Spring-applied-brakes - INTORQ BFK457

The Active Brake Line includes DC single-disc brakes, in which the action of force of an electromagnetic field (electromagnetically closing) is used to generate the braking force. The Active Brake Line is characterized by a secure, residual moment-free lifting in any position, and by a backlash-free transfer of the braking torque. Throughout their complete service life, they require little or no maintenance.

The PM Line includes permanent magnet brakes in which the braking force is generated by a permanent magnetic field. The brake thus works in a de-energized condition and fulfill the following functions: Holding, positioning and emergency stop. The neutralization of the braking force is effected by the counteracting electric field, granting a high degree of security, even in the case of power failure. Permanent magnet brakes are characterized by a secure, residual-moment-free lifting in any position, and by a backlash-free transfer of the braking torque. Therefore, they are ideal for servo motor applications.

Our reliable clutch/brake combination units are often used in synchronized facilities with mains synchronous input speeds. That’s because they are durable, easy to maintain and can be used in any installation position. The brake and clutch are within a compact housing. This ensures a simple and quick assembly process for you. And, thanks to INTORQ's patented wear adjustment mechanism, the air cap can be quickly adjusted.

The Elevation Line includes both DC spring-pressure single-disc brakes as well as spring-pressure double-disc brakes which comply with EN 81 (Safety Regulations Concerning the Design and Installation of Elevators). Integrated micro-switches allow for remote inquiry of the brake condition (armature position, wear, armature bearing). Owing to the patented safety concept, the otherwise mandatory testing of the dual-circuit braking system of the spring-pressure brake at the approval of the elevator system can be dropped. The brake can be used in places where short construction lengths with respective system components like motor, gear and brake must be realized. The Elevation Line is primarily used for elevators, but can be used wherever the brake must meet demanding safety requirements. Electromagnetic spring-pressure brakes build up the braking torque when the current is switched off.
