Terminal Markings and Connections For NEMA DC Motors

All connections are for counterclockwise rotation facing the end opposite the drive. For clockwise rotation, interchange A1 and A2.
Some manufacturers connect the interpole winding on the A2 side of the armature.
When the shunt field is separately excited, the same polarities must be observed for a given rotation.
