Coil Distribution in Electrical Machines

This course covers the comprehensive understanding of coil distribution in electrical machines. It begins with the concept of coil distribution and how it is used to effectively utilize the surface of the machines. The course further explains the displacement of coils by an angle, the resultant voltage, and the concept of electrical and mechanical angles. It introduces the idea of multipolar machines and their representation as two-pole machines. The course also discusses the distribution factor, which is the ratio of the resultant voltage when the coils are distributed to when they are concentrated. It then moves on to the concept of elliptical machines and coil distribution, the angle between two consecutive slots, and the number of coils distributed. The course also introduces the concept of pitch factor and explains how to calculate the RMS voltage induced in coils. It concludes with a detailed explanation of three-phase double layer winding, its calculation, and distribution.
