The Difference Between The Extension Of The Shaft Base Type Magnetic Powder Brake

When the magnetic powder brake is working, under the action of the magnetic field, the magnetic powder chain is continuously formed, and the heat generated by the continuous breaking and the heat generated by the friction between the magnetic powder and the rotor and the stator are relatively easy to dissipate. The manufacturer of the Tailing magnetic powder brakes has designed and manufactured a magnetic powder brake with a heat sink to make it easy to dissipate heat. Ensure that the magnetic powder brake is running, which not only meets the braking torque required by the machine, but also balances the heat generation and heat dissipation of the motion.

The rated voltage of the extended shaft magnetic powder brake is DC24V, which can be used at 5r/min. It helps to increase the heat capacity by adding compressed air to the gap to dissipate heat. In order to improve the cooling effect, an axial fan can also be arranged at one end of the driving body; note that the cooling air must pass through the air filter to ensure no oil, no water, and dry air. There is a small gap between the magnetic coil of the extended magnetic powder brake clutch and the transmission unit, so a large magnetic power is required. The size of the coil and the fuselage is also relatively increased, but the flywheel moment of the input shaft required for both is correspondingly reduced.

The base magnetic powder brake is an excellent automatic control element. It uses magnetic powder as the working medium and uses the excitation current as the control means to achieve the purpose of controlling braking or transmission torque. Its output torque has a good linear relationship with the excitation current and has nothing to do with the speed or slip, and has a fast response. The structure is simple and so on. The base magnetic powder brake is widely used in the automatic tension control system of the winding device for printing, packaging, paper and paper processing, textile, printing, wire, cable, rubber and leather, metal foil strip processing.

Due to its inherent structural characteristics, the magnetic powder brake determines that the non-response time, torque rise time and torque drop time of the product are extremely short. This characteristic determines that the magnetic powder clutch and the magnetic powder brake can be applied to frequent start and stop, reversing. Application. Special needs can be further optimized by mechanical parts and improved loading power to increase response speed.
