  • Human-machine interface for motor control
    Patent number: 8981684
    Abstract: A motor assembly includes an electric motor having a stator and a rotor. A housing is coupled to the electric motor. A motor controller is disposed within the housing. A human machine interface (HMI) is selectively detachably coupled to the housing and in communication with the motor controller. The HMI includes a user input for control of the electric motor when the HMI is coupled to the housing and for control of the electric motor when the HMI is separately disposed from the housing.
