Abstract

1,269,317. Rotors for electric motors. K. DIEHL. 16 Nov., 1970 [4 Dec., 1969], No. 54370/70. Heading H2A. A permanent magnet rotor for an electric motor comprises a permanent magnet 1 mounted on an injection moulded plastics part 2 on which is an injection moulded plastics pinion 3, the part 2 serving as a bearing for the rotor. The magnet 1 may be of barium ferrite. The part 2 may also include projections 5 (best depicted in Fig. 1, not shown) serving to prevent wrong-way rotor rotation.
