Right Shane, actually I think it you boil all the comments down, we are close. Brushless is not straight forward controls at all and there are methods and schemes to follow. Seems to me if you resonate with the motor switching electronics the motor will just wiggle back and forth. Having said that, once you get the motor running, you may be able use the pwm, but watch out for modal ressonate frequency to the switching scheme, of which I do not have the understanding to determine without the knowledge of the motor design itself.

You're not measuring a motor winding. I say if you have a red and black wire, hook that up to +5 VDC and see if she spins. -B _______________________________________________ Triangle, NC Embedded Computing mailing list To post message: [email protected] List info: http://mail.triembed.org/mailman/listinfo/triembed_triembed.org TriEmbed web site: http://TriEmbed.org To unsubscribe, click link and send a blank message: mailto:[email protected]?subject=unsubscribe
