Default Re: Uher Miniline 220V mains drop

I have been rescuing a Uher 263 recently and alarmed at the temperature that the motor reaches. As they is a reasonabl e amount of space I added a 200 ohm TV type mains dropper section strategically placed to allow the heat to rise to such vents as there are. This drops 40v (in series with the mains supply) and has dramatically reduced the motor temperature but not affected performance in any way
