Magnetic Powder Clutch, Magnetic Powder Brake Product Characteristics

The excitation current is linear with the torque

The magnetic powder clutch and the magnetic powder brake use the magnetic powder to transmit the torque according to the electromagnetic principle, and the transmitted torque is substantially linear with the exciting current. Therefore, as long as the magnitude of the exciting current is changed, the magnitude of the torque can be easily controlled. Under normal conditions, the excitation current is proportional to the torque it communicates in the range of 5% to 100% of the rated torque.

Stable slip torque

When the excitation current remains unchanged, the torque it transmits is not affected by the differential speed (slip speed) between the transmission member and the driven member, that is, there is no difference between the static torque and the dynamic torque. Therefore, a constant torque can be stably transmitted. If this characteristic is applied to the tension control, the user can accurately control and transmit the required torque by simply adjusting the magnitude of the excitation current, thereby easily and effectively achieving the purpose of controlling the tension of the coil.

Magnetic powder clutch application range

Due to the above characteristics, magnetic powder clutches and brakes have been widely used in papermaking, printing, plastics, rubber, textile, printing and dyeing, wire and cable, metallurgy and other related winding and winding tension control. In addition, the magnetic powder clutch can also be used for buffer starting, overload protection, speed regulation and the like. Magnetic powder brakes are also often used for dynamometer loading and braking of transmission machinery.


Magnetic powder brake and magnetic powder clutch are inseparable

The magnetic powder brake is a magnetic powder chain formed by the electromagnetic attraction between the braking member and the moving member by means of the magnetic powder, and the friction between the working surface and the working surface generates a brake function.
The magnetic powder brake is a multi-purpose, superior performance automatic control component. It has been widely used in papermaking, printing, plastics, rubber, textile, printing and dyeing, wire and cable, metallurgy, tablet presses and other unwinding and winding tension control in the coiling and processing industry. It has the characteristics that the excitation current and the transmission torque are basically linear. 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.
The magnetic powder clutch has a linear relationship between the exciting current and the transmitting torque. It is based on the electromagnetic principle and the use of magnetic powder to transfer torque. It is a multi-purpose, high-performance automatic control component.
