GENERAL

The VORTEX Type EKA is a ready to be installed electromagnetic actuated clutch-brake module. Our long-standing
co-operation with industry has enabled us to understand its drive requirements, helping us to produce products, which are the latest technological standard.

High-grade materials, the use of state of the art modern machine tools and uncompromising production and performance inspections guarantee reliability and safety.

The field of application for the VORTEX Type EKA clutch-brake module is immense, wherever machine parts are to be started and stopped quickly and efficiently. The benefit over other system is that the input side can be run continuously. The start/stop is performed by the EKA, therefore, considerably reducing power consumption.

This EKA Catalogue described the operations modes and details the various mounting designs that can be achieved using the modular principle. In many cases, a tailor-made solution could optimally fulfill your requirement.

These modules can be available in the combinations of the well-proven VORTEX EAA series single disk brake, EBA series single disc brake, ERD series fail safe brakes. Hence apart from the standard EKA versions numerous further combinations possibilities are available.

SWITCHING Our Clutch-Brake combination unit requires D.C. supply voltage, which is obtained through A.C./D.C. rectification. Normally switching is carried out on the A.C. side. However, for mush faster engagement / disengagement time, switching is carried out on the D.C. side for which a suitable arc suppressor and a capacitor is a must to protect the coil and switches from high induction voltages. Engagement / disengagement time is a function of nominal release distance.

WORKING

When D.C. Power is supplied to Clutch coil, rotor attracts armature assembly, thus transmitting torque from drive connected to input shaft via clutch to load connected through output shaft. On withdrawal of current from clutch, relay contactor or some suitable circuit when used automatically diverts the current to brake coil, thus instantaneously disengaging drive and simultaneously stopping output shaft connected to load via brake.

VORTEX is able to provide a wide range of possibilities with these modules some of which are shown below :
