Magnetic Particle brake is a braking device that fills the working gap between the stator and the rotor with magnetic particle, and transmits power and motion by means of the binding force between the magnetic particles generated by electromagnetic attraction and the friction between the magnetic particles and the working surface, and can control and adjust the torque.
Simply put, the magnetic particle brake is based on the electromagnetic principle and uses magnetic particle to transmit torque. The device has a fast response speed, simple structure, no pollution, and no noise. It is mainly used in mechanical transmission systems that require braking and control systems that require speed regulation, tension control, test loading, etc.
Functional Characteristics Of Magnetic Particle Brake
- High-precision torque control. The torque control range is very wide and the control accuracy is high. The transmitted torque and excitation current are in the correct proportion, which can achieve high-precision control.
- Excellent durability and long life. It uses super alloy magnetic particle with super heat resistance, wear resistance, oxidation resistance and corrosion resistance, and has a long life.
- Super stable constant torque characteristics. The magnetic properties of magnetic particle are excellent, and the bonding force between the particle particles is stable. The sliding torque is very stable and can maintain a constant torque for a long time regardless of the relative number of revolutions.
- Continuous sliding operation. The heat dissipation effect is excellent and the cooling structure with uniform thermal deformation is adopted. In addition, the high heat resistance of magnetic particle allows large connection and braking power and sliding power, and can slide smoothly without causing vibration.
- Smooth connection and no impact. The impact during connection is extremely small, and it can start and stop smoothly without impact. In addition, the resistance torque is extremely small, and no unnecessary heat is generated.
- Suitable for high-frequency operation. The quick response and special heat dissipation structure are suitable for high-frequency operation.
- Lightweight, maintenance-free, and long life. The type is simple and lightweight, using high-temperature resistant coils and special grease bearings, and applying special wear-resistant treatment to the armature that is prone to wear to extend the service life.
Conclusion
The magnetic particle brake is a multi-purpose, high-performance automatic control component. It has been widely used in unwinding and rewinding tension control in papermaking, printing, plastics, rubber, textiles, printing and dyeing, wire and cable and other related winding processing industries.
