ABSTRACT:
A compact AC-DC motor comprising a housing having a center section and respective end bells, each having a recess therein. A stator is received in the housing and extends into the recess in one end bell and a magnetic pole piece is similarly received in the housing and extends into the recess in the other end bell. Rotatably supported in the end bells is a shaft which mounts a rotor which cooperates with the stator, and an armature winding in juxtaposition to the rotor which cooperates with the pole piece. Additionally, a brush holder is affixed to the end of the pole piece whereby the construction provides a highly efficient motor which occupies a minimum volume of space.
