Brake Motors


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 Brake motors are printing machinery, textile machinery, rolling mills, cranes & hoists, material handling equipments, machine tools etc.

 KW : 0.18 to 55.0 kW


 Pole : 2P, 4P, 6P & 8P


 Mounting : B3, B5, B14 & combinations


 Frame : 63 to 250MX


 Motor Voltage : 415V±10% or as required


 Frequency : 50Hz±5% or as required


 Braking torque : Up to 800Nm


 Brake coil voltage : 190V DC (Other voltages on request)


 Protection : IP54


 Duty cycle : S1 – S8


 The brake motors are simple & rugged & so easy for maintenance.


 No separate DC supply is required as the rectifier is provided which gives the required DC voltage for energisation of the brake.


 The rectifier is mounted inside the main terminal box so no separate terminal box required.
