ABSTRACT:
A dynamoelectric machine, preferably a motor adapted for use in ceiling fan applications, has a conventional rotor assembly mounted within a bore of a stator assembly. A stationary shaft extends through the rotor assembly and provides both a cableway for electrically connecting the motor to a source of electrical energy and for permitting the attachment of additional apparatus on one end of the stationary shaft. A retainer is mounted on the stationary shaft and positions the rotor assembly with respect to the stator. The rotor assembly is attached to a hub which rotates with the rotor and provides means for attaching blades to the motor. The stator is press fit into an end shield and the resulting structure is a compact, light weight, efficient dynamoelectric machine. The end shield is provided with means for attaching a decorative enclosure about the motor, so that the asthetic appearance of the motor can be enhanced substantially. The resulting structure is relatively low weight and enables a user to install the motor, and in particular, ceiling fans more easily than prior art devices.
