Abstract
965,708. Electromagnetic couplings. BIBBY & BARON Ltd. Dec. 20, 1962 [Dec. 20, 1961], No. 45586/61. Heading H2A. In an eddy current drive coupling comprising a primary and secondary rotors 6, 3 connectable respectively to a driving source and a driven device, and a drive controlling stator 1 having a winding 2 for producing a magnetic field corresponding in magnitude to. an energizing current passing through the winding, the primary rotor 6 has on its outer cylindrical surface blades 7 which are inclined with respect to planes parallel with and passing along the rotor axis which blades draw cooling air over the rotor and increase the cooling surface area. The inclinatiin angle may be between 30 and 60 degrees, and the blades are either welded on or formed integrally with the rotor 6.
