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.

Claims

1. A motor assembly comprising:

an electric motor including a stator and a rotor;

a housing coupled to the electric motor;

a motor controller disposed within the housing;

a human machine interface (HMI) selectively detachably coupled to the housing and in communication with the motor controller, the HMI including 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.

2. The motor assembly of claim 1, wherein the housing includes a stator housing and a controller housing.

3. The motor assembly of claim 2, wherein the HMI is selectively detachably coupled to the controller housing.

4. The motor assembly of claim 1, wherein the HMI includes a display screen.

5. The motor assembly of claim 1, wherein the HMI is coupled to the motor controller via an interface cord when separately disposed from the motor housing.

6. The motor assembly of claim 5, wherein the HMI is coupled to the control module via the interface cord when coupled to motor housing.

7. The motor assembly of claim 5, wherein the interface cord is a first interface cord, and further wherein the HMI is coupled to the motor control module via a second interface cord when separately disposed from the motor housing.

8. The motor assembly of claim 5, wherein the interface cord is coupled to a terminal housing portion of the controller housing.

9. The motor assembly of claim 8, further comprising a terminal cover coupled to the terminal housing portion, the interface cord entering the terminal housing portion through a gap defined by the terminal cover and the housing.

10. The motor assembly of claim 1, wherein the user input includes a program entry button.

11. The motor assembly of claim 10, wherein the user input includes a program override button.

12. The motor assembly of claim 1, wherein the HMI includes a fault indicator.

13. A motor assembly, comprising:

an electric motor including a stator housing, a stator disposed in the stator housing, and a rotor rotatably coupled to the stator housing for rotation with respect to the stator;

a motor control module including a controller housing coupled to the stator housing, a motor controller disposed within the controller housing, and an input terminal in communication with the motor controller;

a human machine interface (HMI) including an HMI housing, a display, a user input member, and a mounting member for selectively detachably coupling the HMI housing to the controller housing;

an interface cord connecting the HMI to the input terminal and communicating commands from the user input member to the motor controller.

14. The motor assembly of claim 13, wherein the mounting member defines an aperture for receiving a fastener.

15. The motor assembly of claim 14, wherein the mounting member is a mounting plate coupled to the HMI housing, the mounting defining a plurality of apertures arranged in a pattern.

16. The motor assembly of claim 15, wherein the controller housing defines a plurality of threaded apertures arranged to align with the plurality of apertures of the mounting plate.

17. The motor assembly of claim 13, wherein the controller housing includes a terminal portion, the input terminal disposed within the terminal portion.

18. The motor assembly of claim 17, further comprising a terminal cover substantially enclosing the terminal portion.

19. The motor assembly of claim 18, wherein the terminal cover at least partially defines a first aperture for receiving the interface cord.

20. The motor assembly of claim 19, wherein the terminal portion defines a second aperture for receiving the interface cord.
