The magnetic particle brake is an automatic control element that uses magnetic particle to transmit torque based on the electromagnetic principle. It has a basically linear relationship between the excitation current and the transmitted torque. It can transmit a certain torque regardless of the slip. It has a fast response speed, simple structure, and superior performance. It is widely used in various machinery for different purposes of braking, loading, and unwinding tension control in the winding system.
The machine-mounted 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, and durability. It can be used for braking (brakes) of various machines, as well as for tension control and torque measurement loaders of various systems. The machine-mounted magnetic particle brake is widely used in rubber, packaging machines, plastic processing, coating machines, printing, papermaking, wires and cables, etc. in unwinding and winding tension control occasions. It is a commonly used transmission equipment for modern industrial production machinery.
The machine-mounted magnetic particle brake is an indispensable transmission device for the unwinding and tension control system of long-sized 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 to achieve constant tension.
Selection requirements for machine-mounted magnetic particle brake
- When selecting, consider whether the torque can meet the needs of the tension control system.
- The heat generated during operation should not exceed the allowable continuous slip power of the model used.
- The selection is based on the comprehensive matching of machinery to determine how much torque is required to meet the load requirements, and whether the installation method and space meet the requirements.
- The selection of single-axis machine-mounted magnetic particle brake is generally based on the large torque to be transmitted, and the slip power is selected based on the speed. Pay attention to ensure that the actual slip power cannot be greater than the allowable slip power of the magnetic particle clutch.
Conclusion
The machine-mounted magnetic particle brake has the characteristics of speed response, durability, simple structure, energy saving and environmental protection. It is widely used in the unwinding and tension control systems of printing machines, packaging machines, textile machines, wires and cables, printing and dyeing, rubber and other industrial machinery in the field of industrial machinery.
