Unknown Motor Wiring
If you are uncertain which is the A pair and which is the B pair, you can use an
ohm meter and the following chart to determine the pairs (and the center taps on a
6- wire motor)
A to A~
About 1-10 ohms (Equal to B to B~)
B to B~
About 1-10 ohms (Equal to A to A~)
A or A~ to B or B~
No Continuity
A Center to A or A~
½ the resistance of A to A~
B Center to B or B~
½ the resistance of B to B~
B Center to A or A~
No Continuity
A Center to B or B~
No Continuity
If the A and A~ or the B and B~ are reversed, the motor will spin the opposite
direction. This can easily be corrected by changing the motor polarity in the
Setup…Motor Settings menu in the FlashCut CNC software.
