Its a 17-yo Sharp microwave combi-oven which does a good
job as a mini-oven because it has an upper and a lower grill
element, so heats up quickly.
A few days ago there was a lot of graunching noises and the turntable
no longer turns.
I have removed the synchronous motor and the gears are all fine.
Turning the spigot with pliers rotates the motor itself, I can hear it.
It's marked AC220-240V 2.5.3 RPM 3/2.5Watts.
My multimeter says the contacts are 14.77 Kohms and if I connect
direct to the mains it is dead, not even a buzzing.
This place sells them :-

But I'm not paying £102, when they should be obtainable for about
10 to £15.
Part is marked CHINA GPS Corp ST-16 synchronous motor

There is a 2nd hand one on ebay for £10, but that might be dead too.
An Amazon site has them for about £45. Still too much.
Any ideas who else might sell them ?.

Microwave oven motors are pretty much universal. Rotation speed varies a bit but doesn't matter at all.
