1. A rotating electric machine for an electric vehicle, installed in a vehicle and driven by an inverter power source, comprising:
a partial discharge measuring device that measures partial discharges occurring in insulated areas between windings, between phases and between the rotating electric machine and a ground, wherein
the partial discharge measuring device is configured with a temperature sensor that measures a temperature inside the rotating electric machine and an electromagnetic capacitance connected to ends of two output lines extending from the temperature sensor, with the output lines extending from the temperature sensor wound around an entire circumference of a stator core over an area near a coil end of the stator coil. |
