EMP CLUTCHES & BRAKES For many years, MEROBEL has consolidated its position as the leader in EMP Brake & Clutch technology and associated electronics, especially for Wire &Cable and Web tension control, as well as variable torque simulation on test rigs. Today MEROBEL is a specialised division of REDEX ANDANTEX, which employs more than 300 people allover the world. MEROBEL is at the heart of a large network of agents, regularly trained to the highest standards and the latest of its technology, including four subsidiaries of REDEX ANDANTEX located in France, United Kingdom, Italy, and the USA. PRINCIPLE The EMP powder reactsto the variation of a magnetic field generated by an electromagnetic coil. Varying the powder's "viscosity" leads to the control of the torque transmission between the primary and the secondary rotors. When the secondary rotor is fixed to the equipment frame, the device is acting as a brake, otherwise it's acting as a clutch. FEATURES The torque is proportional to the electric current, the torque is independent of slip speed torque repeat ability BENEFITS Low Power Consumption Easy Installation Quiet Operation No Dust EMP BRAKES & CLUTCHES FAT- FRAT- FVRAT- FVAT- FRATO - Brakes Based on the same universal and robust design, these EMP through shaft brakes offer up to 5 different heat dissapation levels. EAT- ERAT- Clutches The clutch version of the above EMP brake series. These through shaft brakes are coverted to clutches by the addition of slip rings and brush holders. FAS- FRAS- Brakes EFAS- Clutches EMP clutches with a staionary coil, No brushes or slip rings EMP brakes with an external shaft LC Series - Torque Limiters MP Torque Limiter (no power supply). The torque is set by the position of the adjusting ring. WEB TENSION CONTROL The ultrasonic sensor measures the web diameter (without any contact with the product). The controller varies the brakes torque to keep the tension at a constant level. The tension force is generated by a dancing roller with a closed loop position regulation. The controller ensures that the web tension given by the brake's torque keeps the position stable and constant. Operating with load cell feedback, the controller continuously corrects the required brake's torque to keep the tension stable and constant. The realtime actual tension measurement value is available to the user.
