Abstract

The application is typically to special purpose motors, for example direct drives for tubular mills or kilns. The rotor pole comprises a compressed stack of laminations (2) held between endplates (4). A mounting plate (3) forms part of the pole body but extends radially inwards to mate with the rotor hub (5). Attachment is typically by bolting through holes (6,7). The winding (1) may be secured in a conventional manner to the pole. For a machine with a large number of poles, the design may be modified to have a number of poles made up from one punching stack with a single mounting plate for attaching it to the hub. The cooling of the poles is even as they are fairly uniformly exposed to the ventilating air.
