Classic Line – spring-applied brakes

Classic Line – Spring-applied brake, classic robust design with variable connection.

The Classic Line includes DC spring applied single and multi-disc brakes which, thanks to their robust design and variable connection technology, meet the requirements of demanding applications. Electromagnetically operated spring-applied brakes build up the braking torque when the power is switched off and the electromagnetic force is therefore neutralized.

Operating principle

The spring-applied disc brake is designed to operate in dry conditions. The force generated by an electromagnetic field is used to overcome the braking effect generated by the spring force. The spring applied multi-disc brake engages in the de-energized state and releases when DC voltage is applied. Brakes equipped with a built-in rectifier (half-wave or bridge rectifier) can be connected directly to an AC power source. The form fit between the friction disk and the hub and the connection of the hub to the machine (e.g. motor) shaft ensures that the torque generated by the spring-applied multi-disc brake (braking torque) is reliably transmitted to the machine (motor). The brake can also be equipped with an optional hand release so that the brake can be released manually.
