Magnetic Powder Clutches Are Now Widely Used In A Wide Range

Magnetic powder clutch (magnetic powder brake) is used for tension control, overload protector, torque loader, etc. such as printing machine, paper machine, winder, wire drawing machine, metal calender, film processing machine, textile machinery, etc.; Engine, hydraulic reducer, etc. load device for loading experiments.

The magnetic powder clutch transmits torque according to the electromagnetic principle and using magnetic powder. It has a linear relationship between the excitation current and the transmission torque. It can transmit a certain torque regardless of the slip, and has the advantages of fast response, simple structure, no pollution, no noise, no impact vibration and energy saving. It is a multi-purpose, high-performance automatic control component. Magnetic powder brakes are widely used for braking, power test loading, and unwinding tension control for various purposes in various machines. Magnetic powder clutches are widely used for buffer starting, overload protection, speed regulation, and tension control for winding in winding systems.

The slip phenomenon of the moving surface of the magnetic powder clutch occurs in the friction mode, but it does not occur here, and the connection sound is not emitted, so the operation is quite quiet. The magnetic powder clutch uses the magnetic powder with excellent heat resistance and is ideally used. The cooling method can be used with peace of mind even in the case of a too severe continuous sliding operation. Since the static friction coefficient and the dynamic friction coefficient are almost the same, the magnetic powder clutch does not oscillate when fully connected, and can be used to increase or decrease the load.

When the coil is not energized, the active rotor rotates. Due to the centrifugal force, the magnetic powder is clamped on the inner wall of the active rotor. There is no contact between the magnetic powder and the driven rotor. The active rotor is idling, and the magnetic powder brake generates electromagnetic field after being connected to the DC power supply. The working medium magnetic powder forms a magnetic powder chain under the action of magnetic lines of force, and connects the inner rotor and the outer rotor to achieve the purpose of transmitting and braking torque.

Magnetic powder brakes are now widely used in papermaking, printing, plastics, rubber, textile, printing and dyeing, wire and cable, metallurgy, tablet presses and other related winding and winding tension control, magnetic powder brakes in the power supply situation The new transmission component that forms a magnetic powder chain to transmit torque is mainly composed of an inner rotor, an outer rotor, an excitation coil and a magnetic powder.
