Abstract
1485154 Dynamo-electric machines D L HORE 15 April 1975 [7 May 1974] 20057/74 Heading H2A A single or polyphase rotary or linear dynamoelectric machine includes an A.C. energized, wound, laminated stator 3 and a laminated movable member 1 carrying a short-circuited conductive loop E, E1, which causes the movable member to move until the flux linkage between the loop and the stator winding is minimized. Machines may be designed for limited angular movement, e.g. angular solenoids, or stepping operation. In the latter case a plurality of stator windings are energized in succession. For either mode of operation, where the stator has more than one winding, e.g. Fig. 5a, the winding not energized at a given time may be short-circuited to increase the aligning torque on the movable member. Where the stator has a three-phase winding, the rotor may have three short-circuited loops with their axes offset by 120 degrees, Fig. 3c (not shown).
