The introduction of —pioneered by Kovacs and Racz, and later popularized through Field Oriented Control (FOC)—provided a mechanism to visualize and manipulate the magnetic field inside an electric machine in real-time. Unlike a phasor, which represents a single sinusoidal quantity, a space vector represents the instantaneous spatial distribution of the magnetomotive force (MMF) in the air gap of the machine.

In a world of simplified knowledge, go exclusive. Go deep. Go vector.

What makes this specific monograph "exclusive" and a staple in university libraries is its depth. Peter Vas provides the "exact" and "simplified" performance analysis of a.c. machines, extending the model to advanced subjects like double-cage induction machines salient-pole synchronous machines

It is designed for students, teachers, and researchers in industry who need a deep, rigorous understanding of machine operation.
