About Self-cooling Magnetic Powder Brake

The magnetic powder brake has a characteristic that the excitation current and the transmission torque are substantially linear. It can transmit a certain torque regardless of the slip, and has the advantages of fast response, simple structure, no pollution, no noise, no impact vibration and energy saving. It is a multi-purpose, high-performance automatic control component. It has been widely used in papermaking, printing, plastics, rubber, textile, printing and dyeing, wire and cable, metallurgy, tablet presses and other unwinding and winding tension control in the coiling and processing industry.

The magnetic powder brake must generate a certain amount of heat during operation. The ideal heat dissipation structure and heat dissipation method can avoid the surface temperature exceeding the standard. General magnetic powder brakes mainly use self-cooling heat dissipation and reasonable structural design. Then, the advantages of self-cooling magnetic powder brakes are as follows:
1. Self-cooling magnetic powder brake adopts aluminum alloy casing with excellent heat dissipation, which has good heat dissipation performance and long service life of magnetic powder.
2. Eliminating the forced cooling water source and water pump, saving printing machinery space and reducing production consumption.
3. The circulating waterway is eliminated to avoid the leakage of cooling water and cause the magnetic powder to sinter.
4. The braking torque is relatively large, the control power is smaller, the structure is simple, and the installation is more convenient.
