ac line

The AC LINE includes spring pressure single-disc brakes which can be connected directly and without rectifier to an AC supply, e.g. in the motor connection box. Due to its working principle the switching times of the brake are significantly shorter than with comparable DC brakes. Electromagnetically operated spring pressure brakes build up the braking torque when the current is switched off.

Application

AC Motors, Instrument Manufacture, Gear Motors, Handling Technology, Lifting and Conveying Technology, Crane Building, Paper and Printing Machines, Heavy Engineering, Gate Drives, Packaging Machines.

 

Selected Technical Details

Nominal Moment: 1 – 75 Nm

Voltage: DC 230, 400 V

Protection Class: IP 44, IP 54

classic lineThe 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-pressure brakes build up the braking torque when the current is switched off and the electromagnetic force is therefore neutralized.

Application

DC motors, handling technology, lifting and conveying technology, crane building, paper and printing machines

Selected Technical Details

Nominal torque range: 4 – 800 Nm

Voltage: DC 24, 102, 178 V

Protection Class: IP 54, IP 55

compact lineThe 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-pressure brakes build up the braking torque when the current is switched off.

Application

Machine tools, domestic and building engineering, wheel chairs

 

Selected Technical Details

Nominal torque range: 1 – 8 Nm

Voltage: DC 24, 102, 178, 230 V

Protection Class: IP 00, IP 54

eex lineThe 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 withstands the prescribed test pressure and 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. Electromagnetic spring-pressure brakes build up the braking torque when the current is switched off. By means of the attached hand lifting feature, the braking effect can be manually neutralized.

Application

DC motors, three-phase AC motors, gear motors, lifting and conveying technology, petrochemical industry, process engineering for explosion protected and explosive areas

 

Selected Technical Details

Nominal torque range: 10 – 270 Nm

Voltage: DC 205, 230 V

Protection class: IP 67

elevator drive

The ELEVATION LINE includes both DC spring-pressure single disk brakes as well as spring-pressure double disk 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.

Application

Elevators, Lifting and Conveying Technology, Cranes

Selected Technical Details

Nominal torque range: 5 – 440 Nm

Voltage: DC 205 V

Protection Class: IP 44

module lineThe MODULE LINE includes spring pressure single-disc brake modules for direct current which can be mounted as additional modules to a fully assembled motor – preferably to end shield A. Therefore, the MODULE LINE has an own bearing-mounted output shaft. The line is designed as a holding brake with emergency stop function. Electromagnetic spring pressure brakes build up the braking torque when the current is switched off. By means of the electromagnetic force or an additionally attached hand lifting the braking force can be neutralized during installation works.

Application

DC Motors, Gear Motors, IEC Three-Phase AC Motors, Servo Motors

Selected Technical Details

Nominal Moment: 25 – 500 Nm

Voltage: DC 24, 102, 178 V

Protection Class: IP 55

slim lineThe 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.

Application

Machine tools, domestic and building engineering, wheel chairs

Selected Technical Details

Nominal torque range: 0.25 – 3 Nm

Voltage: DC 24, 102 V; 1 AC 230 V; 50 or 60 Hz

Protection Class: IP 54

vario lineThe  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.

Application

Machine tools, DC motors, industrial trucks, gear motors, apparatus manufacture, handling technology, lifting and conveying technology, IEC three-phase AC motors, medical engineering,…
