A blower motor is provided for use in a machine. The motor includes a stator and a rotor rotatable about an axis. The stator includes a generally toroidal core, a first-main winding, and an auxiliary winding that is electrically out of phase with the first-main winding. The first-main winding and the auxiliary winding are both full pitch windings.

Induction motor having full pitch winding

An electric motor includes a stator and a rotor. The stator has a plurality of low speed windings and a plurality of separate high speed windings. A first type of thermal overload protector is coupled with at least one of the low speed windings and a second type of thermal overload protector is coupled with at least one of the high speed windings.

Multiple speed motor with thermal overload protection

An electric motor is provided. The motor is mountable to a machine. The motor includes a rotor rotatable about an axis, a stator, a housing, and a fastener. The housing includes a first endshield and a controller can, with the stator being positioned axially between the endshield and the can. The fastener extends through and interconnects the first endshield, the stator, and the can. The fastener projects axially beyond at least one of the first endshield and the can for connection to the machine.

Motor with sealed controller housing

An electric motor assembly includes a stator assembly and a rotor assembly having a shaft disposed within a motor case. The motor case includes an endshield with a centrally disposed bearing-receiving core that is configured to receive any one of a plurality of bearing assemblies, including at least a ball bearing and a self-aligning bearing, for rotatably supporting the shaft. The core includes a bearing assembly engagement surface with a generally cylindrical first portion and a generally frustoconical second portion, such that any of the selected bearings received therein directly contacts and engages the first surface portion or the second surface portion.
