The INTORQ brand stands for reliable brake solutions of the highest standard. Whether in electric vehicles, cranes, wind turbines or lift systems - INTORQ products are used in the most diverse of applications. Rely on us to create the right solution for your drive - individually and reliably. The INTORQ company, with headquarters in Aerzen, started developing spring-applied brakes for servo motors at an early stage with its BFK418 range.
Based on the PM brake, the BFK418 was designed for mounting on the A-bearing side of the motor. Since then, the servo motor technology has been continuously refined. There has been progress especially in the friction linings and in the increased power of the magnetic circles.
So a spring-applied brake that has been designed as a pure holding brake can achieve the braking torque of a PM brake that is the same size. In Asia, the spring-applied brake in a servo motor has long been established as the standard solution. In Europe, the change-over has already started, and not only for reasons of cost. The new price- and performance optimised servo brake from INTORQ is called BFK417.

This modular system forms the basis for a product range that offers versions tailored for almost any task. The BFK458 spring-applied brake, as a standard product, can be used anywhere, but its modular structure also meets the requirements of specific industries. Its strength lies in its versatility.
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).
In high-cycle applications, spring-applied brakes are subject to two kinds of stress. Due to the large number of load alternations, the service life of the brake is determined both by the mechanical components of the brake itself and the useful life of the rotor, which is based on friction energy.
In particular, the rotor/hub connection, the springs and the sleeve bolts are subject to wear due to the number of load cycles. Based on the components mentioned, without additional measures the service life of spring-applied brakes is limited to 1x106 to 4x106 load cycles depending on the load.
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.
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.

High-power drives are achieving higher and higher motor speeds and drive torque levels. However, despite the increased performance requirements, the installation space allocated for brakes is actually getting smaller. The innovative multi-coil technology forms the basis for this performance class.
INTORQ BFK468 spring-applied brakes are single-disk brakes with two friction surfaces. When deenergised, several compression springs are used to generate the braking torque through friction locking.
The BFK468 models may only be operated with a half-wave bridge rectifier. The half-wave bridge rectifiers switch from bridge rectification to half-wave rectification after a fixed overexcitation time.
Terminals 3 and 4 are connected to the brake's DC circuit, while the induced voltage peak during DC operation (please refer to the circuit diagram entitled "Abbreviated switch-off times") is limited by an integrated overvoltage protection on terminals 5 and 6.
Direct drives for modern lift technology require brakes with high braking torques, fast response times and low levels of operating noise. The BFK466 with multi-pole technology satisfies all of these requirements and can also be adapted perfectly to the contour of the motor.
INTORQ brakes are designed so that the stated rated torques are reliably attained after a short run-in operation. Given the varying 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.
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.
The INTORQ range of spring-applied brakes is being expanded with the addition of the new BFK461 series of sealed designs. This brake has been specifically developed for application areas with high enclosure requirements.
It is a self-contained system available in seven sizes and with braking torques of 4-235 Nm is ideal for use in wind power plants, cranes and textile machines.
INTORQ BFK461 spring-applied brakes are single-disc brakes with two friction surfaces. When de-energised, several compression springs are used to generate the braking torque through friction locking. The brake is released electromagnetically. During braking, the compression springs use the armature plate to press the rotor (which can be shifted axially on the hub) against the counter friction face.
The INTORQ range of spring-applied brakes is being expanded with the addition of the BFK470 series of sealed designs. This brake has been specifically developed for application areas that place increased requirements on the degree of protection.
It is a self-contained system available in three sizes, and with braking torques of 40-250 Nm. It is ideal for use in wind power plants, cranes and textile machines.
BFK470 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 new high-performance braking system has been developed for use in crane systems, port facilities, ship winches, hoists, and belt conveyors. A new manual release has been designed specifically for this brake meeting the high requirements of the enclosure rating. The modular structure of the brake enables flexible use with single or dual rotor.
This brake is only to be actuated with a bridge half-wave rectifier (included in the scope of supply). The power input during the release is 440 W for 1.3 sec., then it is reduced to 110 W.
The spring-applied brake is designed for the conversion of mechanical work and kinetic energy into heat. Due to the static brake torque, the brake can hold loads without speed difference. Emergency braking is possible at high speed. The more friction work, the higher the wear.
