A drive motor can also act as a generator. If the drive system is built so as to allow reverse power to flow then this power can be fed into a resistor, thus taking energy out of the system and causing whatever is driving the motor to slow down. Following to this the braking resistor converts the stop energy into heat. Electrical drive systems are being used more and more on ships, oil rigs, crane barges and offshore vessels of all types. An important benefit from using an electric drive is that reliable systems of regenerative and dynamic braking resistors are available to complement or replace traditional mechanical braking systems. The advantages of electric braking include control, reliability, mechanical simplicity, weight saving and in some cases the opportunity to make use of the regenerated braking energy. The Braking Resistor Units from Klöpper Therm are designed according to specific applications.

The spring-applied brakes which are ideally suited for robotics is designed for robotics solutions and loads of up to appr. 20 kg, but it can also be used in other applications requiring small geometrical dimensions. With regard to their power density the slim single-disc brakes are flatter and lighter than the market standard, and due to their large inner diameter they are well suited for hollow-shaft drives. This makes them perfect for applications in lightweight robots with integrated drives. There is a growing demand for safety technology in order to avoid injuries by collisions, especially if the control technology or even the power supply fails. In this case electromagnetic brakes are usually the method of choice. As safety brakes they bring moving masses to a stop, keep loads in position and therefore prevent humans and material assets from being affected.

The spring-applied brakes of the INTORQ BFK453 series were specially developed for use in industrial trucks. Particularly in reach trucks, they enable load-dependent braking or higher speeds. The latter results in shorter cycles and thus more efficient operations. What makes this fail safe brake particularly unique is the high braking torque and small installation space. The compact design means that lower access heights are possible on the industrial trucks, thus enabling much more ergonomic designs.

Electromagnetic brakes are used wherever moving masses have to be driven or decelerated as quickly as possible. Our wide range of products covers a wide variety of requirements. All brakes can be used in any installation position and require hardly any maintenance. All variants are powerful and operate with all-round safety and reliability. They feature short operating times, low inertia torques and ventilation that is free of residual torque.

High braking torque and small installation space: The compact and powerful BFK464-R dual-circuit spring-applied brake from INTORQ does it economically. This brake works with a split armature plate and two independent coil circuits. It reliably complies with the legal requirements for redundancy, such as for use in passenger elevators. In addition to the reliable braking torque, the high switching dynamics add even more safety. Switching noises are kept to a minimum. This is achieved by the well-engineered damping system. Another plus is the compact design: The rotor neck only minimally protrudes into the motor bearing shield, and the gear teeth of the rotor are particularly short.

Wherever there is only a very limited installation space available and a powerful brake is still required, we are sure to be “new fans”. Developed from the requirements of the industrial truck industry, the advantages of the BFK552 will certainly also make you curious in intralogistics and in the area of all general motor applications!

The BFK455 double-brake from INTORQ is a dual spring-applied brake with four friction surfaces and two electrically and mechanically separated brake circuits. The brake circuits can be individually controlled. Separate connecting lines can be used to control the brake circuits individually. The switching state of the two spring-applied brakes is monitored by two individual microswitches. The dual spring-applied brake is designed for one brake alone to provide the necessary braking torque. The second brake is used for redundancy, thus complying with the legal requirements for elevator standards. The BFK455 dual spring-applied brake from INTORQ is a redundant brake system with effective and stable noise reduction. It is ideally suited to elevator and platform applications.

Whenever the going gets tough, our BFK470 spring-applied brakes promise reliable performance. We have designed this IP66-sealed product line especially for dusty or humid operating conditions – such as wind power or crane facilities. Even extreme temperatures don't bother these brakes. They feature consistent protection and a unique modularity. You benefit from optimal versatility by using components which are freely configurable with each other. In other words, you get many variation options, all with rapid delivery times.

When operating in crane and port facilities, a braking system must primarily be reliably protected and, secondly, must operate very powerfully. The INTORQ BFK 471 product series combines these two features perfectly. These specially sealed brakes have a newly designed hand-release mechanism which, like the brakes themselves, is IP66 compliant. This series also features high braking torque and requires only a compact installation space.

Electromagnetic clutches are used wherever moving masses have to be driven or decelerated as quickly as possible. Our wide range of products covers a wide variety of requirements. All clutches and brakes can be used in any installation position and require hardly any maintenance. All variants are powerful and operate with all-round safety and reliability. They feature short operating times, low inertia torques and ventilation that is free of residual torque.

Kendrion (Aerzen) Mini Permanent magnet brakes open electromagnetically. The braking torque without backlash is generated by permanent magnets. The brakes can be installed in any position. High quality magnets ensure safe functionality. The rated torque is achieved immediately at the time of delivery without any running-in procedure.

The main characteristic of the magnetic particle clutch is the possibility to smoothly change the torque depending on the field voltage. To transmit the torque from the external to the internal rotor, specifically alloyed and highly abrasion-resistant iron particles are inserted into the particle gap. Depending on the electromagnetic field, these fine iron particles build magnetic chains and thus transmit the torque. The power of the field determines the stability of the particle chains and also the transmittable torque.

Electromagnetic clutches and brakes of Kendrion (Aerzen) GmbH are easy to install and integrate into the machinery concept/layout with no setting up or running in. Kendrion offers a combination fitted on a hollow shaft for applications where clutches and brakes work together. The units are based on the successful magneta components. They are fitted on a through shaft. The unit is fixed using simply two screws and is ready for operation then. Electromagnetic clutches and electromagnetic brakes from Kenrion (Aerzen) GmbH transmit the drive torque and braking torque frictionally in dry running conditions. If a DC current is applied, the torque is transferred without backlash. Residual torque free ventilation in a de-energised state is ensured by the prestressed annular spring of the armature section. The clutches and brakes are suitable for every mounting position and require almost no maintenance.

The EEX Line includes spring-pressure single-disc brakes provided with explosion protection for explosion-hazardous areas. The spring-pressure brake with firedamp protection is suitable for underground excavations with danger of firedamp. In spring-pressure brakes with explosion protection, those parts which might ignite explosive mixtures are incorporated in a housing. If the mixture inside the housing explodes, the latter prevents a transfer of the explosion to the mixtures surrounding the housing. The brake is equipped with four thermal circuit breakers and one micro-switch. The micro-switch prevents starting against the unlifted brake. The thermal circuit breakers are series-connected with the micro-switch and interrupt the control circuit of the machine as soon as there is an inadmissibly high temperature at the brake. The brake is seawater-resistant. By means of the attached hand lifting feature, the braking effect can be manually neutralized.

The High Torque series combines the well-known properties of permanent magnet brakes - Due to a re-design of the magnetic circuit, it features further advantages such as a higher torque at identical size and power consumption, high torque constancy throughout the complete service life and an extended temperature range. The High Torque brake is designed to operate dry. The force generated by a permanent magnetic field is utilised to produce the braking effect. To neutralise the braking action, the magnetic flux of the permanent magnets is cancelled by an alternate electromagnetic field (electromagnetically released system). The zero backlash connection between the armature and flange hub ensures zero backlash transmission of the brake torque to the machine shaft (e.g. motor shaft) and reliable release of the High Torque brake with zero residual torque. Thanks to these features, High Torque brakes are ideal for servo motor applications.

The PM Line includes permanent magnet brakes in which the braking force is generated by a permanent magnetic field. The brake thus works in a de-energized condition and fulfill the following functions: Holding, positioning and emergency stop. The neutralization of the braking force is effected by the counteracting electric field, granting a high degree of security, even in the case of power failure. Permanent magnet brakes are characterized by a secure, residual-moment-free lifting in any position, and by a backlash-free transfer of the braking torque. Therefore, they are ideal for servo motor applications.

The Slim Line includes spring-pressure single-disc brakes for brake discs mounted non-positive on the shafts to be retarded. The brake disc, which is permanently connected to the shaft, can be designed as a motor fan. Owing to the single-disc brake design, SLIM LINE brakes are particularly flat. Based on the working principle, residue-free lifting is achieved. Electromagnetically-operated spring-pressure brakes build up the braking torque when the current is switched off.

The VARIO LINE includes DC spring-pressure single-disc brakes, which can be matched to the individual application due to a wide range of variants. Electromagnetically-operated spring-pressure brakes build up the braking torque when the current is switched off. By means of the electromagnetic force or an additionally mounted hand lifting device, the braking effect can be neutralized. Fitting dimensions and the grading of the type series of the VARIO LINE are matched to IEC motors.

Electromagnetic clutches and brakes by Kendrion (Aerzen) transmit the torque and brake torque through dry running friction material. With DC voltage applied, the torque is transmitted without backlash. Using the prestressed spring of the armature, a release, free of residual torque is ensured. These clutches and brakes can be installed in any mounting position and hardly need any maintenance. Kendrion (Aerzen) offers standard clutches from 0.3 to 3.6 Nm as well as customer- and application-specific solutions up to 5 Nm.

The spring-applied single-disc brakes in the Servo Line series are designed to operate dry. They can be mounted to the A-face or B-face end shield inside the servo motor. The braking action generated by the compression springs is neutralized by applying the electromagnetic principle involving generation of a magnetic field. The brakes engage in unpowered condition and release when DC voltage is applied. The brakes are equipped with a flange and firmly fastened with screws. Thanks to a specially developed and patented manufacturing method, the rated air gap tolerance can be reduced to a few hundredths of a millimetre, providing enhanced power. Moreover, the brakes have a toothed hub/friction disc connection with minimal circumferential backlash. Standard version is suitable for flange mounting and face mounting.

The Active Brake Line includes DC single-disc brakes, in which the action of force of an electromagnetic field (electromagnetically closing) is used to generate the braking force. The Active Brake Line is characterized by a secure, residual moment-free lifting in any position, and by a backlash-free transfer of the braking torque. Throughout their complete service life, they require little or no maintenance.

The Elevation Line includes both DC spring-pressure single-disc brakes as well as spring-pressure double-disc brakes which comply with EN 81 (Safety Regulations Concerning the Design and Installation of Elevators). Integrated micro-switches allow for remote inquiry of the brake condition (armature position, wear, armature bearing). Owing to the patented safety concept, the otherwise mandatory testing of the dual-circuit braking system of the spring-pressure brake at the approval of the elevator system can be dropped. The brake can be used in places where short construction lengths with respective system components like motor, gear and brake must be realized. The Elevation Line is primarily used for elevators, but can be used wherever the brake must meet demanding safety requirements. Electromagnetic spring-pressure brakes build up the braking torque when the current is switched off.

The Compact Line includes spring-pressure single-disc brakes that can be mounted as complete units to the motor with very little assembly work. The compact design is of advantage when limited space complicates mounting. Electromagnetically-operated spring-applied brakes build up the braking torque when the current is switched off.

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