Abstract
A horizontal axis washing machine includes an integrated motor and controller assembly. The controller is mounted to the electric motor with the controller positioned under a tub of the washing machine. The tub provides drip protection for the controller during operation of the washing machine. Additional embodiments include a motor and controller assembly in which a heat producing component of the controller is thermally coupled to a heat sink. The heat sink is positioned on an endshield of the electric motor and/or external to a housing of the motor controller. A stator of the electric motor can include one or more magnet wires attached directly to a connector for the motor controller.
