Abstract
A molded plastic housing for a small electric motor having a radial end wall and an axially projecting portion for mounting the stator and journalling the motor shaft. An annular stator is mounted on and about the projecting portion and shaft bearings are mounted in axially spaced relationship in interference fit respectively at end sections of the housing portion and in direct engagement with the molded plastic. Reduced diameter and reduced thickness zones at the end sections provide for resilient and firm bearing retention and alignment. Four (4) circumaxially spaced slots at each end section with flats radially inwardly thereof provide for the reduced thickness and reduced diameter. The bearings engage the flats in an interference fit.
