The number of coils per phase is equal to ________

The correct answer is option 1):(Total number of coils / number of phases)

Concept:

• Total number of coils per phase = (Total number of coils / Number of phases)
• If the number of slots/pole/phase is an integer, the winding is called integer-slot winding. If the number of slots/pole/phase is fractional and superior to 1, the winding is called fractional-slot winding.
• If the number of slots/pole/phase is fractional and inferior to 1, the winding is called concentrated winding. Windings with the same number of slots/pole/phase have the same winding factor.
• Their winding layouts consist of the same basic sequence repeated by the number of winding symmetries (or machine periodicity).
