The rated voltage of the magnetic particle clutch brake is DC24V, and the normal torque is 1Nm ~ 400Nm. The main torques of ATO magnetic particle brake are 6Nm, 15Nm, 25Nm, 50Nm, 50Nm, 100Nm, 200Nm, 400Nm.It utilizes the characteristics of magnetic particle to transfer torque, provided that the current is supplied. After a number of authoritative technical tests and experiments, it has been found that the relationship between the exciting current and the transmitted torque is basically linear. Therefore, it seems to be very simple and convenient to adjust the torque of the magnetic particle clutch brake. As long as the magnitude of the exciting current is changed, the torque of the magnetic particle clutch brake can be easily adjusted. In addition, adjusting the torque of the magnetic particle clutch brake usually requires a tension controller (manual or fully automatic). The tension controller outputs a controllable DC0 ~ 24V or 0 ~ 4A for driving the magnetic particle clutch brake, thus realizing the constant tension control of the winding/unwinding process.
