About magnetic powder clutch, read this article at a glance


The magnetic powder clutch is a combination of a transmission unit (input shaft) and a driven unit (output shaft). The space between the two groups of cells is filled with granular magnetic powder (about 40 microns in volume). When the magnetic coil is not conductive, the torque will not be transmitted from the transmission shaft to the driven shaft. However, if the coil is electromagnetically energized, the magnetic powder will be attracted by the magnetic force to cause hardening, and the torque will be transmitted between successive slips .

Magnetic powder clutch is an automatic control element with superior performance. It uses magnetic powder as the working medium and the exciting current as the control means to achieve the purpose of controlling braking or transmitting the transition. Its output transition has a good linear relationship with the excitation current and has nothing to do with the speed or slip, and has the advantages of fast response speed and simple structure.

The characteristics of the magnetic powder clutch are as follows:

(1) High-precision torque control
The control range of the torque is very wide, and the control accuracy is high. The torque and the exciting current are transmitted to the correct ratio, which can achieve high-precision control.

(2) Excellent durability and long life
Super heat-resistant, abrasion-resistant, oxidation-resistant, and corrosion-resistant superalloy magnetic powder is adopted for long life.

(3) Constant torque characteristics with superior stability
The magnetic properties of the magnetic powder are good, and the binding force between the particles is stable. 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
Excellent heat dissipation effect and uniform thermal deformation cooling structure, coupled with the high heat resistance of magnetic powder, allow large connection and braking power and sliding power, can smooth sliding operation without causing vibration. (5) The connection is smooth, and the impact during the non-impact connection is extremely small, enabling smooth start and stop without impact. And the resistance torque is extremely small, which will not cause useless heat generation.

(6) Suitable for high-frequency operation with agile and fast response and special heat dissipation structure, suitable for high-frequency operation.

(7) Lightweight, maintenance-free and long life
The type is simple and lightweight, using high temperature resistant coils and special grease bearings, and abrasion-resistant special treatment is applied to the abrasion-prone armature to prolong the service life.

Magnetic powder clutches are widely used in automatic tension control systems for coiling devices such as wires, cables, packaging, printing, paper and paper processing, textiles, rubber leather, and metal foil tape processing.
