Magnetic Powder Brake

Scope of application

Due to the above characteristics of magnetic powder brakes, it has been widely used in papermaking, printing, plastics, rubber, textiles, printing and dyeing, wire and cable, metallurgy and other related winding processing industries for unwinding and winding tension control. In addition, the magnetic powder clutch can also be used for buffer starting, overload protection, speed regulation, etc. Magnetic powder brakes are often used for dynamometer loading and braking of transmission machinery.

Details about Magnetic Powder Brake

working principle

1: Magnetic powder brake is a new type of transmission element that uses magnetic powder as a medium to form a magnetic powder chain to transmit torque when energized. It is mainly composed of inner rotor, outer rotor, excitation coil and magnetic powder.

2: When the coil is not energized, the driving rotor rotates. Due to the centrifugal force, the magnetic powder is thrown on the inner wall of the driving rotor. There is no contact between the magnetic powder and the driven rotor, and the driving rotor is idling.

3: An electromagnetic field is generated after the DC power supply is turned on. The magnetic powder of the working medium forms a magnetic powder chain under the action of the magnetic force line, which connects the inner rotor and the outer rotor, so as to achieve the purpose of transmitting and braking torque.

Magnetic powder brake application
1. Buffer start and stop: use the smooth and constant torque characteristics of the connection to achieve buffer start and stop.
2. For continuous sliding and tension control
3. For torque limiter
4. For high-speed response
5. For power absorption
6. For positioning stop
7. For simulated load
