Three-Phase Balanced Winding

This course covers the fundamental aspects of AC machines, focusing on the concept of double-layer three-phase balanced winding. It provides a comprehensive understanding of how windings are laid in three-phase machines, the specifications of the total number of slots, number of poles, and the electrical angle between two consecutive slots. The course also explains the concept of short-corded coils and how to create a winding which is short pitched by one slot. It further delves into the 60-degree phase spread winding and the 120-degree phase spread winding, explaining how the windings are distributed in each case. The course concludes with a discussion on the distribution factor and how it varies depending on the phase spread winding. Additionally, the course covers the production of a rotating magnetic field in an AC machine, the concept of resultant field in electrical phases, and the impact of time-varying current on the rotating magnetic field.
