Principle and model of magnetic powder clutch for slitting machine?

The principles and models of magnetic powder clutch are: magnetic powder clutch, shell rotating magnetic powder clutch, hollow shaft magnetic powder clutch, miniature magnetic powder clutch and miniature magnetic powder clutch. Magnetic powder clutch for resolver depends on your requirements. See "Dongguan Machine Reducer" for details.

Principle of magnetic powder clutch: It is formed by merging transmission unit (input shaft) and driven unit (output shaft). The space between the two groups of units is filled with granular magnetic powder (about 40 microns). When the magnetic coil

When there is no electricity, the torque will not be transmitted from the driving shaft to the driven shaft, but if the coil is electromagnetically energized, the magnetic force will attract the magnetic powder to harden, and the torque will be transmitted between successive slides.

HELISTAR magnetic powder clutch/brake characteristics

(1) high-precision torque control

The torque control range is wide and the control accuracy is high. The ratio of transmission torque to excitation current is correct, and high precision control can be realized.

(2) good durability and long service life

Super alloy magnetic powder with heat resistance, wear resistance, oxidation resistance and corrosion resistance is adopted, and the service life is long.

(3) constant torque characteristic and good stability

Magnetic powder has good magnetic gas characteristics, the binding force between powder particles is stable, the sliding torque is very stable, and it can maintain a constant torque for a long time regardless of the relative number of revolutions.

(4) continuous sliding operation

Good heat dissipation effect and uniform thermal deformation cooling structure, coupled with the high heat resistance of magnetic powder, allow large connecting and braking power and sliding power, so that the sliding operation is stable and free.

Cause vibration.

(5) Smooth connection and no impact

The impact during connection is very small, and it can be started and stopped smoothly without impact. Moreover, the resistance moment is extremely small and will not cause useless heat.

(6) Suitable for high frequency operation

Fast response and special heat dissipation structure, suitable for high frequency operation.

(7) light weight, maintenance-free and long service life

Simple and lightweight, using high-temperature resistant coils and special grease bearings, the armature which is easy to wear is treated with special wear resistance to prolong its service life.
