Magnetic Particle brake is a new transmission element based on electromagnetic principle, using magnetic powder as medium, and forming magnetic Particle chain to transmit torque when powered.
Magnetic Particle brake can easily control the torque within the range of 5% to 100% of rated torque by changing the magnitude of excitation current, and the excitation current is in direct proportional linear relationship with the torque it transmits.
Magnetic Particle brake is a new transmission element that uses magnetic Particle as medium and forms magnetic Particle chain to transmit torque when powered. It is mainly composed of inner rotor, outer rotor, excitation coil and magnetic Particle. When the coil is not powered, the active rotor rotates. Due to the centrifugal force, the magnetic Particle is thrown on the inner wall of the active rotor.
There is no contact between the magnetic Particle and the driven rotor, and the active rotor runs idly. After the DC power supply is turned on, an electromagnetic field is generated, and the working medium magnetic Particle forms a magnetic Particle chain under the action of magnetic lines of force, connecting the inner rotor and the outer rotor, thereby achieving the purpose of transmitting and braking torque.
Precautions For The Use Of Magnetic Particle Brakes
- The surface temperature of magnetic Particle brakes in normal operation, especially newly installed magnetic Particleclutches and brakes, should not exceed 80 degrees Celsius, water-cooled brakes should not exceed 90 degrees Celsius, and forced air-cooled brakes should not exceed 60 degrees Celsius.
- Before the first use of the magnetic Particle brake, pass 30% of the rated current, run for 10 seconds, then turn off the power and turn on the power again, repeat several times to ensure the fluidity and uniform distribution of the magnetic Particle
- The magnetic Particle brake cannot be used at excessive torque or speed, otherwise the life of the magnetic Particle will drop sharply, or Particle leakage or jamming will occur.
- If the magnetic Particle is damp, the performance will become unstable, so be careful not to let oil or moisture invade the interior of the magnetic Particle brake. Especially when installed in a gearbox, oil will penetrate the interior through the shaft, so it must be completely sealed with a film.
Conclusion
Magnetic Particle brake has the advantages of fast response speed, simple structure, no pollution, no noise, no impact vibration and energy saving. During daily use, attention should be paid to maintenance and repair to extend the service life of the equipment.
