Default Re: Philips N4510 reel motor

A little more on this....

There are some stakes (formed with a punch) around the spindle. I carefully drilled these with a 1.5mm bit and found they retain a washer over the bearing. Under it was a lot of Evil Goo from the old drive belt, which was why it was mechanically stuck. Whether that caused the electrical problems I don't know.

You can press the spindle out from the bottom (commutator) end. The commutator is a separate part, then hanging on the winding wires. NEVER press the spindle from the top (drive) end, you will force the commutator away from the windings and break connections. Whether that was done to this motor at some point I don't know, it's possible it's been apart before.

With the spindle pressed out, the winding assembly (ironless rotor) is loose but it will not come out. It's catching on the field magnet. I cannot work out how it was assembled, and thus how to dismantle it. Does anyone know?
