A rotary electric machine includes: a stator core that is formed of a plurality of split core pieces that are annularly arranged therein, coil conductors being wound around respective split core pieces. One ends of the respective coil conductors which are wound around the respective split core pieces are connected to power supply terminals for corresponding phases, and other ends of the respective coil conductors are connected to each other to form a neutral point, the respective coil conductors are formed of rectangular wires, and the neutral point-side end portions of the respective coil conductors are led to an outside of the stator core from one point on a circumference of the stator core.

Rotary electric machine

A rotary electric machine includes a stator around which coil conductor wires for a plurality of phases are wound, a housing that contains the stator, and a terminal block that is mounted on the housing and connects end portions of the coil conductor wires for the respective phases led from the stator to corresponding external power supply lines. A coolant is supplied to the stator in the housing. The terminal block includes: a plurality of relay conductors, each relay conductor having one end connected to an external power supply line and the other end connected to an end portion of the coil conductor wires for 10 the respective phases, and a terminal block body that is made of an insulating material and holds the plurality of relay conductors.

A rotational axis of a first motorA and a rotational axis of a second motorB are disposed on the same straight line. A connectorof the first motorA and a connectorB of the second motorB are disposed substantially in mirror symmetric positions, and a lead conductorof the first motorA and a lead conductorof the second motorB are disposed in non-mirror symmetric positions, and a size of a relay conductorof the first motorA and a size of a relay conductorof the second motorB differ from each other.
