Winding Table for 3-phase Distributed Winding with Examples — Lesson 6

This lesson covers the concept of winding in electrical machines, focusing on a 12-slot, 2 pole, three-phase balanced winding. The lesson explains how to distribute the coils, calculate the distribution factor, and understand the pitch factor. It also discusses the importance of coil span and the role of slots per pole. The lesson uses an example of a 24-slot, 4-pole machine to illustrate the process of winding, including the placement of coils and the calculation of the distribution factor. It emphasizes the importance of understanding the number games in winding and the need for careful connection of the group of coils.

Key Takeaways

- Winding in electrical machines involves distributing the coils, calculating the distribution factor, and understanding the pitch factor.
- The coil span and the number of slots per pole play a crucial role in winding.
- In a 24-slot, 4-pole machine, each phase will have 8 coils, and the distribution factor can be calculated using the number of slots per pole per phase.
- It's important to connect the group of coils carefully to avoid phase opposition and zero voltage.
- Understanding the number games in winding is crucial for translating the winding diagram into a physical machine.
