Abstract
A motor manufacturing and its method of assembly are disclosed. The motor includes lower and upper end frames with bearings, an armature assembly rotatably mounted in the bearings of the lower and upper end frames, and a winding field assembly supported between the lower and upper end frames and surrounding the armature assembly. The method includes the steps of inserting one end of the armature assembly into the bearing of the lower end frame, positioning the winding field assembly over the armature assembly while also stacking the winding field assembly on the lower end frame, stacking the upper end frame on the winding field assembly while also positioning an opposite end of the armature assembly into the bearing of the upper end frame, and securing the lower end frame, winding field assembly and upper end frame to each other. Motor brush and brush holder assemblies are also secured to the upper end frame in a novel releasable locking arrangement, in order to provide self compensating adjustment of the brushes relative to a commutator that surrounds the armature assembly.
