Default rek o kut k33h

i am looking a buying a rek o kut k33h with the Papst synchronous motor, made in West Germany. its 110v and 50-60hz

being in sweden the voltage is at 220, i dont think the voltage is an issue bbut will this run slower in europe

hope you can help

Voltage differences won't alter the rotional speed of a synchronous motor but frequency differences will. If its specified at 60 hz then running it on 50 will see the speed drop proportionally, and vice versa.

Is that what you mean

I see you mention its specified as 110 v. That would overheat on 220-240 volts.

i have a transformer for the voltage

the motor states its 50-60 cycles will this run the same speed at 110 on 50hz

The rotational speed depends absolutely on the frequency. Athough it will run on either 50 or 60 hz the speed will be different on each.

Its a turntable from a quick google search. Does it come with "control electronics" that power the motor from a quartz reference and high voltage amplifier ? The pictures I saw have a small box at the side that looks as though it might. That makes it independent of the mains frequency. Or a different sized pulley for 50 or 60 hz use if run of mains directly.

The speed of that motor is locked to the mains. So if the turntable was designed to run on 60 hz it will not work on 50 hz. It would be slow.

(The motor itself will run on a wide range of frequencies but that is no good to you if the turntable drive system is built specifically for just one set frequency)
