# Formula for calculating the MMF and its harmonics of n-Phase PMSM with integral slot winding (slot per pole per phase =1 & 2)?

Data\Prerequisites:
Integral slot winding full pitch winding
Slot per pole per phase = 1 and 2 (two different possibilities)
Number of phases : n = 3,4,5,6,7

Assume number of turns = N and current to be pure sinusoidal

1. Is there a general formula (i.e. formula applicable for n-phase machine\windings)?
2. If not, can anyone please provide me a specific formula?
3. Or provide me with relevant literature.

My target is to calculate the harmonics of winding factor and MMF generated due to integral slot windings with more than 3-phases.

• Do you know the number of turns and the current? – Andy aka Apr 1 '20 at 13:47
• hey @Andyaka , thanks for asking, I dont know , current , but assumptions is a pure sinusoidal current . I am lookin for a general formula. Thanks – patelp2205 Apr 1 '20 at 13:52
• MMF = current x number of turns – Andy aka Apr 1 '20 at 14:14
