Description
The SER electromagnetic clutch is a positive clutch, i.e. 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 SER electromagnetic clutch is characterized by having 3 different types of construction:
- Construction 1.1.: It is the basic clutch unit, made up of the inducer with the rotor and the bearing and the armature, with the spring-membrane to be mounted directly on the pulley or pinion.
- Construction 1.2: It is made up of the inductor with the rotor and the bearing and the armature, with the spring-membrane and the pulley or pinion bearing bushing.
- Construction 1.3: It is made up of the inductor with the rotor and the bearing and the armature, with the spring-membrane and the aluminum bushing to mount on another shaft.
