This SEPAC model "wet" clutch offers a wide selection of sizes, simple mounting and operation. The ERD clutch is recommended for applications in all oil atmosphere. Both 24VDC and 90VDC units are available. Maintenance free operation is featured since all wearing parts are hardened and the clutch automatically compensates for wear of disc pack.

OPERATION:
When current is applied to the clutch, flux flows through the discs to the armature. This causes the outer discs to be squeezed between the inner discs and the torque is transmitted from the input (rotor) to the output (spider). The magnet body is held stationary by means of an anti-rotation hole as specified by the customer.
