In the present invention, as shown in Figure 7, yoke union body 21Y is set as the straight core state that linearity has roughly launched, and implements coiling.Fig. 7 A is the top view of yoke union body 21Y, and Fig. 7 B is the front view of observing from flank, and Fig. 7 C is a upward view.In addition, the coiling example of Fig. 7, be shown in Fig. 1 and Fig. 2 A like that with respect to the be connected in series situation of deceleration winding WR of main winding WM, among the figure, main winding WM represents that with solid line auxiliary winding WA dots, deceleration winding WR represents with double dot dash line.
At first, with reference to Fig. 7 A, be top side tooth, from T1 to T3, T5, T7, T9, T11 be with one section the mode of reeling every the tooth main winding WM (WM1～WM6) that reels a succession ofly with the tooth T1 of odd number.At this moment, the overlap joint line of main winding WM is by between guide plate 34a, the 34b (with reference to Fig. 5) on the even number part 33 that is formed at top insulator 31.
Secondly, with main winding WM similarly, in the scope of odd number tooth T1, T3, T5, T7, T9, T11 with one section the mode of reeling every a tooth reel a succession ofly deceleration winding WR (WR1～WR6), but this is wound with two kinds of methods.
Be explained according to Fig. 8.Fig. 8 A is the schematic diagram of the tooth that comprises on the above-mentioned yoke union body 21Y of expression, and Fig. 8 B is the key diagram of the 1st kind of method for winding of expression deceleration winding WR, and Fig. 8 C is the key diagram of the 2nd kind of method for winding of expression deceleration winding WR.Wherein, the direction of winding of deceleration winding WR is to make magnetic flux produce along the direction identical with the magnetic flux that is produced by main winding WM.
At first, the 1st kind of method for winding according to Fig. 8 B, on end side tooth T11 after the coiling main winding WM6, the pin of not shown coil winding machine is directly turned back, from end side tooth T11 to T9, T7, T5, T3 until top side tooth T1, with one section the mode of reeling every the tooth deceleration winding WR1～WR6 that reels a succession ofly.In this case, electric current flows to the direction opposite with main winding WM, so coiling direction is opposite with main winding WM.
Secondly, the 2nd kind of method for winding according to Fig. 8 C, on end side tooth T11 after the coiling main winding WM6, make above-mentioned pin return top side tooth T1, from top side tooth T1 to T3, T5, T7, T9 until end side tooth T11, with one section the mode of reeling every the tooth deceleration winding WR1～WR6 that reels a succession ofly.In this case, electric current flows to the direction identical with main winding WM, so coiling direction is identical with main winding WM.What Fig. 7 represented is the 2nd kind of method for winding.The 1st kind of method for winding only put upside down the deceleration winding WR of Fig. 7.
At this, if establishing the terminal of drawing from top side tooth T1 of main winding WM is G, the terminal of drawing from end side tooth T11 is B, if the terminal of drawing from top side tooth T1 of deceleration winding WR is A, the terminal of drawing from end side tooth T11 is F, then shown in Fig. 2 A, the terminal B of main winding WM commonly is connected with the terminal F of deceleration winding WR, so, if the 1st kind of method for winding according to Fig. 8 B, then the potential difference between the main winding WM1 at top side tooth T1 place and the deceleration winding WR6 is very big, so need clamp insulating trip etc. between these windings.
Relative therewith, if the 2nd kind of method for winding according to Fig. 8 C, then the potential difference between the main winding WM1 at top side tooth T1 place and the deceleration winding WR6 reduces, so do not need as above-mentioned the 1st kind of method for winding, to carry out insulation processing, on this meaning, it is comparatively desirable to make above-mentioned pin return the 2nd kind of method for winding of coiling deceleration winding WR behind the top side tooth T1.In addition, in either case, the overlap joint line of deceleration winding WR all and main winding similarly by between guide plate 34a, the 34b of top insulator 31.

Then, draw the terminal E of auxiliary winding WA from top side tooth T2, and draw the terminal D of auxiliary winding WA from end side tooth T12, two ends with yoke union body 21Y link to each other and work yoke 21 circlewise afterwards, with each terminal A～F wiring like that shown in Fig. 2 A, afterwards, by molded and shaped and yoke member 21a～211 are consolidated into one.Wherein, wiring and molded and shaped order can be any.
Below, according to Fig. 9 the example that deceleration winding WR is wound on auxiliary winding WA side is described.Fig. 9 A is the vertical view of yoke union body 21Y, and Fig. 9 B is the front view of observing from flank, and Fig. 9 C is a upward view.
In this case, (WM1～WM6) similarly reels with Fig. 7 A and gets final product main winding WM.Auxiliary winding WA (WA1～WA6), shown in Fig. 9 C, with even number tooth T2 as top side tooth, from T2 to T4, T6, T8, T10, T12 reel in one section the mode of reeling every a tooth a succession ofly.And main winding WM, auxiliary winding WA pass through the guide plate of top insulator 31, lower isolator 32 respectively.
Thereafter, with auxiliary winding WA similarly, with deceleration winding WR (WR1～WR6) be wound on the even number tooth with the direction identical with auxiliary winding WA, but in this case, also preferably as the front illustrates with Fig. 8 C, on end side tooth T12, reel after the auxiliary winding WA6, make the pin of not shown coil winding machine turn back to after the top side tooth T2 coiling deceleration winding WR1～WR6.In this case, deceleration winding WR and auxiliary winding WA similarly pass through the guide plate of lower isolator 32.
If the terminal of drawing from top side tooth T2 of deceleration winding WR is A, the terminal of drawing from end side T is F, terminal D, the E of terminal G, the B of main winding WM, auxiliary winding WA and terminal F, the A of deceleration winding WR, wiring as the equivalent electric circuit of Fig. 2 B, usually the variable-ratio switch SW is selected terminal F the time, then select terminal A when slowing down, deceleration winding WR is connected in series with respect to auxiliary winding WA.
Promptly, in the equivalent electric circuit of Fig. 2 A, Fig. 2 B, if select terminal A by the variable-ratio switch SW, then in Fig. 2 A, deceleration winding WR is connected in series with respect to main winding WM, in Fig. 2 B, deceleration winding WR is connected in series with respect to auxiliary winding WA, thus put on the voltage reduction on main winding WM or the auxiliary winding WA, and the phase angle becomes big, torque reduces thus, realizes the rotation of slowing down.
In addition, in the present invention, be also included within the situation of the deceleration winding WR that all reels on main winding WM and the auxiliary winding WA.Its method for winding gets final product Fig. 7 and Fig. 9 combination, so detailed has illustrated its equivalent electric circuit among Fig. 2 C.That is wiring in the following manner in this case: shown in Fig. 2 C, with respect to the deceleration winding WRa that main winding WM uses, further the deceleration winding WRb that winding WA uses is assisted in series connection.
Thus, by select the deceleration winding by the variable-ratio switch SW, in the deceleration winding WRb that auxiliary winding WA uses, flow through the electric current with main winding WM homophase, produce resultant flux with auxiliary winding WA, so total magnetic flux reduces, torque reduces and realizes slowing down and rotate.
