BSATOM
1 W
I got this controller just to modify. It came today(link 1). It has 100v 330w fets with 7.0mOhm on resistance(MXP1007AT) and 100v Chang caps as expected. What I did not expect was the 15 FETS inside. This controller is rated at 72v 500w. 6 of these fets could easily handle that rating. It seems that I can solder the shunts up and go go go. I might put the 4110 fets in there anyway, for the 40 watts more per device and almost half the on resistance.
Another cool thing is that the main chip is a GPM8F311A (link 2 is to a download page). When looking at page 94, it appears that I can directly drop in the GPM8F3132A and have sine wave output to the motor. I need to read more to see if any other circuitry would be needed for the sine wave mod. This controller was 23 bucks delivered, and makes a great starting ingredient for a modified controller.
