Posted by BobG on March 14, 2008, 7:39 pm Please log in for more thread options Anyone know of a small 3 phase AC motor? Maybe 12V? For experimentation with controller algorithms? Maybe a way to rewind a universal motor? (except how do you convert the commutator to slip rings?)

A little better explanation of exactly what you want to accomplish will probably lead to a more useful answer, but for now you need to be looking into stepper motors and servo motors. There are also chips out there specifically designed to drive those motors. Once you have a better idea what you are looking for, check out some of the surplus houses such as Marlin P. Jones http://www.mpja.com/ . Vaughn Posted by BobG on March 15, 2008, 10:59 am Please log in for more thread options Lets say I want to make a 3 phase variable speed drive. Most of these motors are 6+ HP and use 240V and cost a couple hundred bux and you'll get killed or go broke while trying to get your software controlled speed control debugged. Now if I could put the shrink ray on that bad boy and take him down to 12V all around, I wouldnt be afraid to hook an avr and three half bridges to it and start programming. Compri?

Make one from an automotive alternator - it is a 3 phase motor inside, with electromagnet core instead of being an induction motor. -- Posted via a free Usenet account from http://www.teranews.com Posted by Ulysses on March 15, 2008, 6:05 pm Please log in for more thread options <clare at snyder dot ontario dot canada> wrote in message > wrote: > > >Lets say I want to make a 3 phase variable speed drive.

Let's see, you'd probably have to eliminate the diodes that keep it from draining the battery when it's not charging... > > -- > Posted via a free Usenet account from http://www.teranews.com > Similar Threads Posted Single Phase Backup Generator to Three Phase Mains Supply?
