Abstract
A motor end cap and output device housing is provided that includes a motor end plate having an output device attachment area and a output device housing having a motor end plate attachment area. The output device attachment area includes a locking tab that mates with a slot portion in the output device housing to interlock the two together. As a result, the motor end plate can be conveniently attached to the output device housing without requiring extra fasteners.
Claims15
A motor and output device assembly comprising:
- a motor end plate fixably attached to a motor and having an output device attachment area;
- an output device having an output device housing, the output device housing having a motor end plate attachment area at one axial end of the output device housing;
- an attachment mechanism on the motor end plate attachment area;
- and
- an attachment mechanism on the output device attachment area, the attachment mechanism of the output device attachment area mating with the attachment mechanism of the motor end plate attachment area;
- wherein the motor end plate attachment mechanism and the output device attachment mechanism are rotatably connected to one another to form a quick connect/disconnect attachment.

5 more elements
A method for attaching a motor to an output device comprising the steps of:
- providing a motor end plate at an axial end of a motor, the motor end plate fixably attached to said motor and having at least one locking tab extending radially outward from the motor end plate;
- providing a output device housing having at least one circumferential slot portion circumferentially disposed on the output device housing, the output device housing having at least one downward slot portion connecting the circumferential slot portion to an axial end of the output device housing;
- positioning the motor end plate against the axial end of the output device housing to insert the locking tab into the downward slot portion;
- and
- rotating the motor end plate with respect to the output device to move the locking tab along the circumferential slot portion in a direction away from the downward slot portion.
