Clutch-brake units

Electromagnetic clutches and brakes by Kendrion (Aerzen) transmit the torque and brake torque through dry running friction material. With DC voltage applied, the torque is transmitted without backlash. Using the prestressed spring of the armature, a release, free of residual torque is ensured. These clutches and brakes can be installed in any mounting position and hardly need any maintenance. Kendrion (Aerzen) offers standard clutches from 0.3 to 3.6 Nm as well as customer- and application-specific solutions up to 5 Nm.

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 Slim Line includes spring-pressure single-disc brakes for brake discs mounted non-positive on the shafts to be retarded. The brake disc, which is permanently connected to the shaft, can be designed as a motor fan. Owing to the single-disc brake design, SLIM LINE brakes are particularly flat. Based on the working principle, residue-free lifting is achieved. Electromagnetically-operated spring-pressure brakes build up the braking torque when the current is switched off.

The VARIO LINE includes DC spring-pressure single-disc brakes, which can be matched to the individual application due to a wide range of variants. Electromagnetically-operated spring-pressure brakes build up the braking torque when the current is switched off. By means of the electromagnetic force or an additionally mounted hand lifting device, the braking effect can be neutralized. Fitting dimensions and the grading of the type series of the VARIO LINE are matched to IEC motors.
