How to reverse the rotation of a vacuum cleaner motor?
So far I've tried reversing it's polarity with no success but I looked up the 2 ICs on it's chip and it has a
555 timer and a 7-stage binary counter.
There are only 2 wires running to the engine from the chip so I presume there is no feedback.
Furthermore there is a potentiometer hooked up to both the ICs which regulates the speed of the engine (and no AD convertor as far as I can tell) so the voltage changes the PWM output as the engine is rated 230V.
All ideas are welcome =)
(I can't supply you with pictures right now, sorry)
