A2286 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. Figure 1 Figure 2 Dual Voltage Shunt Field Single Voltage Shunt Field Shunt Field Space Heater Arm Interpoles H1 H2 F1 A1 P1 Arm Interpoles Series Field P2 A2 S2 F2 S1 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). Single Voltage Field F1 to + Field supply F2 to - Field supply H1 H2 F1 F2 A1 P1 - S2 F3 F4 S1 Schematic High Voltage Connection F1 to + Field supply F4 to - Field supply F2 & F3 Joined Low Voltage Connection F2 Series Field P2 A2 Dual Voltage Field F4 + Schematic + F1 1/2 Shunt Field 1/2 Shunt Field Space Heater F1 & F3 to + Field supply F2 & F4 to - field supply F1 F3 F2 F4 - F4 F1 F3 F2 + - 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.

To reverse the direction of motor rotation always reverse the armature connections, not the field connections. Connection Drawing: A2286 Connection Plate: ------Connection Decal: --------
