Flange Mounted Electromagnetic Clutch Type EFMC (Normally Off)
Flange Mounted Electromagnetic Clutch Type EFMC (Normally Off)
EXCEL bearing and flange mounted clutches are normally off type and require DC voltage for operation. When stator (1) is supplied with D.C. voltage the armature plate (5) is attracted towards the friction material (4) of the rotor (3) over the air gap and torque gets transmitted free of backlash. When the supply is switched off the prestressed springs (6) pulls the armature (5) back into its original position free of residual torque even when mounted vertically.
