Motor Wiring Diagram
D.C. Motor Connections
Your motor will be internally connected according to one of the diagrams shown below. These connections are in
accordance with NEMA MG-1 and American Standards Publication 06. 1 - 1956. Use figure 1 if your motor has a single
voltage shunt field. Use figure 2 if your motor has a dual voltage shunt field.

Field Connections
Your motor will be supplied with either a single voltage or a dual
voltage shunt field. Single voltage shunt fields have only two
field leads (F1, F2) while dual voltage shunt fields have four
field leads (F1, F2, F3, F4).

Thermal Sensor Connections
Leads P1 and P2, when supplied, are from a thermal sensor element attached to an interpole coil. This contact is
normally closed, opening on motor overtemperature.
Armature Circuit Connections
Some motors are furnished with a stabilizing series field (S1, S2). Check the drive control diagram to see if the series
field should be connected into the armature circuit. Connect the motor as shown below for clockwise or counterclockwise
rotation.

When A1 and F1 are the same polarity rotation will be counterclockwise when viewed facing the commutator end to the
motor. To reverse the direction of motor rotation always reverse the armature connections, not the field connections.
