» Spring applied brake type BFK457

The basic solution, compact, quick assembly: completely assembled with flange, with integrated fixing screws.

Compact pre-assembled brakes that are fast to fit and particularly economical. The simple brake designs suit static or dynamic brake duties. Spring force applies the brake and current to a d.c. coil releases it. At the low end, these brakes are unique in providing simple spring aplied braking down to 0.12Nm.

» Spring applied brake type BFK458

The all-rounder, modular design a wide range of versions for practically every application.

This world-leading series of brakes is known for quality, reliability and long life. Spring force applies the brake and current to a d.c. coil releases it. The BFK458 replaces, and is interchangeable with the previous series 14.448. All models suit static and dynamic braking.

» The spring-operated BFK454

Brake for safe lift ascent and descent.

The specialist version, for use in lifts TUV-tested (German Technical Inspectorate), meets the requirements of TRA 200 and EN 81.

This electromagnetically released twin-circuit spring-operated brake is specially designed to meet the demands of lift technology. Used as a holding brake with emergency-stop function in the event of a power loss, the BFK454 ensures safe operation. The brake is TUV approved (German Technical Inspectorate) and meets the requirements of TRA 200 for lifts.

» Electromagnetic clutches & brakes

Do you need to speed up or slow down masses in motion within a short period? Using electromagnetic clutches, electromagnetic brakes provide high switching frequencies due to short switching times and low motor moments of inertia, transfer of torque without torsional play.

Clutches and brakes suit the disconnection, acceleration and braking of machine loads. The INTORQ Aerzen factory design and manufacture models in the torque range 7.5 to 480Nm. The nearby Magneta factory handle the miniature clutches and brakes designed and formerly manufactured by Lenze in a torque range 0.3 to 3.6Nm.

» SIMPLABLOC clutch-brake units

Does your production process run in cycles? With SIMPLABLOC, electromechanical clutch and brake units ensure the drive shaft is accelerated or slowed down with a constant drive speed.

SIMPLABLOC turns a continuously running drive into intermittent rotary motion controlled by a 24V dc signal.

» Moditorque Control - Mechatronic brake system

Spring applied brakes are normally on-off devices. However some applications call for control of torque and remote signalling. The Moditorque mechatronic brake system allows full brake control as if it were an 'electronic brake pedal' plus many more features.

Performance
Moditorque works with standard brakes sizes 08 to 20 of the BFK458 series. The standard Moditorque unit is configured for the brake size before shipment. According to the supply voltage, different brake sizes and torques can be achieved.

When the brake is released, Moditorque speeds the release by applying a short term over-voltage. Then the voltage is reduced to a pre-calculated holding level that is below the nominal rating. This lower voltage ensures faster brake engagement when the current is interrupted.
