This SEPAC stationary field multiple disc clutch is designed to operate both dry and in oil. Bearings used are sealed and permanently lubricated, and do not require a grease fitting like some competitive clutches. Many options are available.
When current is applied to the coil in the magnet body, a magnetic field is created which attracts the armature toward the rotor face. This causes the outer disc 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.
