An interactive learning approach is taken in this text: theory and calculations are augmented by generic models which are transposed to a simulation platform. The induction machine is by far the most commonly used machine around the globe. We will then extend this analysis to three-phase (three wire) circuits. In the previous chapter, three-phase current control was introduced with the precise aim of being able to manipulate the current space vector. This 'build and play' method visualizes the dynamic operation of a comprehensive set of modules ranging from an inductance to a novel 'ideal rotating transformer' (IRTF). Electric motors are around us everywhere.
