Abstract
1,103,302. Electromagnetic brakes. ALGEMENE KUNSTZIJDE UNIE N.V. 2 Feb., 1965 [12 Feb., 1964], No. 4540/65. Heading H2A. [Also in Division D1] An electric brake has a laminated rotor 4 with a squirrel cage winding 9 deeply embedded in the laminations which have radial slits 12 extending from the winding conductors to the air gap 7, and a stator 5 which provides a unidirectional magnetic field through the rotor. The motor is built up from insulated laminations with the copper bars 9 of the squirrel cage embedded half-way between the inner and outer peripheries of the lamination stack. The bars of the squirrel cage may extend helically along the length of the rotor. The parts are stated to be dimensioned such that the product of torque and speed is constant. The stator may have windings 6 supplied from a variable D.C. source or alternatively permanent magnets may be used to provide the magnetic field. It is stated that the brake is especially suitable for applications where a sheet or thread is unwound from a carrier.
