Abstract
873,163. Electric motor driving arrangements. EATON MANUFACTURING CO. Nov. 17, 1959 [May 1, 1959], No. 38887/59. Class 35. In a motor-driven eddycurrent clutch combination the motor rotor 42 and the magnetizable eddy-current drum 51 of the clutch are mounted on a hollow shaft 17 surrounding the clutch output shaft 16. The clutch is excited by a fixed coil 53 supported on a magnetic ring 52 with a retaining ledge 60 on a spider 55 (called a " diaphragm " in the Specification) secured to the casing. The inner rotor has interdigitated poles consisting of the ends of radial spokes 66, and a ring 64 having axially projecting poles 48 welded at their tips 73 to a supporting ring 72 which is, in turn, welded to the spokes 66. The flux circuit is shown at 89. The rotating polemember is of substantial C-shaped cross-section, the circuit being completed by the ring 52. The eddy-current drum is cooled by a member 84 of conductive metal, e.g. copper, soldered to the edge of the drum and having axially projecting cooling fins 86 which serve as fan blades. Fan blades 44 on the motor rotor, 78 and 79 on the outer coupling member, and 69 on the spokes 66, serve to draw air in at 34, 35 and out at louvred apertures 36 to cool the motor and clutch. Specification 803,505 is referred to.
