The Controller 14.422 serves to excite the magnetic particle clutches and brakes. The excitation current can be influenced by a dancer potentiometer or a master voltage. The built-in current controller ensures that, despite varying coil temperature the current is constant. Other important features of the controller are: Setpoint integrator, control amplifier and temperature monitoring through an optional thermal switch at the magnetic particle clutch or brake. Should the body temperature become too high, the controller simply switches off.

The main characteristic of the magnetic particle clutch is the possibility to smoothly change the torque depending on the field voltage. To transmit the torque from the external to the internal rotor, specifically alloyed and highly abrasion-resistant iron particles are inserted into the particle gap. Depending on the electromagnetic field, these fine iron particles build magnetic chains and thus transmit the torque. The power of the field determines the stability of the particle chains and also the transmittable torque.

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.
