A rotary electric machine includes a rotor that is arranged such that an axis of rotation of the rotor extends in a horizontal direction, a stator that is provided with an coil end on which coolant is supplied from a position above the coil end in a direction of gravitational force, and a temperature sensor that is arranged on an outer peripheral face of the coil end at a position near a horizontal plane that includes the axis of rotation of the rotor. When the flow rate of the coolant is below a threshold the temperature sensor measures the coil temperature. When the flow rate of the coolant is above a threshold, so that coolant is in direct contact with the temperature sensor, it measures the coolant temperature. |
