Abstract

816,190. Electromagnetic brakes. ALLMANNA SVENSKA ELEKTRISKA A.B. July 11; 1957 [July 17, 1956; June 8, 1957], No. 21981/57. Class 103 (1). [Also in Group XXXV] A brake disc 17 is released from a brake shield 18 upon energization of its associated motor which axially moves a magnetic armature 12 secured via a pin 15 to a rod 16 carrying the disc 17. Rotation is conveyed to the latter from the motor rotor shaft 5 by a key 22, hub 21 and pins 20. A spring 19 re-engages the brake when the motor is de-energized.
