Magnetic Field Analysis of Multi‐Segment Modulated Pole Motors Based on the Air Gap Domain Multi‐Harmonic Method

open access: yesIET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
A subdomain analytical model for multi‐harmonic air‐gap subdomains is proposed to predict motor magnetic fields containing complex harmonic components. Theoretical analysis demonstrates that this model effectively reduces the matrix dimension during analytical computation, resulting in lower computational time costs for the same harmonic order while ...
