BFK458

Operating Instructions

Electromagnetically released spring-applied brakes are used wherever masses in motion have to be decelerated as quickly as possible or where masses must be held in a defined position. The braking force is applied by tappet springs. Thus the braking torque generated by friction locking remains available in the deenergised status - even in the event of mains failure. The brake is released electromagnetically.

The main components of the modular system are the two basic modules E (adjustable braking torque) and N (non-adjustable braking torque).

A Powerful & Complete Range:

  • 9 sizes
  • Standard voltages [V DC] 24, 96, 103, 170, 180, 190, 205
  • Graduated torque range from 1.5 - 600 Nm
  • Short delivery times for the complete range thanks to optimised logistics
  • Degree of protection corresponding IP54, depending on the particular operating conditions
  • ATEX: In accordance with Group II, Category 3G/D, the product is suitable for use in potentially explosive atmosphere of zone 2 (gases and vapours) and zone 22 (dust) for steady-state operation (holding or parking brake) and temperature class T4.

INTORQ BFK458 spring-applied brakes are single disk brakes with two friction surfaces. When deenergised, several springs are used to generate the braking torque through friction locking. The brake is released electromagnetically. During braking, the springs use the armature plate to press the rotor (which can be shifted axially on the hub) against the counter friction face. When the brakes are applied, an air gap sL is present between the armature plate and the stator. The stator's coil is energised with DC voltage in order to release the brake.

Reliable:

  • The certified ISO 9001 and ISO 14001 quality assurance system provides the basis for consistently high-quality products
  • Production and testing to VDE 0580

The resulting magnetic flux works against the spring force to draw the armature plate to the stator. This releases the rotor from the spring force and allows it to rotate freely. Basic module E supports the use of the torque adjustment ring to reduce the braking torque.

Options:

  • Hand release for all sizes, both directions can be used for release and mounting (exception: tacho brake)
  • Noise-reduced designs
  • Various types of corrosion protection and enclosures
  • Microswitches used to monitor air gap and wear (size 12 and above)
  • Monitoring of Hand release function
  • Non-standard voltages and bores on request
  • Pulse width modulation (PWM), sizes 06 - 18 Partial discharge free brake has been developed for operation with the pulse width modulated DC bus voltage of a frequency inverter Rated coil voltage UN=103V DC

The LongLife design can be configured for sizes 06 to 12 in combination with the specified rated torques in the modular system. The stator corresponds to design N; bores and built-on accessories are not possible at the rear side. It is not possible to configure a microswitch for size 12.
