Abstract

1292111 Core constructions NATIONAL RESEARCH DEVELOPMENT CORP 19 Dec 1969 [19 Sept 1968] 44618/68 Heading H2A The rotor of a reluctance type dynamoelectric machine includes a plurality of magnetically isolated segments 1 of magnetic material carrying a squirrel cage winding disposed in slots 2, and at least one of the segments has, extending circumferentially outwardly of the segment round the rotor periphery, at least one portion 3 similar in shape to the tips 5 of the segment teeth 6. Where provided at both circumferential ends of a segment, the portions 3 may have different dimensions at the opposite ends. The segments may have an axially extending quadrature axis flux barrier 12, Fig. 2 (not shown), disposed near the roots of the teeth 6; the flux barriers may be filled with conductive material. Alternatively, flux guides 21, Fig. 3 (not shown), may be provided in the segments. The flux barriers or guides may be disposed symmetrically or asymmetrically of the segment centre line 15. The different segments may have different spans and may have different numbers of slots 2 carrying the squirrel cage winding.
