How can we improve? Okay , my magnetic clutch I believe is bad. One of them connects to the negative battery terminal, and the other goes to the positive side. When a magnetic field is applied by a coil to the powder, it forms chains connecting the disc and rotor. This field (flux) overcomes the air gap between the clutch rotor and the armature. 1. Many converting applications and web tension processes require adjustable torque while maintaining a dust-free environment, making magnetic particle clutches an ideal solution. 2. Difference between Bilstein B4 Vs B6 Ride Quality, Difference between Bosch Vs Ngk Spark Plugs, Inspect all connections and wiring in the circuit for signs of damage or corrosion, Test the operation of the clutch switch and sensor with a multimeter, Clean any dirt or debris from the contact points on the clutch itself, Ensure that they are free of rust or other corrosion before proceeding, Use a magnet to check for proper alignment of the clutchs north and south poles, Adjust as necessary so that they are properly aligned again.
