The Torque Tensor or the General Machine

Abstract

The general machine described in this paper, and also in a previous one by the author,1 includes all conventional electric machines and models of analysis as special cases. In this paper, the typical elements of the inductance matrix and torque tensor are derived. From these, the impedance matrix and torque tensor of any electric machine can be readily found. Examples of application are shown. No Christoffel transformations are necessary. The paper provides unified and systematic ways of analyzing electric machines.
