Magnetic powder brake working principle

The magnetic powder brake uses magnetic powder as a medium, and a new transmission component that forms a magnetic powder chain to transmit torque under energization is mainly composed of an inner rotor, an outer rotor, an excitation coil and a magnetic powder.

When the coil is not energized, the active rotor rotates. Due to the centrifugal force, the magnetic powder is clamped on the inner wall of the active rotor, and there is no contact between the magnetic powder and the driven rotor, and the active rotor idles.

After the DC power is turned on, a magnetic field is generated, and the magnetic powder of the working medium forms a magnetic powder chain under the action of the magnetic force line, and the inner rotor and the outer rotor are coupled to achieve the purpose of transmitting and braking torque.


It is widely applied in printing equipments, paper industry, bag-making machines, wire and cable machinery,coil machinery,wire winding machines,strapping bag machinery, laminating machines,textile machinery, weaving-dimensional machinery, woodworking machinery, extruders, specialized machinery and so on.
