A couple of my Racestar/Ollin 5065 motors are making weird clicking sounds, so I think they need a bearing change. Does anybody know the size/model of the two stacked bearings that sit between the sleeve and hall sensor, at the rear of the motor?
Most of mine have the same clicking sound, I don’t know what it’s from, but it’s never caused a failure. I thought it was loose magnets, but no magnets are loose. I’ve just accepted clicking as a hallmark of Racerstar motors.
They’re not bad for how light and cheap and small they are, so
Good to know this is a common issue that doesn’t case failures. It would be interesting to find out the exact cause though. The rear bearings look really undersized so I assumed it might be them @b264?
Check that you haven’t got a short to ground from one of your phase wires. Check the screw that goes into motor near where the cables leave the body of the motor.
