An electrical appliance includes a housing carrying a drive motor, a temperature sensor and a controller. The temperature sensor monitors the operating temperature of the drive motor. The controller is responsive to the temperature sensor. The controller adjusts the current applied to the drive motor in response to a high temperature condition detected by the temperature sensor.
