Magnetic Powder Brakes And Magnetic Powder Clutches Are Used In A Wide Range Of Applications.

Magnetic powder brakes and magnetic powder clutches are used in a wide range of applications, including high-speed extruders for wire and cable equipment, high-speed stranding machines, extrusion lines, shaftless payoffs, single stranders, twisted pairs, and wire cutters. Series production lines, insulation production lines, etc., while pneumatic brakes are also one of the most common brakes in the wire and cable equipment industry.

The magnetic powder brake device is controlled by the tension controller on the unwinding unit of the coating machine according to the tension signal generated by the tension detector detecting the tension of the strip. The magnetic powder brake is more widely used in the automatic pressing of printing, packaging and textile machinery. Flat die cutting machine, automatic paste folding machine, sheetfed offset printing machine, automatic die cutting machine, film laminating machine, slitting machine, paper bag machine, gravure printing machine, cloth inspection machine, textile machine, coating machine, peritoneal machine And metal processing machines and other fields.

The main function of the magnetic powder brake for the coating machine is to transmit a stable tension to the unwinding unit to ensure uniform coating. The magnetic powder clutch controls the tension of the film when it is mounted on the unwinding roller. Its main function is that the sliding torque can be arbitrarily changed by changing the magnitude of the exciting current when the state is tilted, so it does not need to be adjusted as much as mechanical braking. Using high-quality materials, non-magnetic saturated structure and reasonable magnetic circuit design, the product is small in size, large in torque, short in response time, wide in linear range, small in torque return, and high-quality magnetic powder, resistant to wear and tear. Ageing.


    Range between magnetic powder brake and magnetic powder clutch torque

The magnetic powder brake and the magnetic powder clutch can control the torque very conveniently by adjusting the excitation current, and the torque has a good linear relationship with the excitation current, which is proportional to the excitation current in a fairly wide range. The magnetic powder brake and the magnetic powder clutch are torqued. It is established with the establishment of the excitation current and the magnetic field. After a very small non-response time, it starts from zero and rises exponentially.

The torque control range of the magnetic powder brake and the magnetic powder clutch is between the rated torque and the idle torque of the product. The maximum and minimum values of the torque are calculated to confirm whether it is within the controllable range. The maximum speed of the magnetic powder clutch and the magnetic powder brake should be controlled. Below the allowable speed, the magnetic powder brake and the magnetic powder clutch are used in a continuous slip state. The temperature difference between the magnetic powder brake and the magnetic powder clutch body is increased due to the slip heat, and the heat generation during operation must be controlled in the allowable model. The continuous slip power is below.
