This book serves as an initial resource for the practical course on electrical machines. Typically, practical sessions are conducted with tedious monotony, utilizing components such as dull monotony, place components, hook-up wires, and connect wires, with results expected well beforehand. Regrettably, there is a scarcity of books and manuals that can inspire and guide students during experimentation.

This publication aims to address the existing gap in the field of practical experimentation and instill a constructive attitude towards conducting experiments. The experiments included in this book cover a broad scope of topics that support a complementary theoretical course on electrical machines. The objectives to be accomplished at the end of each experiment are clearly stated at the outset, providing direction and purpose for the students. The question bank is designed to facilitate the analysis of results, the correlation of theoretical knowledge with observations, and the comprehension of practical limitations.
