Lecture

Synchronous Motor: Structure

Description

This lecture focuses on the structure of synchronous motors, emphasizing the need for a polyphase winding to create a rotating field. Various winding construction possibilities are explored, with a focus on small motors. The evolution of permanent magnet synchronous motors, driven by the need for high-speed data storage in computer hard drives, is discussed. Different rotor designs, including full disk, tile-shaped magnets, and tangential magnetization, are presented. The integration of electronics for motor control and the optimization of winding configurations for efficiency are also covered, showcasing examples of concentric windings and compact motor designs.
