Vario Line – single disc brake

The Vario Line includes DC spring-applied single-disc brakes, which can be adapted to the individual application thanks to a wide range of variants.

Electromagnetically operated spring-applied brakes build up braking torque when the power is switched off. With the help of the electromagnetic force or an additional mounted hand lifting device, the braking effect can be neutralized. Mounting dimensions and sorting of the VARIO LINE type series are adapted to IEC motors.

Operating principle

The spring-applied single-disc brake is designed to operate dry. The force generated by an electromagnetic field is used to overcome the braking effect generated by the spring force. The spring-applied single-disc brake engages in the de-energized state and releases when DC voltage is applied. The form fit between the friction disk and the hub and the connection of the hub to the machine shaft (e.g. motor shaft) ensures that the torque generated by the spring-applied single disk brake (brake torque) is reliably transmitted to the machine (motor).
