Abstract
A dynamoelectric machine includes a rotor assembly and a stator assembly mounted between endshields. The endshields have axial and radial apertures to assist in motor cooling. A motor shaft extends through one endshield. A mounting plate is provided for mounting the motor. The shaft extends vertically downward through the mounting plate, to which the transmission of a machine also is mounted. A drive pulley is attached to the motor shaft and a driven pulley is attached to the transmission shaft. The pulleys are maintained in planar alignment to permit transfer of power between the pulleys and to minimize belt wear. A second endshield has a bearing housing design which provides a flush endshield surface facing upwards towards the bottom of the machine. Motor height can be varied by increasing stator assembly stack height between the endshields to the extent permitted by the overall space available between the flush surface of the one endshield and the bottom of the machine. The motor mounting arrangement provides a two point mount which is varied to permit belt replacement, while maintaining alignment between the pulleys.
