Abstract:
1. An actuator comprising: a threaded rod extending along an axis; a nut cooperatively engaging threads of the threaded rod, the nut being displaced along the axis upon rotation of the threaded rod; an electric motor rotating the threaded rod, the electric motor including a plurality of coils; a housing including a body portion and a coupling portion coupled directly to the body portion, the electric motor being disposed in the body portion; and a controller being disposed in the coupling portion and including a motor driver and a processor, the motor driver providing a drive signal to the plurality of coils, and the processor determining displacement of the nut with respect to the threaded rod based on a feedback signal generated in the plurality of coils during operation of the electric motor, wherein the controller is electrically connected directly to the electric motor via an electrical connector portion with electrical contacts mating directly with plug connectors, the electrical connector portion being constructed and arranged to be interchangeable with another electrical connector portion for mating with a different style of plug connectors, and wherein the feedback signal comprises a back electromotive force generated signal.
