Working Principle Of The Magnetic Powder Brake

1: The powder brake adopts a magnetic powder as a medium, a magnetic particle chain is formed to transmit torque with power on, which is mainly composed of an inner rotor, outer rotor, magnetic coil and magnetic powder.

2: When the coil is not powered, the active rotor rotates, due to the action of centrifugation, the magnetic powder is smashed on the inner wall of the active rotor and there is no contact between the magnetic powder and the driven rotor, the active rotor idling.

3: After the DC power is powered on, the electromagnetic field is generated and the magnetic particle chain is formed by the magnetic particle of the working medium under the action of magnetic lines. The inner rotor and the outer rotor are connected, thus achieving the purpose of transmitting, braking torque.

Applications Of The Magnetic Powder Brake

  1. Buffer start, and stop with the smooth characteristics and the constant torque
  2. Continuous sliding, tension control
  3. Torque Limiter
  4. High-speed response requirement
  5. Power absorption
  6. Positioning stop
  7. Simulated load

Installation And Use Of The Magnetic Powder Brake

The magnetic powder brake operates using DC as its excitation power supply. The drive shaft of a magnetic particle brake should be installed horizontally, with a permissible deviation of +0.03 mm for the mounting of the drive shaft and the axis of the shaft. It is not compatible with radial bearing main power transmission installation methods.

For initial use, the magnetic powder brake should be powered off after 10 seconds of operation, followed by powering on repeatedly to ensure the fluidity and even distribution of magnetic particles. It is crucial not to exceed the normal torque and rotation speed limits during operation, as doing so will significantly decrease the lifespan of the magnetic powder.
