If this motor is installed as part of a motor control drive system connect and protect the motor according to the control manufacturers diagrams. A series wound dc motor like in the case of shunt wound dc motor or compound wound dc motor falls under the category of self excited dc motors and it gets its name from the fact that the field winding in this case is connected internally in series to the armature.

When diagnosing a faulty automotive motor it is often impossible not to perform major disassembly such as the fuel pump itself. If a single phase motor is single voltage or if either winding is intended for only one voltage the terminal marking shall be determined as follows. Use figure 1 if your motor has a single voltage shunt field.

Failure to use the double wrench technique could cause undue strain to be placed on the internal connections and could also result in cracked seals around the bus bars. Motor connections your motor will be internally connected according to one of the diagrams shown below. Motor wiring diagram dc.
