Title: Electric motor with oscillating armature
IPC: H02K7/065
Filed: 1963-04-25
Abstract: 1,035,694. Ratchet gearing. DANFOS A.S. April 25, 1963 [April 27, 1962], No. 16368/63. Heading F2Q. [Also in Division H2] Disc member 5 is driven in one direction of rotation from a continuously oscillating motor armature 1 by a frictional ratchet arrangement comprising an electromagnetically operated clamp which engages the disc in phase with the armature oscillations. The oscillating armature comprises a resilient portion 4 and a bifurcated portion having arms 7, 8 with arm 7 supporting an electromagnet 10. In operation either driver coil 2 or 3 is supplied with alternating current so that armature 1 oscillates at twice the supply frequency and electromagnet 10 is also energized from the same supply so that poles 11, 12 of the arms will clamp against the disc during one half cycle of the movement thus rotating the disc in a series of steps in one direction. The reverse direction is obtained by energizing the other driver coil. In order to vary the stroke of the device and hence the speed of rotation, mounting plate 14 is adjusted in slots 15 so that the radius at which clamping occurs is changed. In modifications, the disc may be of non-magnetic material and various dispositions of the parts used including the case where the disc spindle is used to support the oscillating armature. In a further modification the clamping arms surround the periphery of the disc and can be made to either clamp or release during energization of the electromagnets. Instead of a rotary movement of a disc the device could be used for linear displacement of a strip.
