Brake Motors are used for 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 EM AC or DC brake. The EM brake is mounted on the non–driving end of the motor.
DC brake motor is provided with a rectifier which provides the 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 motor main TB .
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 in the brake coil and this pulls the armature plate against the spring force and shaft is now free to rotate.
Special Features:Brake are rated by torque. Selection of suit. model can be made by cal. the required torque, Brake rating & matching it with static torque.
T (Nm) = 9550 x (KW / RPM) x SF
