This course focuses on three phase permanent magnet electrical mchines. In the initial sections, we will explore the fundamental concepts of mathematics and electromagnetism, including dot products, cross products, flux, and Maxwell's equations such as Faraday's Law and Ampere's Law. These foundational topics will provide a solid basis for understanding the following material.The third section will delve into the materials used in electrical machines, focusing on both soft and hard magnetic materials.In the fourth section, we will develop the fundamental equations for magnetic circuits and compare it with the basic electrical circuit equation.The fifth section will focus on the details of three-phase permanent magnet synchronous machines. We will cover essential topics such as machine basics, rotating magnetic fields, back electromotive force (EMF), and torque equations. Additionally, we will explore various winding arrangements and the significance of pitch and distribution factors in electrical machines.Section six will introduce motor control techniques, with a particular emphasis on the Clark and Park transformations. We will also demonstrate how to prove the torque equation in the α-β and DQ reference frames.Finally, in the seventh section, we will examine the different losses that can occur in electrical machines and discuss common practices to reduce these losses.
