A 4-wire motor is the same as a 6-wire motor except that the center
taps (CT) are not brought out. To use a 6-wire motor in a 4-wire
configuration you can isolate the center taps for a series (full coil)
configuration. Series configurations produce the most torque per
amp but have the disadvantage of poorer high-speed performance.
