I just finished up a retrofit of a small spectralight turning center. I installed keling 284 oz in motors, and 4XCNC10B to drive them. I tried it out and all I get is stalled motors. I also got to thinking how does the driver know which field to engergize. I just wired it up. I did test the 8 wires coming from the motor to find out which ones went together but does it need to pulse the field in order? How do I know which wire goes where.
