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 ...

Torque Ripple Minimizing of Uniform Slot Machines with Delta Rotor via Subdomain Analysis
Energies, 2021 Since the slot opening is large in the uniform slot machine, the torque ripple generated by overlapping or misaligning with the rotor cavity is remarkably large in the case of interior permanent magnet (IPM) machine. In this work, it is observed that the
