Sweet > Did your motor and drive start off life together? No , I totally lucked into this motor from my favorite surplus outlet at $200 to my door. I have swapped spindle motors 4 times in 2 years searching for more power at liw speed. I figure at 6 hp , and 37.5 nm it ought to do well. First I bought the wrong drive , then I bought the amt 31 encoder, harness And programming cable only to find out that I did not need bidirectional u,v,w signal for that drive. I bought 2 wsdi bpu s3 32 30 drives 3 months ago for almost nothing. I have verified these will function with sinusoidal commutatation by using 2 legs of an old synchronous motor I had , I was also able to spin it with the communication encoder , although I never got it stable , and I again believe bilateral outpur us the issue. As I'm swinging an 8 inch facemill the added torque of sinusoidal drive is very appealing. Of note on the wsdi drive , I would have started with trying to get these functional but it took me 3 months to get documentation .
