I have started work on my Bridgeport mill. I jury rigged a Sanyo P5 1kW motor with a Rutex amp to get an idea about if it will work. I can get it to move, but at times during the motion it pulses at about four times a second, or stalls with a jerk at the pulse timing. Sometimes it will even reverse direction for a while. I have a fair amount of noise on the encoder lines that seem to be from the motor R, S, T lines. I am now working at solving the noise problems by checking grounds, shielding and ferrite beading, but I got to thinking about the hall encoder and motor lines. Will the motor function at all if I wire the Halls out of sync with the motor lines? My guess is, not even close, but if so, is there a way to figure out how to correct it? Another symptom is, at idle I get a smooth increasing torque when I manually deflect the motor shaft in one direction, and a weaker torque and pulsing by deflecting the motor shaft in the other. As always, I am grateful for any advise.
