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:- The brake motor IS simple, rugged & so easy for maintenance.
- No separate DC supply is required. Rectifier is provided which gives the DC voltage for energisation of the brake.
- The rectifier is mounted inside the main TB. Separate TB not required.
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
Electric motor SF = 2-3
Brake Coil Conn. Diagram:
Brake coil is energized by DC side switching as shown in the diagram.
Enquiry Details:Please furnish the following :
- Application details
- Motor power & speed
- Brake size / required braking torque
- Mounting
- of start/stops per hour
- Duty cycle Note
- Selection chart is a general guideline for selection of brake size. If braking torque required is other than that mentioned in selection chart, this can be provided on request.
- Brake motors with safety factor less than 2 are not suitable for crane/hoisting applications.
- Motors up to frame sizes 132M can also be provided in aluminium housings.
- The motor must never 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 can also be provided on request.
