Often, the brake is only required to perform its basic function. The BFK457 is ideal for these situations. The speed of fitting with integral fixing screws and fixed air gap make this spring-applied brake even more attractive.

BFK457

Operating Instructions

Thanks to the quality standards which we apply to research and development, production and assembly, the INTORQ BFK457 spring-applied brakes meet the highest demands. These electromagnetically released spring-applied brakes can be used wherever rapid deceleration of moving masses or controlled holding of masses is required.

Since the braking force comes from pressure springs, the braking torque, which is generated by friction, is available when no current is applied even in the event of a mains failure. The brake is released electromagnetically.

Fields of Application:

  • General engineering
  • Engine construction
  • Vehicles for the disabled
  • Automation technology
  • Sport and recreation
  • Rotary indexing technology
  • Industrial trucks
  • Hoists
  • Materials handling technology
  • Wood working machines

INTORQ brakes are designed so that the stated rated torques are reliably attained after a short run-in operation. Given the fluctuating properties of the organic friction linings used and changing environmental conditions, there may however be deviations from the stated braking torques. Appropriate safety factors in the design must take this into account.

Sizes 01/02/03/04/05:

  • Braking torques: 0.12-4 Nm
  • Compact: Fully assembled with rotor and flange
  • Can be mounted on both sides
  • Hand release available as an option

An increased breakaway torque may in particular be experienced in damp conditions and with changing temperatures after long downtimes. The braking torque should be checked when using the brake on the customer's friction surfaces. If the brake is being used solely as a holding brake without any dynamic load, the friction lining must be reactivated regularly.

Sizes 06/08/10/12/14/16:

  • Braking torques: 4-125 Nm
  • Emergency Hand release
  • Designs:
    • Compact: Fully assembled with rotor and flange
    • Basic: Stator complete with rotor
  • Hand release available as an option

AC Drives

For Some Applications fixed speed is acceptable and, by carefully selecting gearbox ratios, a desired final output speed can be achieved. However, for most applications, hard acceleration, unbraked deceleration and the inability to vary the speed and torque represent a serious problem. AC Drives are used to control AC induction motors; the most common motor technology used in industry.

Lenze Servo Motors

An Application-Oriented Structure low moments of inertia, compact dimensions and a high degree of intrinsic operational reliability characterise these robust and dynamic motors. Whether naturally ventilated or with blower - in a power range from 1.1 kW to 5.9 kW these servo motors provide rated torque values from 2.8 Nm to 17 Nm with peak torques of up to 52 Nm.
