What Are The Causes Of The Magnetic Powder Brake And Clutch Jam?

The magnetic powder clutch uses magnetic powder to transmit torque. It transmits torque in a linear relationship with the excitation current. 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. Magnetic powder clutches are widely used for buffer starting, speed regulation, overload protection, and tension control for winding in winding systems. It is a multi-purpose, high-performance automatic control component.

        The causes of the magnetic powder and clutch jam are bearing damage, magnetic powder leakage, insufficient precision, and insufficient concentricity. The fixing bolts are loose, the inferior magnetic powder is used or the sealing amount is too small, and the magnetic powder brake clutch is not installed correctly. Let's talk about it in detail:

1. Bearings are installed at the output/input ends of the magnetic powder clutch. Insufficient lubrication will result in bearing damage, or may be stuck due to quality problems such as prolonged work and rupture;

2. magnetic powder, magnetic powder clutch transmission torque is based on magnetic powder, magnetic powder will slowly flow to the bearing at the input / output ends, because the magnetic powder is a tiny granular material, it will easily penetrate into the bearing, and Jam the bearing;
3. the lack of concentricity, due to defects in the manufacturing process, technology, precision, etc., resulting in uneven output torque or stuck;

4. The magnetic powder clutch is stuck because the magnetic powder is insufficiently sealed, the inferior magnetic powder is used, the fixing bolts are loose, the installation is incorrect, and so on.
