Abstract
An electro-mechanical actuator including a brushless DC motor for driving an output of the actuator; and a motor controller. The controller is configured to interrupt operation of the motor in response to at least one feedback signal representative of a motor parameter that varies with variation in a load on the output. The actuator output may be coupled to a window lift mechanism for moving a vehicle window between open and closed positions.
