The SEE electromagnetic clutch is a positive clutch, current driven.
When a DC voltage is established in the coil, a magnetic field is generated that crosses the rotor with friction lining and attracts the armature, transmitting the movement.
When it does not receive current, the spring-membrane retracts the armature, in this way, the clutch disengages and stops transmitting the movement.
The SEE electromagnetic clutch is characterized by having 3 different construction types:
Construction 1.1.: It is the basic clutch unit, made up of the inducer, the rotor and the armature, with the riveted spring-membrane to be mounted directly on the pulley or pinion.
Construction 1.2: It is made up of the inductor, the rotor, the armature with the riveted spring-membrane and the pulley-holder or pinion bushing.
Construction 1.3: It is made up of the inductor, the rotor, the armature with the riveted spring-membrane and the aluminum hub to be mounted on another shaft.
