Rotating Field and Winding: Introduction

This lecture introduces the concepts of rotating fields and winding, focusing on how winding is done, defining key terms like phases, poles, and coils, and showing examples with asynchronous and synchronous motors. The instructor explains the importance of winding arrangements in creating the desired magnetic field for motor operation, illustrating the differences between distributed and concentrated windings. The lecture covers the basics of poles and phases in electromechanical conversion, demonstrating how different winding configurations impact the magnetic field distribution in the motor's air gap. By the end, students will understand how winding arrangements influence the motor's magnetic field and how to connect the phases for proper operation.
