Title:
巻線形回転電機
Document Type and Number:
Japanese Patent JP7137427
Kind Code:
B2
Abstract:
To reduce the possibility of an inter-phase short circuit near the rotor end of a coil type rotary machine.SOLUTION: A coil type rotary electric machine includes a rotor 10, a stator having a stator winding passing through a stator iron core, and a stationary side transmission portion 60. The rotor 10 has a rotor shaft 11 and a rotor iron core attached to the outside of the radial direction thereof, a plurality of rotor windings that penetrate the rotor iron core, and a slip ring electrically coupled to each of the rotor windings of each phase. The stationary side transmission portion 60 has a brush holder 62 for each phase that holds a brush 61 for each phase that slides with a slip ring 15 for each phase and is coupled to an external cable, and a plurality of interphase-short-circuit prevention plates 100 formed such that each of the brush holders 62 of each phase is stationery-supported so as to sandwich each of them in the axial direction, and formed so as to include the range in which the brush holders 62 of each phase are projected within the range projected in the axial direction.SELECTED DRAWING: Figure 2
