Magnetic Particle Brake:structure & 4 major characteristics

The magnetic Particle brake is based on the electromagnetic principle and uses magnetic Particle to transmit torque. It has a basically linear relationship between the excitation current and the transmission torque, and can transmit a certain torque regardless of slip.

Magnetic Particle brake has fast response speed, simple structure and superior performance. It is a widely used automatic control component and is used for braking, loading and unwinding tension control in winding systems for different purposes in various machinery.

What is a frame-mounted magnetic Particle brake?

The frame-type magnetic Particle brake has the advantages of simple structure and control, high-speed response, high control accuracy, wide torque control range, low power consumption, low operating noise, durability, etc. It can be used for braking (braking) of various machines. , and can also be used as loaders for tension control and torque measurement in various systems. Base-type magnetic Particle brakes are widely used in unwinding and rewinding tension control situations such as rubber, packaging machines, plastic processing, coating machines, printing, papermaking, wires and cables, etc. They are commonly used transmission equipment in modern industrial production machinery.

The single-axis base magnetic Particle brake is an indispensable transmission device for the unwinding and tension control system of long-size materials such as paper, wires, and various films. It transmits torque through magnetic Particle and can be freely controlled and adjusted through the tension controller. Achieve constant tension.

The single-axis base type magnetic Particle brake has the characteristics of speed response, durability, simple structure, energy saving and environmental protection. It is widely used in printing machines, packaging machines, textile machines, wires and cables, printing and dyeing, rubber and other industrial machinery in the field of industrial machinery. Unwinding and tension control system.

Three selection requirements for frame-mounted magnetic Particle brakes

The selection of frame-mounted magnetic Particle brakes is generally based on the large torque that needs to be transmitted, and the slip power is selected based on the rotation speed. Pay attention to ensure that the actual slip power cannot be greater than the allowable slip power of the magnetic Particle clutch.

  1. When selecting, consider whether the torque size can meet the needs of the tension control system.
  2. The heat generated during operation should not exceed the allowable continuous slip power of the model used.
  3. The selection is based on the comprehensive mechanical matching to determine how much torque is needed to meet the load requirements, as well as the installation method, whether the space meets the requirements, etc.


As a commonly used braking device, magnetic Particle brake has large braking torque, good control performance and protection performance. Magnetic Particle brakes are widely used in automatic tension control systems for winding devices in printing, packaging, papermaking and paper processing, textiles, printing, wires, cables, rubber leather, metal foil processing, etc.
