This article describes a novel measuring inductance strategy on direct current (DC) machines. Measuring self-inductance and mutual-inductance in rotating machines is always a very challenging task over a few decades. A significant challenge in modeling electric machines is to obtain their variables and parameters as accurate as possible. The method developed in this paper using a DC source for measuring the inductance in a DC machine overcomes some problems associated with traditional methods by using an alternating current source. In particular, it enables the field winding to carry its rated DC. This approach has demonstrated the feasibility of taking measurements for inductance in a DC machine and providing its field current that is sufficient to lead magnetic saturation, such that the flux can be kept the same as the supplied flux to the running DC machine. The proposed method for measuring both self-inductance and mutual inductance of the DC machine armature winding coils has played a main role in modeling DC machines under a wide range of operating conditions.
