Abstract

1409954 Electric motors with permanent magnet rotors SUWA SEIKOSHA KK and SHINSHU SEIKI KK 9 May 1973 [15 May 1972 30 May 1972] 22044/73 Heading H2A In a motor having a permanent magnet cylindrical rotor 11, the windings 14 for magnetizing the arcuately shaped pole pieces 12 of the stator are mounted on yoke members 17 extending axially from the polepieces 12 and the magnetic circuits 10 between the stator and the rotor are completed by a yoke plate 15 which supports one end of the rotor shaft 13; the axial separation of the rotor 11 and the windings 14 allows a compact low inertia motor to be formed. A non-magnetic plate 20 supports the other end of the rotor shaft 13, as well as projection portions 19 of the polepieces 12. In a modification (not illustrated), the members 17, the windings 14 and the yoke plate 15 are duplicated on the other side of the polepieces 12. The members 17 are preferably of smaller arcuate extent than that of polepieces 12 (as in Fig. 4, not shown), but they may be of the same size (as in Fig. 5, not shown). In the embodiment of Fig. 6 (not shown), the rotor (11) encircles the stator.
