ABSTRACT:
Disclosed is a unique electromagnetic device, e.g. motor, construction in which a cylindrical tubular casing contains a stator assembly, a rotor assembly and bearings. The rotor assembly is supported by the bearings within the tubular casing which are in turn supported by a pair of end bells provided at each axial end of the tubular housing to close the same. Each axial end of the tubular housing contains, on an inner periphery thereof, an annular groove, at least one of the annular grooves having a tapered side wall at that side wall closest to an end of the housing such that the width of the associated groove progressively decreases along its depth. Each of the end bells contains a groove on an outer peripheral surface thereof which fits within the tubular housing, the outer peripheral grooves of the end bells substantially aligning with the interior peripheral grooves of the tubular housing. A pair of C-clips is provided in the opposing grooves at each end of the tubular housing with at least the C-clip provided in the groove with the tapered side wall having a complementary taper so that upon radial expansion of the latter C-clip, an axial force is generated tending to bias the two end bells together to axially clamp and hold together the stator assembly, bearings and rotor assembly.
