A motor assembly includes a flexible base mount having an axial tube, a rigid outer mounting shell member inserted into and retained to the axial tube by retaining and retained members disposed therebetween, a stator winding subassembly surrounding the outer mounting shell member and supported by resting on a surrounding ledge of the axial tube, a plug member engaging in a socket cavity of the outer mounting shell member, a flexible inner mounting shell member inserted into the outer mounting shell member, a rotating shaft of a rotor subassembly received in the inner mounting shell member and rotatably born by an antifriction bearing, and an upper positioning ring resting on the bearing. Leakage of lubricant and deformation of the inner mounting shell member can be prevented. |
