Description of magnetic particle brake
the magnetic force and magnetic attraction produced hardening phenomenon in continuous sliding between the torque transmission.
the magnetic characteristics of constant torque characteristic of magnetic particle stability superior good, and powder between binding force stability, sliding torque is very stable, and the relative rotation number of Never mind lasting constant torque.
The output torque and excitation current powder showed a good linear relationship with the speed or slip, and has fast response speed, simple structure (1) control torque control torque and high precision is very wide, and the control precision is high, transmission torque and exciting current into the correct proportion, can achieve high control precision.
It uses magnetic powder as the working medium, the excitation current as control means to control the braking torque or purpose
The magnetic particle brake is composed of a transmission unit (an input shaft) and a driven unit (an output shaft). The space between the two units is filled with granular magnetic particles (equal to about 40 microns). When the magnetic coil is not conductive, torque from the drive shaft will not pass on the driven shaft, but if the electromagnetic coil is energized
