How To Control The Surface Temperature Of The Magnetic Powder Clutch?

Magnetic powder brake surface temperature control methods: generally there are air-cooled cooling, water-cooled cooling and heat sink cooling. The torque control range of the magnetic powder clutch is very wide, and the control accuracy is high. The transmission torque and the excitation current are in the correct ratio, and high-precision control can be achieved. The surface temperature during continuous operation should be controlled within the limits. The temperature continues to rise with the running time. At this time, it should be noted that the temperature rise of the magnetic powder clutch needs to be controlled within 80 degrees, otherwise it will affect its performance and cause the durability of the magnetic powder brake to be greatly reduced.

The service life of the magnetic powder is directly affected by the operating time, speed, surface temperature, and frequency of the magnetic powder brake. Since the interior of the magnetic powder brake is strong, once it is in operation, the temperature will be generated inside and on the surface. The operation of the magnetic powder clutch will generate heat, and some heat dissipation measures are required for long-term operation. After the magnetic powder clutch stops running, the water supply stop time varies depending on the relationship between room temperature and water temperature. Especially when the temperature difference between room temperature and water temperature is about 10°C, please stop within 5 minutes. In order to prevent condensation of magnetic powder clutches at night, magnetic powder clutch manufacturers should keep the temperature difference between water temperature and room temperature below 10℃.

The magnetic powder clutch will also generate heat during normal use, but the temperature of the complete heat dissipation device will not be too high. Due to the existence of slip in the normal operation of the magnetic powder clutch, the magnetic powder in the working gap produces friction and heat, and the bearing also generates heat due to friction. These heat will cause the temperature of the magnetic powder brake, clutch magnetic powder, coil, bearing, etc. The increase will subsequently affect its surface temperature. Magnetic powder clutches are widely used in automatic tension controller systems for winding devices such as wire, cable, packaging, printing, paper and paper processing, textile, rubber leather, and metal foil belt processing.
