Hello,
I've fond on Ebay a Premotec motor without connection circuit.
Anybody have a schematic of this circuit?
Can you help me?
Ciao

The cct I put in the thread is what I took from my notes on my own Rega Planar 3 some years ago (220 V 50 Hz).
Your first Pic you posted I recognise as being the 110 60 Hz connection. Beware, if you use the motor in the pic the pulley more then likely smaller then 220 V 50 Hz version and even if wired for 220 V it will run slow. Freq, not volts control AC motor speed... Hence the different pulleys for 50 and 60 Hz.
This may be the reason it is for sale? 😉
Not sure about the other 2 pics. I guarantee my cct will work on 220 v. Speed is dependant on pulley being correct for your countries frequency.
