Abstract
The method of providing a motor, includes providing a first thin-walled end cap having first inner and outer walls connected by a first integral side wall, the first outer wall defining a first terminal edge; providing a second thin-walled end cap having second inner and outer walls connected by a second integral side wall, the second outer wall defining a second terminal edge; providing a stator, having multiple parallel laminations defining an axially extending bore to receive a laminated rotor, the stator having end laminations, positioning the end caps so that the edges extend adjacent stator opposite end laminations.
