Stator for Rotating Electric Machine

摘要

A new rotor for a rotating electric machine assuring outstanding durability and reliability against vibration and facilitating equalization of resistances among a plurality of rotor coils, while allowing the leading ends of a plurality of lead wires to be disposed so as to congregate in one area, is provided. A plurality of stator coils 102 wound at a cylindrical stator core 101 each include leader portions led out from one of two ends of a slot along the axial direction and extending astride a plurality of slots. Lead wires 300 each formed at one end of a stator coil 102 are disposed so that their leading ends, oriented in the same direction, congregate in a single area. In a leader portion where a lead wire 300 is located, a turnback portion 400, made to turn back with an angle equal to or greater than 90° from an inclining wire portion 113, which is led out with an inclination along a predetermined direction from the slot, is formed.

主权项

1. A stator for a rotating electric machine, comprising:
a stator core having a cylindrical shape; and a plurality of stator coils wound at the stator core, wherein: a plurality of slots passing through the stator core along an axial direction and set side-by-side along a circumferential direction are formed at the stator core; the stator coils each extend within the slots along the axial direction and also include leader portions each led out from one of the two ends of the slot along the axial direction and extending along the circumferential direction so as to run astride a plurality of slots, set apart from one another with a predetermined circumferential pitch; the leader portions each include an inclining wire portion led out from one of the two ends of the slot along the axial direction with an inclination along a predetermined direction relative to the axial direction; a lead wire via which a connection with an external device is achieved is formed at the leader portion to constitute one end of each stator coil, and lead wires each belonging to one of the plurality of stator coils are all positioned so as to congregate in one area with leading ends thereof oriented in one direction; and the lead wires each include a turnback portion formed to turn back from the inclining wire portion with an angle equal to or greater than 90°.
