The miniature magnetic powder clutch is a transmission component developed in the past ten years. Due to its superior controllability, it has been widely used in modern industry. And the magnetic powder clutch is a multi-functional transmission member, which is used by various machines for torque transmission, braking, overload protection and the like.

The working mechanism of the Tianji brand miniature magnetic powder clutch is that when the current passes through the excitation coil and establishes the magnetic field, the magnetic powder forms many small magnetic powder chains in the working gap. Under the action of the magnetic field, the magnetic powder chain is evenly distributed according to the radial direction of the coil. The magnetic powder chain is continuously formed and fractured, but there is always a certain amount of magnetic powder chain transmitting the force. The magnetic powder magnetized in these magnetic powder chains is perpendicular to the normal direction of the two pole faces, and the adjacent magnetic powder particles are mutually squeezed. Pressing, the two ends of the magnetic powder chain are subjected to a normal pressing force perpendicular to the two pole faces. When the brake rotor rotates relative to the stator, the magnetic powder chains are pulled in opposite directions, causing relative movement between the magnetic powders or There is a tendency to move relative to the friction, resulting in a braking torque. Miniature magnetic powder clutches must be installed in a dry and ventilated environment.
