microwave turntable motors (250v)

[Kirkpatrick]

I'm using one for driving a 3rpm spindle in a "flame-imitation-type" electric fire - the flame effect obviously must "go upwards". Problem is that these motors are bi-directional and often need to be turned off/on to correct the direction of rotation. Any suggestions please as to how to make it rotate in the same direction every time.

motors generally use a capacitor "kick" to get them to spin - and I thought it was part of the design - It's a bit like the light in the fridge .... does it or doesn't it switch off ...

I've never noticed my microwave cooling things down - so just assumed that it always spun the same way .....

but I can't think of very many devices that use real inductive AC motors - anything delivering power tends to be rectified DC

I have no answer - but I'm interested.
would something like a flourescent starter always deliver the same initial polarity?

my old record player was an induction ac motor - but it never went the wrong way -

I seem to remember that mum's electric alarm had a little knob on the back you flicked to start it going - presumably for this very reason

They are called shaded pole motors ,they dont need capacitors to get them going unlike other single phase motors that use a capitor which we called split phase ,ime going back 25 yrs and the old memory might not be so good so check up on me
all the best
