Abstract
An integrated electric motor and controller assembly includes a motor, a controller mounted to the motor, and a sensor device disposed at an interface between the motor and the controller. The sensor device includes a sensor disposed at the controller and a magnet disposed at the motor. An alignment structure is provided at the interface between the motor and the controller for positioning the sensor relative to the magnet when the controller is mounted to the motor. The magnet is recessed in the motor and the sensor is protected by a controller housing of the controller. This arrangement has the advantages of protecting the sensor device from damage during shipment and assembly and providing a quick assembly and connection of the sensor device to the motor and the controller.
