Peter Vas, at the time of the book’s publication, was a Professor of Electrical Engineering at the University of Aberdeen. His academic credentials and research focus on electrical machines and drives positioned him as an ideal author for a monograph of this depth. The book draws heavily on his research and teaching experience, offering a perspective that bridges theoretical rigor with practical engineering concerns.
While mathematically dense, the book balances theory with practical design challenges. This balance makes it a highly cited and enduring reference in the field of electrical and electronic engineering.
The monograph is aimed at multiple audiences within the electrical engineering community. For , the book provides a structured path to understanding advanced machine theory, beginning with foundational concepts and progressing to sophisticated applications. The careful development of space-vector theory from first principles makes it accessible to graduate students and advanced undergraduates.

The book meticulously defines the transformation from three-phase variables (a,b,c) to a single complex vector. For currents, this is typically: ( \veci_s = \frac23(i_a + a i_b + a^2 i_c) ), where ( a = e^j2\pi/3 ). This is not just a mathematical trick; it physically represents the rotating field.

: While technically rigorous, it is designed to be self-contained; readers do not need prior knowledge of space-vector theory to begin. Impact on the Field While mathematically dense, the book balances theory with
. This vector approach allows researchers to analyze machine behavior based on the magnitude and orientation of the magnetic field rather than just time-varying waveforms. Complex Plane Representation

The Park transformation can be represented as: $$ \beginbmatrix v_d \ v_q \endbmatrix = \beginbmatrix \cos(\theta) & \sin(\theta) \ -\sin(\theta) & \cos(\theta) \endbmatrix \beginbmatrix v_a \ v_b \endbmatrix $$ where $\theta$ is the angle between the dq-axes and the abc-axes.
Monographs in Electrical and Electronic Engineering are essential reading for researchers and graduate-level students. This specific volume on space vector theory is favored for:
