Tension Magnetic Powder Brake for Rewind and Unwind Machine

Introduction:
Hollow Shaft Shell Rotating Magnetic Powder Brake

Magnetic powder brake (commonly known as magnetic powder brake, natural cooling type) is based on electromagnetic principles and uses magnetic powder to transmit torque. It has the characteristic that the excitation current and the transmission torque are basically linear. It can transmit a certain torque regardless of slip, and has the advantages of fast response, simple structure, no pollution, no noise, no impact and vibration, and energy saving. It is a multi-purpose automatic control component with superior performance.

It has been widely used in unwinding and winding tension control in papermaking, printing, plastics, rubber, textile, printing and dyeing, wire and cable, metallurgy, tablet press and other related winding processing industries.

Magnetic Powder Brake HJP-B1 :

The hollow shaft outer shell rotary type magnetic powder brake has a heat-dissipating method of natural cooling, which rotates the periphery to improve heat dissipation performance and improves the heat capacity of the model. The characteristics of the product are as follows:

(1) High-precision torque control The torque control range is very wide, and the control precision is high. The transmission torque and the exciting current are in the correct ratio, which can realize high-precision control.
(2) Superior durability and long life. Super alloy magnetic powder with super heat resistance, wear resistance, oxidation resistance and corrosion resistance is used, and the life is long.
(3) Stable constant torque characteristics. The magnetic characteristics of the magnetic powder are good, and the binding force between the particles is stable, and the sliding torque is very stable. It has no relationship with the relative number of revolutions and can maintain a constant torque for a long time.
(4) Continuous sliding operation use Excellent heat dissipation and uniform thermal deformation cooling structure, coupled with the high heat resistance of magnetic powder, allow connection and braking power and high sliding power, smooth sliding operation, without causing vibration.
(5) Smooth connection without impact The impact during connection is extremely small, and it can start and stop smoothly without impact. Moreover, the resistance torque is extremely small and will not cause useless heat generation.
(6) Suitable for high frequency operation, quick response and special heat dissipation structure, suitable for high frequency operation.
(7) Lightweight, maintenance-free, and long life. The model is simple and lightweight, using high-temperature resistant coils and special grease bearings, and special wear-resistant treatments are applied to the armature that is prone to wear to extend the service life.
