Method and apparatus for braking a rotary component in a textile fiber processing machine

摘要

An apparatus for braking a rotary component of a fiber processing machine includes an asynchronous motor having a stator winding and an output shaft connected to the rotary component; a direct current generating device having an output connectable to the stator winding for applying an electric braking torque to the motor; and a switching arrangement for selectively connecting the stator winding to an alternating current source for normally driving the motor or to the output of the direct current generating device for electrically braking the motor.
