Abstract
1433105 Electric motors CONTROLS CO OF AMERICA 22 March 1974 [9 April 1973] 12788/74 Heading H2A A single-phase synchronous motor comprises a permanent magnet rotor 26 having a plurality of poles of alternate polarity on its periphery, the rotor co-operating with interdigitated stator poles 12, 20 formed respectively on casing parts 10, 18, the poles on each casing part being equiangularly spaced but the interdigitated poles being non-uniformly spaced to provide magnetic asymmetry to ensure starting. The poles 12, 20 are lanced out of the easing parts 10, 18 and, as shown in Fig. 3, the gaps G1, G2 between circumferentially adjacent poles are not equal. Each pole 12 has roughly twice the surface area of each pole 20. In a modification (Fig. 4, not shown), each pole 12 is split into two parts (112) each of roughly the same dimensions as each pole 20. The casing part 18 forms a gear housing.
