I managed to persuade an Arduino to excite and measure the position of a resolver on a servo and use that to produce the 6x PWM signals needed for an IRAMS10UP60. http://youtu.be/oyeJfNg3NfQ I can't claim that it worked especially well, the Arduino can't really handle more than 1kHz excitation, which limited the commutation speed. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Want excitement? Manually upgrade your production database. When you want reliability, choose Perforce. Perforce version control.
