|Integral Brake Motors are suitable for various industrial application like Textile, Machine |
Tools, Hoists, Cranes, Lifts etc., where instantaneous stopping of the driven equipment is
|Motors are fitted with Electro Mgnetic Normally on brakes. |
|The electro-magnetic DC brake is mounted on the non-driving end of the motor. The cooling |
fan is mounted after the brake for better thermal dissipation and cooling of the brake also.
|Motor connection leads and brake coil leads are terminated in a single terminal box for |
easy connection, Rectifiers are supplied in loose condition and Manual release is provided
|WORKING PRINCIPLE |
|When power supply is given to the brake coil, the magnetic field produced by it, pulls the |
armature plate against spring force making rotor free to rotate.
|When power supply to the brake is removed, the armature plate will return to its original position instantly and due to axial force developed on the armature plate by the compression spring will not allow rotor to rotate. This will ensure instant fail safe in case of power failure.|
