Fixed-Speed Torque-Limited Braking Type Magnetic Coupling for Industrial Drive Systems

The Fixed-Speed Torque-Limited Braking Type (FTL-BT) Magnetic Coupling is designed for industrial drive systems requiring torque transmission and emergency braking. With a rated power range of 15–1800 kW, it can be used in material handling equipment, pumps, compressors, fans, crushers, and other industrial machinery.

Its unique braking system enables emergency braking when required. The coupling also helps reduce mechanical stress during startup and absorb load shocks, supporting more stable equipment operation.

Emergency Braking and Mechanical Protection

The FTL-BT magnetic coupling integrates a braking function into the drive system. When emergency braking is needed, the braking system can be activated according to the equipment's operating requirements. This function is useful in industrial applications where controlled stopping is important.

The coupling also allows temporary system overloads and absorbs load shocks, helping reduce the impact of sudden load changes on connected machinery. Its non-contact torque transmission design eliminates direct physical contact between the motor and driven machine, reducing mechanical wear associated with contact-based transmission components.

Key Advantages of FTL-BT Magnetic Couplings

Reduced Maintenance Requirements

The coupling requires no lubrication, oil, or other chemicals for its magnetic transmission function. Its non-contact design helps minimize routine maintenance needs and can reduce the total cost of ownership.

High Transmission Efficiency

The manufacturer specifies transmission efficiency of up to 98% and potential energy savings of up to 70%, depending on the application and operating conditions. Actual results vary with the equipment configuration and operating load.

Flexible Installation

The coupling tolerates high levels of shaft misalignment and accommodates thermal expansion. Its compact design also makes it suitable for installations where available space is limited.

Reduced Mechanical Stress

Smooth startup helps reduce mechanical stress and shock during acceleration. By absorbing load shocks, the coupling can also help extend the service life of mechanical seals and bearings.

Wide Temperature Range

Designed for ambient temperatures from -40°C to 80°C, the coupling supports applications across a broad range of industrial environments. Its magnetic transmission design also avoids electromagnetic interference generated by direct electrical coupling between the motor and driven machine.

Technical Specifications

The FTL-BT series covers rated power from 15 kW to 1800 kW. Representative models include:

The listed models use a 1500 rpm, four-pole input configuration. Maximum input speed varies by model, so the complete specifications should be checked when selecting a coupling for a specific drive system.

Industrial Applications

The FTL-BT magnetic coupling can be applied to a range of industrial equipment, including:

• Conveyor belts, bucket elevators, and material conveying systems

• Pumps and compressors

• Air preheaters

• Industrial fans and blowers

• Shredders and crushers

• Pulpers, mixers, and hammer mills

For equipment that requires emergency braking, reduced mechanical stress, and lower maintenance demands, the FTL-BT magnetic coupling provides a drive solution that combines magnetic torque transmission with a dedicated braking function. Model selection should consider rated power, operating speed, installation dimensions, load characteristics, and braking requirements.
