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 transmitted torque. It can transmit a certain torque regardless of the slip. It has the advantages of fast response speed and simple structure. It is a multi-purpose, high-performance automatic control component.
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 loaders for tension control and torque measurement of various systems.
The single-axis 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. The single-axis machine-mounted magnetic particle brake has the characteristics of speed response, durability, simple structure, energy saving and environmental protection.
The selection of single-axis machine-mounted magnetic particle brake is generally based on the maximum 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.
Selection requirements for machine-mounted magnetic particle brake
- When selecting, consider whether the torque size can meet the requirements 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 the machinery to determine how much torque is required to meet the load requirements, and whether the installation method and space meet the requirements, etc.
Conclusion
Machine-mounted magnetic particle brakes are widely used in rubber, packaging machines, plastic processing, coating machines, printing, papermaking, wires and cables, etc. in unwinding and winding tension control occasions. They are the most commonly used transmission equipment for modern industrial production machinery.
