✅ Covers everything from smooth-air-gap to salient-pole machines.
The book opens with a thorough introduction to the space-vector method, beginning from first principles and building progressively toward advanced applications. Chapter 2, “The Space-Vector Method,” establishes the necessary mathematical foundation, covering topics such as:
Using space vector theory, FOC decodes the stator current vector into two orthogonal components in the synchronous reference frame: Transient & Steady-State A drive system is only
: The book demonstrates how traditional models (like the matrix model) can be derived directly from the simple space-vector model without complex matrix transformations. Transient & Steady-State
A drive system is only as good as its power electronics. The monograph devotes significant focus to , which has largely superseded traditional Sinusoidal PWM (SPWM) in high-performance applications. This means it has three separate electrical currents
An electric motor uses three-phase power. This means it has three separate electrical currents pushing power at different times. Tracking all three phases at once is very difficult.
The monograph provides a rigorous derivation of the voltage limit ellipse and current limit circle. For drive engineers, the section on is invaluable. Using space vectors, the book explains precisely why torque collapses at high speed (back-EMF approaches DC bus voltage) and how to inject negative direct-axis current (Id) to reduce flux, allowing the machine to spin beyond its base speed.
