Abstract

960,944. Eddy current brakes. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 9, 1963 [May 10, 1962], No. 18024/62. Heading H2A. A torque absorbing device comprises a stationary magnetic member 2, 3 which carries an exciting winding 7 co-operating with a rotating member which has blocks 11 of a high hysteresis loss, preferably grain oriented, magnet material. As shown blocks 11 are secured to a core 10 which is of steel or soft iron and laminated pole shoes 1 are attached on the outer surface of the block. The spaces between adjacent blocks may be filled with non-magnetic material e.g. aluminium, provided care is taken to eliminate any closed loops. In a modification the rotor may be planar and lie between two wound stator members, Figs. 3, 4, 5 (not shown), this construction is further modified by using a wound rotor and a stator comprising blocks of hysteretic material. The blocks may be made of " Alcomax " (Registered Trade Mark) which is grain oriented or Alnico which is not oriented.
