Electromagnetic clutches and brakes, from Suco

Suco electromagnetic clutches and brakes use the principle of the electromagnet to transmit power (clutch) or slow down a speed (brake). A stator contains a coil made of copper wires and molded with a synthetic resin. A clutch is active when a voltage is applied across the coil terminals. The generated magnetic field attracts the armature against the hub on the input side via the friction lining. There is then transmission of torque between the input and the output. When the coil is no longer supplied, the hub on the output side is no longer connected to the hub on the input side. A return spring returns the armature to the rest position, that is to say without connection to the hub on the input side. For a brake, the operation is similar, except that the magnetic field generated attracts the armature against the friction lining, allowing a braking torque to be transmitted to the hub on the output side. When the coil is no longer supplied, the return spring returns the armature to the rest position. The control of electromagnetic clutches and brakes therefore simply boils down to controlling the supply voltage.
