Abstract
A rotary electric machine includes a rotor and a stator. The stator has a coil end. The coil end has a plurality of lead wires. The plurality of lead wires have an inner lead wire with respect to the radial direction RD and an outer lead wire outside the inner lead wire with respect to the radial direction RD. The rotary electric machine includes a plurality of connection members. The inner lead wire and the outer lead wire are electrically and mechanically connected to the plurality of connection members. The plurality of connection members provide a heat transfer path from the inner lead wire. The inner lead wire and the outer lead wire demonstrate different vibration characteristics.
Claims8
A stator of a rotary electric machine, comprising:
- a stator core;
- and
- a stator coil mounted on the stator core and having a coil end protruding from an end of the stator core, and further comprising:
- an inner lead wire which extends out from a predetermined position with respect to a radial direction at the coil end;
- an outer lead wire which extends out from a position on an outer side with respect to the radial direction than the inner lead wire at the coil end;
- and
- a connection member which is a plate-shaped member positioned to face an axial direction end surface of the coil end, is thermally coupled to a power terminal extending outward, and is electrically and mechanically connected to the inner lead wire and the outer lead wire, wherein
- the inner lead wire and the outer lead wire are lead wires of the same phase winding, and wherein
- the inner lead wire and the outer lead wire are arranged on the same diameter line of the stator core.
