1. An electric machine comprising:
- a housing;
a shaft arranged within the housing, the shaft including a first end and a second end;
at least one bearing mounted at one of the first end of the shaft and the second end of the shaft;
a stator mounted within the housing;
a rotor mounted relative to the shaft and rotatable relative to the stator; and
a temperature sensor integrated within the housing at the at least one bearing, the temperature sensor including a sensing element that detects a temperature of the at least one bearing.

Abstract
An electric machine includes a housing and a shaft arranged within the housing. The shaft includes a first end portion and a second end portion. At least one bearing is mounted at one of the first end portion of the shaft and the second end portion of the shaft. A stator is mounted within the housing and a rotor is mounted relative to the shaft and rotatable relative to the stator. A temperature sensor is integrated into the housing at the at least one bearing. The temperature sensor includes a sensing element that detects a temperature of the at least one bearing.

11. A method of operating an electric machine electrically connected to a motor control panel, the electric machine having a housing, a stator mounted within the housing, and a shaft including a rotor mounted adjacent the stator, the method comprising:
-
rotating the rotor operatively connected to at least one bearing relative to the stator; sensing a temperature of the at least one bearing with a temperature sensor integrated into the housing; passing power to the electric machine through a wire harness electrically coupled between the stator and the motor control panel; and passing signals representing the temperature of the at least one bearing through signal lines carried by the wire harness and electrically connected between the temperature sensor and the motor control panel. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
