Abstract

684,745. Eddy-current apparatus. WINTHER, M. P. July 27, 1951 [Oct. 30, 1950], No. 17798/51. Addition to 658,311. Class 35. A clutch, eddy-current brake or dynamometer with an imbricated pole-member as claimed in the parent Specification has the cross - section of the polepieces increased adjacent the air gap to lower the flux density locally in this region. The coupling shown has a magnetic eddy current ring 21 carried by a spider 19 on one shaft 13 encircling the imbricated poles 23, 25 carried by spider 15 on shaft 11.
