Claim Text:
1. A rotary electric machine comprising: a rotor that is arranged so 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; 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; a sensor guide that is arranged on an outside of the temperature sensor in a radial direction of the rotary electric machine, and that extends upward along the direction of gravitational force; and a first control unit that is configured to restrict a load of the rotary electric machine, wherein the first control unit restricts the load of the rotary electric machine so that a temperature that is detected by the temperature sensor does not exceed an upper limit temperature of the coil end when a flow rate of the coolant is lower than a predetermined threshold, and the first control unit restricts the load of the rotary electric machine so that the temperature that is detected by the temperature sensor does not exceed an upper limit temperature of the coolant when the flow rate of the coolant is equal to or higher than the predetermined threshold.
