STCC Operation:

When current is applied to the coil in the magnet body, a magnetic field is created which attracts the armature toward the rotor. As the teeth engage, torque is transmitted.

“When current is turned off, the armature slides on the splined hub to disengage from the rotor. Springs pull on the armature to assist. The bearing-mounted hub coupling assembly simplifies installation.”
