MOTOR-BRAKE Russian patent published in 2006 - IPC H02K17/12 H02K7/10

Abstract RU 2287889 C1

FIELD: electrical and general mechanical engineering; self-braking motors built around squirrel-cage induction motors.

SUBSTANCE: stator and rotor contacting surfaces of motor-brake built around squirrel-cage induction motor are provided with taper thread; rotor shaft is supported on one end by radial bearing and on other one, by thrust bearing with spacer disk affording cohesion between stator and rotor threaded surfaces during reverse movement of rotor; shaft extension of the latter is splined.

EFFECT: simplified design, enhanced reliability of brake-motor.
