Brake Motors

 

Introduction

Brake Motors are used for various applications, where instantaneous stopping of the driven load is required. The operation of the brake is "FAIL SAFE TYPE"i.e. normally ON> When the electrical power to the motor is cut-off or the power fails, the brake is applied. Brake Motor is a combination of an A.C. induction motor and an electromagnetic AC or DC brake. The electromagnetic brake is mounted on the non-driving end of the motor. DC brake motors are provided with a rectifier which provides the required DC voltage to the brake coil which in turn operates the brake. the supply to the rectifier is fed from any two terminals(between any two phases) in the main terminal box of the motor.

General applications of the Brake motors are printing machinery, textile machinery, rolling mills, cranes, Hoists, material handling equipments, machine tools etc.
 

Working :

when the power to the motor is switched off, a braking torque is generated which presses the armature plate of the brake against the mounting flange. When the supply resumes, a magnetic field is produced i9n the brake coil and this pulls the armature plate against the spring force and the shaft is now free to rotate.
