Claims
- 1. A brushless permanent magnet motor with a rotating motor shaft, comprising in combination;
- a main motor housing with a drive portion of said motor shaft extending from one end of said housing and an auxiliary component portion of said motor shaft extending from an other end of said housing;
- an encoder/resolver housing removably secured to said motor housing with said auxiliary component portion of said motor shaft passing through said encoder/resolver housing and extending beyond said encoder/resolver housing;
- a dynamic brake housing removably secured to said encoder/resolver housing with said auxiliary component portion of said motor shaft extending only partially into said dynamic brake housing;
- a back cover removably secured to said dynamic brake housing and alternatively to said encoder/resolver housing;
- said back cover including means for securing a dynamic brake to said back cover and to provide an end closure both when secured to said dynamic brake housing and when secured to said encoder/resolver housing.
- 2. A brushless permanent magnet motor as in claim 1 wherein said main motor housing, said encoder/resolver housing, said dynamic brake housing, and said back cover are removably secured together by bolts.
- 3. A brushless permanent magnet motor as in claim 2 wherein said bolts pass through bores in said main motor housing, said encoder/resolver housing, said dynamic brake housing, and said back cover.
- 4. A brushless permanent magnet motor as in claim 3 further including roll pins in said bores to prevent relative rotation of the housings.
