Merobel Electromagnetic Particle Clutches

Overview:

These clutches provide torque proportional to the electric current, independent of the slipping speed, with low residual torque. They are easy to integrate into any type of system, achieving fast response time, linear, smooth, clean/dust free, silent operation with low wear and long life-reduced maintenance.

The thermal dissipation of these devices can by increased by the installation of cooling fins (radiator), blower kit or water-cooled devices.

Styles:

EFAS Series: Stationary Primary Clutches, torques up to 4 lb.ft.

EAT: Through Shaft Clutches, torques up to 752 lb.ft.
ERAT: Through Shaft Clutches with Cooling Fins, torques up to 752 lb.ft.
