Abstract
1405336 Electric motors MALLORY TIMERS Ltd 28 Feb 1973 [28 Feb 1972] 9851/73 Heading H2A In an electric motor comprising a permanent magnet rotor 22 coupled to speed reduction gearing and rotatable within two interdigitated sets of stator poles, the stator comprises a mounting plate 10 engaged by the free ends of the legs 18<SP>11</SP> of a U-shaped stator member having an apertured base portion 18<SP>1</SP> formed with poles 30 extending into the aperture, a winding 24 disposed between the legs of the U-shaped member and a second stator member disposed between the winding and the base portion of the first member and having poles 32 interdigitated with poles 30. The rotor permanent magnet 52 may be of barium ferrite and positive starting is ensured by magnetic asymmetry of the stator and/or rotor. A ratchet and pawl mechanism 90 prevents wrong-way rotation. The rotor has a pinion 54 engaging the first wheel 58 of a four-stage speed reduction gearing assembly.
