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.

Rotary electric machine, stator thereof and manufacturing method thereof

A rotary electric machine includes a stator. The stator has a coil end provided by a plurality of joint portions. The coil end has a leader wire connected to a power terminal. The stator has a coil end provided by a plurality of turn portions. The coil end has a circumferential pair whose top portions are offset in a circumferential direction. The circumferential pair has a height HG. The coil end has an axial pair whose top portions are offset in an axial direction. The axial pair has a height HG. The housing has a facing surface facing the coil end. The coil end provides a height distribution which adapts an unevenness of the opposing surface.
