All MTS Automation two-inch motors are 4-pole. The three-inch, four-inch, six-inch, and
eight-inch motors are 6-pole motors.
For brush motor operation, no resolver alignment is required and the R lead connects to
armature (+) and the T lead connects to armature (-). These connections will cause
clockwise rotation from the shaft end of the motor.
