IET 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 ...

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.The position measurement angle error (contains measurement delay angle and periodic angle error) plays a significant role in PMSM drives, especially when the motor is rotating in the flux weakening (FW) region. In this paper, the impact of the position angle error on the performance of the PMSM drives for EPS in a wide speed range has been elaborated ...
