Winding Table for 3-phase Distributed Winding — Lesson 5

This lesson covers the process of creating a three-phase winding. The lesson begins with the calculation of the number of slots per pole and the separation between consecutive slots. It then moves on to the concept of double layer winding, where each slot contains two coil sides. The lesson further explains the numbering of slots and the creation of a three-phase double layer winding. The instructor also discusses the concept of coil span and the importance of coil side placement. The lesson concludes with a detailed explanation of how to connect the coils in series to ensure all voltages are additive, and how to identify the terminals for each phase.

Key Takeaways

- The number of slots per pole is calculated by dividing the total number of slots by the number of poles.
- In a double layer winding, each slot contains two coil sides which may belong to the same or different phase groups.
- The coil span is always equal to 180 degrees, which means six slots.
- The coils are connected in series to ensure all voltages are additive.
