Abstract:
The power distribution unit for a rotary electric machine includes a connecting ring unit that connects stator coils of the same phase. The connecting ring unit includes at least one linear conductor integrally formed in a ring-like shape, and the connecting ring unit includes a terminal section integrally formed in the linear conductor. The terminal section is constituted by a hole through which a wiring end of the stator coil is inserted and a protrusion formed in a direction of the hole to which the wiring end of the stator coil is connected. Also disclosed are a rotary electric machine includes the power distribution unit and a method for assembling a rotary electric machine.
