ABSTRACT:
A unit bearing motor typically has an end shield, a stator core mounted within the end shield with the core extending axially out beyond the end shield. The core receives the windings of the motor and a winding cover is secured to the portion of the core extending out beyond the end shield so as to at least in part enclose the stator and the windings. The cover is a unitary member formed of sheet metal and has a peripheral rim at the end of the cover adjacent the end shield. The side walls of the cover have a plurality of indentations or dimples formed therein which locally engage the portion of the core extending beyond the endshield so as to securely hold the cover with respect to the core, but yet so as to permit the ready removal of the cover without damage to the cover or the windings.
