Inverting rotation of a VPi record cleaner

[m.parigi]

I own a VPI 16.5 record cleaning machine and I've noticed that I get far better results in cleaning my records when I scrub them both direction, as opposed to the "standard" rotation sense of the machine.

For some arcane reason (I think I read something about it somewhere, I just don't remember where) it looks like I'm able to remove far more "ticks" when I stop the machine and I manually scrub in the opposite direction.

So, here's my question: is it possible to change the rotation sense of an AC motor (electrically, I mean)? Why does an electric motor turn in a given direction, anyway? 😕

My ideal solution would be a switch that would allow me to make the platter turn either direction. Is it something doable?

Hi m.parigi,
http://www.google.be/search?q=direction+of+ac+motor&ie=UTF-8&oe=UTF-8&hl=nl&meta=
could be a good start.
As we don't know which motor is in there, it's difficult to answer.
Anyway, your thread is on top again. 😉

Hi,

A switch inversing the polarity of the motor should do it as it is likely to be an AC unit.

Cheers,😉

fdegrove, I'm not sure how to implement that, hence the question!
The motor is definitely an AC motor running on 220V. I've experimented inverting the live and neutral wires, but the *******' motor will keep turning in the same direction.

What wires/connections should I look for?
Thanks,
Maurizio

The 17F has reversible motor drive as standard (you can buy this type of motor for a 16.5 as an option).
