Magnetic powder clutch brake is widely used, and it is classified as follows: Brake Control, Start-Up This application includes normal start (clutch) and brake functionality (brake). Because the motor is idling, the maximum torque of the motor can be fully utilized when the load is started. As a result, even if the load GD2 or starting resistance is high, it can be started up easily and smoothly without causing significant impact. Furthermore, because the motor is completely idling, it is extremely beneficial to improve the motor’s working conditions and extend its service life. Furthermore, based on the torque characteristics, adjusting the excitation current is all that is required to control the start and braking time, or to change the start and brake process curves.
Application Of Magnetic Powder Clutch Brake
Large transmission equipment, walking cranes, large blowers, axial fans, air compressors, cement kilns, paper machines, rotary impact machines, rolling, rolling machines, wire drawing machines, large textiles, printing and dyeing, and printing are all practical applications. Machinery, as well as the inching and operation of various pieces of industrial machinery.
Selection Of Magnetic Powder Clutch Brake
1. Torque range of operation The magnetic powder clutch’s maximum torque is affected by coil heating, magnetic saturation characteristics, powder life, and mechanical strength. It is capable of absorbing 130% of the theoretical torque. The lower torque limit is determined by the idling torque and torque stability, with more than 50% of the theoretical torque.
2 . The structure type
A coil-type magnetic powder brake with a slip ring has good heat dissipation but is prone to failure and has low reliability. Furthermore, this structure necessitates frequent reverse operation during operation, which is detrimental to bearing life and unsuitable for high-speed transmission systems. The coil-type magnetic powder clutch operates reliably and has a low idling torque. After energization, the torque increases quickly, but the excitation power, volume, and weight are slightly increased.
3. The cylindrical rotor structure size, magnetic powder is uneven, stable performance, suitable for large machinery; cylindrical rotor moment of inertia and small size, suitable for mechanical transmission requiring high sensitivity The rotor has a low moment of inertia and moves quickly, allowing it to be used in high-frequency combinations.
