My clutch won't stay engaged when it gets hot

This snippet is from Ogura's full length troubleshooting online video. In this 30 second video segment, we show how overheated/degraded magnet wire can prevent full torque generation in the clutch or brake.

As coils heat up, the insulation coating on the magnet wire can break down.

This causes electrical leakage and higher amp draw in the coil and less torque available in the clutch or brake.

A coil at room temperature may appear to be normal, but after it heats up, it may have a higher amp draw.

To test for this, connect the clutch or brake to the power supply for approximately two hours.

If there is a significantly lower ohm reading the unit would need to be replaced.
