The "Principles of Electrical Machines" begins by explaining the fundamental laws of electromagnetism:
: A highly respected author in the fields of engineering and physics, Mr. Mehta has been publishing educational books for over three decades. He has also written other popular textbooks, including Basic Electrical Engineering , Principles of Electronics , and Principles of Power Systems .
DC motors utilize the Lorentz Force Law to produce mechanical rotation when current flows through a magnetic field. 2. Transformers (Single-Phase and Three-Phase)
Based on the force experienced by a current-carrying conductor in a magnetic field. Mehta and Rohit Mehta through several online repositories
: Open-circuit and short-circuit tests determine core losses and copper losses. 3. Synchronous Machines
The operation of electrical machines is based on the principles of electromagnetic induction and torque production. Electromagnetic induction is the process by which a changing magnetic field induces an electromotive force (EMF) in a conductor. Torque production is the process by which a current-carrying conductor experiences a force in a magnetic field.
Multiple-choice questions at the end of chapters make it excellent for competitive exam preparation (like GATE or state engineering exams). 🔗 Looking for a VK Mehta PDF Link?
