1. A motor assembly comprising:
- an electric motor including a stator and a rotor;
a controller housing coupled to the electric motor;
a motor controller disposed within the controller housing;
a terminal housing portion coupled to the controller housing and defining a first interface aperture, the terminal housing portion and the controller housing cooperating to define a second interface aperture;
a human machine interface (HMI) selectively coupled to the controller housing and decoupled from the controller housing and in communication with the motor controller when either coupled to the controller housing or decoupled from the controller housing, the HMI including a user input for control of the electric motor when the HMI is coupled to the controller housing and for user control of the electric motor when the HMI is separately disposed from the controller housing;
a first interface cord selectively connected to the HMI and the controller, the first interface cord passing through the first interface adapter when the HMI is decoupled from the controller housing;
a second interface cord selectively connected to the HMI and the controller, the second interface cord passing through the second interface aperture when the HMI is coupled to the controller housing;
wherein one and only one of the first interface cord and the second interface cord are connected between the HMI and the controller during operation of the motor assembly.

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.
