In this video Prof. Miller explains the close relationship between the circuit theory, the control theory, and the field theory of electric machines. After a brief review of the nature of performance calculations, we see how the concept of the space-vector unifies the physical principles and the control methods for DC and AC machines, and goes beyond the scope of classical teaching to include the power-electronic switching inverter. The space-vector concept is explained in detail alongside Park’s transform, which is used to deal with saturation in the important IPM motor, using the finite-element method in an extremely efficient way. The conclusion is that a set of modern software tools redefines (and greatly extends) the classical concept of the unified theory of electric machines.
