnetic pole of the first speed adjusting coil are the same, there is no need to perform the operation of making the flyer face again. This can further improve productivity.
Furthermore, the fact that the number of pins used is small can reduce the conductor press-fitting holes for press-fitting the pins into the insulator, and the winding space can be expanded.
Thereby, a desired torque can be obtained in a small space, and an increase in the size of the rotating electrical machine and an increase in materials used can be suppressed.

Further, as shown in FIG. 15 (b), there are a connecting portion 41 where the connecting wire of the main winding body 211 is arranged and a connecting portion 51 where the connecting wire of the auxiliary winding body 212 is arranged. The position is shifted in the axial direction of the stator, and the space is separated by a connecting portion of insulators 4 and 5 which are insulators. For this reason, it is possible to prevent the connecting wires of the main winding body 211 and the connecting wires of the auxiliary winding body 212 from coming into contact with each other, and insulation can be easily performed.

In addition, each of the connecting wires α, β, γ can be arranged at a position far from the pin press-fitted into the conductor press-fitting hole in the radial direction of the stator. Can be easily prevented.
In addition, since the main winding body 211 and the auxiliary winding body 212 are held by the insulator 4 and the insulator 5 to which the tooth insertion portions are connected, the main winding winding body is disassembled as in the first embodiment. Compared with the case where a plurality of bodies and auxiliary winding bodies are carried, handling properties are improved, and conveyance during production is simplified.

  Moreover, even if it arrange | positions a winding apparatus from the outer peripheral side of a stator (teascore) by arrange | positioning the connecting wire (alpha), (beta), and (gamma) in the connection part of the inner peripheral side of teeth, the flyer 208 and the connecting wire (alpha), There is no interference with β and γ, and it is possible to suppress the deterioration of the insulating film of the crossover wires α, β, and γ.

  Further, each main winding winding part and each auxiliary winding winding part are arranged in an annular shape so that the main winding winding body 211 and the auxiliary winding winding body 212 are configured. The operation of making the auxiliary winding winding part and the auxiliary winding winding part face the flyer 208 only needs to be rotated, the work can be performed at high speed, and the equipment for winding can be simplified.

  Moreover, each main winding part of the main winding body 211 that winds a plurality of speed control coils, and each auxiliary winding part of the auxiliary winding body 212 that does not wind a speed control coil Can be arranged in an annular shape so that they have the same outer diameter and position as the stator when they are configured separately, and can be combined as they are to form the stator. Productivity.

Further, the flange portion provided at the connecting portion for arranging the crossover can prevent the crossover from entering the rotor, and can prevent contact between the rotor and the crossover.
Furthermore, since the inner diameter of the connecting portion is larger than the outer diameter of the rotor, the rotor can be inserted into and removed from both sides of the stator in the axial direction.
Thereby, the freedom degree in the manufacturing process of a rotary electric machine increases.

After the winding end line of the reference phase coil is locked to the pin, the first speed phase adjustment coil is wound without cutting the winding end line, so the number of speed phase adjustment coils increases. Also, the number of pins can be suppressed, and an increase in the number of parts can be suppressed.
In addition, since the locking operation of the winding end line of the reference phase coil and the locking operation of the winding start line of the first speed phase adjusting coil are consolidated at one time, productivity can be improved.
Moreover, since the magnetic pole at the end of winding of the reference phase coil and the magnetic pole at the beginning of winding of the first speed phase adjusting coil are the same, there is no need to perform the operation of making the nozzles face again.
