[0043] (rotating motor)
[0044]exist figure 1 Among them, the rotating electric machine for an internal combustion engine (hereinafter simply referred to as a rotating electric machine) 10 is also called a generator motor or an AC generator starter (AC Generator Starter). The rotating electrical machine 10 is electrically connected to a circuit 11 including an inverter circuit (INV) and a control unit (ECU). Circuit 11 provides a three-phase power conversion circuit.
[0045] The circuit 11 provides a rectification circuit that rectifies the AC power output when the rotary electric machine 10 functions as a generator, and supplies power to an electric load including a battery. The circuit 11 provides a signal processing circuit that receives a reference position signal for ignition control supplied from the rotary electric machine 10 . Circuit 11 may also provide an ignition controller that performs ignition control. The circuit 11 provides a drive circuit for making the...
no. 2 Embodiment approach
[0160] This embodiment is a modified example based on the previous embodiment. Figure 5 It is a winding diagram showing the arrangement of the stator coils 33 on the stator core 32 . In the following description of a plurality of embodiments, differences from the previous embodiments will be described. For the same or similar structures and methods, reference may be made to the descriptions of previous embodiments.
[0161] In the present embodiment, the stator coils 33 are formed in the order of u-phase coils, v-phase coils, and w-phase coils. In the present embodiment, the indexer 71 rotates the stator core 32 in the first conveying direction IDR1 (+) in the steps J11, J12, J21, and J22 for forming interphase jumpers PJ1a, PJ1b, PJ2a, and PJ2b. Also in this manufacturing method, after winding one phase coil of one group, the winding process for the other phase coil of the same group is started from the magnetic pole 32a adjacent to this magnetic pole 32a. Thereby, the le...
no. 3 Embodiment approach
[0163] This embodiment is a modified example based on the previous embodiment. Image 6 It is a winding diagram showing the arrangement of the stator coils 33 on the stator core 32 .
[0164] In the present embodiment, the stator coils 33 are formed in the order of u-phase coils, v-phase coils, and w-phase coils. In the present embodiment, in the steps J11 and J21 for forming the interphase jumpers PJ1a and PJ2a, the indexer 71 rotates the stator core 32 in the second conveying direction IDR2(-) by an amount corresponding to two magnetic poles 32a. . Also in this manufacturing method, after winding one phase coil of one group, starting from the magnetic pole 32a at the position after the magnetic pole 32a skips one magnetic pole 32a, a winding process for another phase coil of the same group is performed . Thereby, the length of the jumper wire PJ1a, PJ2a between these two phase coils in the circumferential direction can be controlled so that it may correspond to two magnet...
