This part of the training explains analytically why magnetic force harmonics appear at some specific frequencies and wavenumbers depending on topology and slot/pole combination. General formula of magnetic force harmonics in Permanent Magnet Synchronous Machines and Induction Machines are provided by combining permeance, magnetomotive force, and flux density harmonics step by step.
