Double Layer Full Pitch Winding — Lesson 4

This lesson covers the principles of stator winding design, focusing on full pitch double layer winding. It explains how to select the coil pitch, number of coils, and create a winding diagram using the stubbing and arrow check approach. The lesson uses a 24 slot, 3 phase, 4 pole double layer winding as an example to illustrate the process. It also discusses the Faraday's law of voltage equation, the selection of copper gauge based on current rating, and the verification of magnetic poles using the right hand thumb rule. This lesson also covers the stubbing and arrow check methods for winding connections. The lesson concludes with a detailed explanation of how to make star and delta connections and test the machine under operating conditions.
