Similarly, coil 12 makes and can use simple and economic connector (not shown), is used for especially winding ECx, ECy, the ECz of stator 10 are connected to the bridge rectifier (not shown).
Thereby, coil 12 makes and can use electric wire 11 that the end of winding ECx, ECy, ECz is connected to input wires Ex, Ey, Ez and output connection Sx, Sy, Sz, and these electric wires are identical and compare shorter with the electric wire of the coil that is used to have the simple wave form winding.
In addition, the coil 12 feasible mechanical strengths that can improve stator 10, because input wires Ex, Ey, Ez and output connection Sx, Sy, Sz are straight, as as can be seen from Fig. 7, this has been avoided input wires Ex, Ey on the sheet metal bag 14 of stator 10, Ez and output connection Sx, Sy, Sz are carried out bonding or use holding device.
Coil 12 according to the present invention makes and can reduce the manufacturing cycle, keeps some advantages of the coil that just comprises a plurality of distribution waveform windings of prior art simultaneously; These advantages at first are to simplify manufacturing operation, because during the same step of making, implement to peel off (baring), twisting and zinc-plated, next is close because of pair of connecting wires P1, P2, P3, and what no matter use is crimping (crimping), solder brazing (brazing), solder (soldering) or other method, can reduce to be used to carry out the change-over time that connects and the instrument of pair of connecting wires P1, P2, P3 is installed with trigonometric expression.
According to another embodiment (not shown), coil 12 according to the present invention comprises a simple wave form winding and two distribution waveform windings.
The present invention may extend into the stator 10 that comprises more than three winding ECx, ECy, ECz.According to changing routine (not shown), stator 10 can comprise two three-phase coils 12, and each all comprises three windings, that is to say six windings altogether.
According to this preferred embodiment that changes example, each three-phase coil 12 advantageously comprises a distribution waveform winding and two simple wave form windings.
Indefiniteness ground, each coil 12 with three windings comprises a simple wave form winding and two distribution waveform windings.
According to having six winding embodiment, the first distribution waveform winding is arranged on the inner radial position with respect to other five windings, and the second distribution waveform winding is arranged on the radially outer position with respect to other winding, and its purpose is still the minimizing injurious noise.
