Abstract

A motor assembly includes a motor, a controller controlling at least one aspect of operation of the motor, and a control housing defining a control chamber. The controller is in part received within the control chamber. The controller includes a main electronics board and a modular connector assembly. The modular connector assembly includes a secondary electronics board and a connector at least in part supporting the secondary electronics board. The connector includes an inner connector portion and an outer connector portion. The connector extends through the control housing such that the inner connector portion is disposed inside the control chamber and the outer connector portion is disposed outside the control chamber. The outer connector portion defines a first access portal facilitating access to a first component of the secondary electronics board.

First claim

What is claimed is:

1. A motor assembly comprising:
a motor;
a controller controlling at least one aspect of operation of said motor; and
a control housing defining a control chamber,
said controller in part received within said control chamber,
said controller including a main electronics board and a modular connector assembly,
said modular connector assembly including a secondary electronics board and a connector at least in part supporting said secondary electronics board,
said connector including an inner connector portion and an outer connector portion,
said connector extending through said control housing such that said inner connector portion is disposed inside said control chamber and said outer connector portion is disposed outside said control chamber,
said outer connector portion defining a first access portal facilitating access to a first component of said secondary electronics board,
said secondary electronics board including an inner secondary electronics board portion and an outer secondary electronics board portion,
said secondary electronics board extending through said control housing such that said inner secondary electronics board portion is disposed inside said control chamber and said outer secondary electronics board portion is disposed outside said control chamber.

2. The motor assembly of claim 1 ,
said modular connector assembly including another secondary electronics board,
said another secondary electronics board including another inner secondary electronics board portion and another outer secondary electronics board portion,
said another secondary electronics board extending through said control housing such that said another inner secondary electronics board portion is disposed inside said control chamber and said another outer secondary electronics board portion is disposed outside said control chamber.

3. The motor assembly of claim 2 ,
said modular connector assembly further including an additional secondary electronics board,
said additional secondary electronics board being disposed in its entirety inside said control chamber.

4. The motor assembly of claim 3 ,
said secondary electronics board comprising a communication board,
said another secondary electronics board comprising a power board,
said additional secondary electronics board comprising a wireless board.

5. The motor assembly of claim 1 ,
said modular connector assembly including another secondary electronics board,
said another secondary electronics board extending parallel to said secondary electronics board.

6. The motor assembly of claim 5 ,
said modular connector assembly further including an additional secondary electronics board,
said additional secondary electronics board extending parallel to said secondary electronics board and said another secondary electronics board.

7. The motor assembly of claim 6 ,
said secondary electronics board comprising a communication board,
said another secondary electronics board comprising a power board,
said additional secondary electronics board comprising a wireless board.

8. The motor assembly of claim 1 ,
said control housing including a cylindrical shell,
said outer connector portion and said outer secondary electronics board portion each being disposed radially outward of said shell.

9. The motor assembly of claim 1 ,
said first component being disposed outside said control chamber.

10. The motor assembly of claim 1 ,
said secondary electronics board comprising a communication board,
said first component being selected from the group consisting of a potentiometer and a switch.

11. The motor assembly of claim 1 ,
said outer connector portion defining a second access portal facilitating access to a second component of said secondary electronics board.

12. The motor assembly of claim 1 ,
said modular connector assembly including another secondary electronics board,
said another secondary electronics board comprising a wireless board,
said connector at least in part supporting said wireless board.

13. The motor assembly of claim 12 ,
said modular connector assembly defining a connector-receiving space configured to receive a wireless harness connector.

14. The motor assembly of claim 1 ,
said modular connector assembly including another secondary electronics board,
said another secondary electronics board comprising a power board,
said connector defining at least one power board connection opening.

15. The motor assembly of claim 1 ,
said modular connector assembly further including a top plate and a bottom plate fixed to said connector,
one of said top plate and said bottom plate at least in part supporting said secondary electronics board.

16. The motor assembly of claim 15 ,
each of said top plate and said bottom plate extending laterally from said connector.

17. The motor assembly of claim 15 ,
each of said top plate and said bottom plate including a resiliently deflectable latch component for securing said respective one of said top plate and said bottom plate to said connector.

18. The motor assembly of claim 15 ,
said one of said top plate and said bottom plate defining a connector-receiving space configured to receive a harness connector.
