ABSTRACT:
An electric motor control system includes a housing and a motor disposed within the housing. The electric motor control system also includes an actuator operatively coupled to the motor and configured to operate in response to an operation of the motor. The electric motor control system further includes a controller disposed within the housing and communicatively coupled to the motor. The electric motor control system also includes a first electric conductor communicatively coupling the motor to the controller, wherein the controller is configured to supply power to and communicate a data signal with the motor over the first electric conductor.
