Controllers for magnetic particle brakes&clutches - Controllers to excite magnetic particle brakes and clutches

The Active Clutch Line includes DC slip-ring-free single-disc clutches, in which the action of force of an electromagnetic field (electromagnetically closing) is used to transmit the torque. The clutches of the Active Clutch Line are characterized by a secure, residual moment-free lifting in any position and by a backlash-free transfer of the torque. Throughout their complete service life, they require little or no maintenance. Depending on the clutch version, higher switching capacities can be achieved.

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.

ESM for AC-brakes: The module consists of a time-controlled rectifier with integral electronic fast turn-off. During start-up, the ESM delivers bridge-rectified output voltage before changing over to half-wave rectification. The built-in voltage sensor ensures that the DC side output voltage is interrupted electronically when AC input voltage is removed. Thanks to its compact design, the ESM can be installed in very restricted space. ESM for DC-brakes: The module keeps the voltage supplied to the electromagnetic device at a constant level over a wide input voltage and temperature range. Full operating voltage is applied to ensure fast switching when the load is switched on. The module then reduces the power supply to constant holding voltage. A 30% reduction provides power savings of 50%. The ESM is very compact thanks to the use of state-of-the-art microelectronic and power electronic components. Overexcitation time and holding voltage can be factory-programmed to customer demands.

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.
