Brake Motors

Brake Motors are used for varied applications wherever fast stopping of the driven load is required. The operation of the brake is “FAIL SAFE TYPE” i.e. normally ON. Once the electrical supply to the motor is cut–off or the electrical supply fails, the brake is applied.

Brake motor may be a combination of an A.C. induction motor and an electromagnetic AC or DC brake. The brake is mounted on the non–driving side of the motor. DC brake motors are supplied with a rectifier that provides the specified DC voltage to the brake coil that successively operates the brake. The provision to the rectifier is fed from any two terminals (between any two phases) from the main terminal box of the motor. General applications of brake motors are pharmaceutical machinery, textile machinery, rolling mills, cranes & hoists, material handling equipment, machine tools, and many more.

When the supply to the motor is turned off, a braking torque is generated that presses the coil plate of the brake against the mounting projection. Once the supply resumes, a magnetic flux is made within the brake coil and this pulls the coil plate against the spring force and also the shaft is then free to rotate.

Note:

1. Selection chart is a general guideline for selection of brake size. If braking torque needed is other than that mentioned in selection chart, this can be provide on request.
2. Brake motors with factor of safety less than two are not appropriate for crane/hoisting applications.
3. The motor must not be switched “ON” unless brake is energized & the brake should never be de-energized when the motor is “ON”.

Brake motors with higher braking torque are also available on request.
