By the way, we also distribute geared motors, servo motors, standard motors and special motors.

Applications: e.g. stage technology, gates & doors / automatic doors, cranes (turning, lifting, driving)

The INTORQ spring-applied brakes BFK458 are single-disc brakes with 2 friction surfaces. Compression springs generate the braking torque by frictional locking. The brake is released electromagnetically. When no current is applied, the brake is applied automatically.

When braking, the rotor is pressed against the friction plate by means of the compression springs. To release the brake, the coil in the magnetic part is placed under DC voltage. The magnetic force generated by this pulls the rotor away from the friction plate in the direction of the magnetic part against the force of the compression springs.adjustment ring.

Important: The friction surfaces must be kept free of oil and grease!
