Analytical formula for rotating motor permanent magnet MMF in a general case
This paper presents an analytical formula for the permanent magnet (PM) magnetomotive force (MMF) in a slotted PM rotating motor. To derive this formula, an analytical 2D solution of Poisson's equation for the equivalent slotless configuration using the Fourier series is applied. The formula comprises the case when the PM poles are not symmetrical. The obtained PM MMF can be used to determine the magnetic field using the slot modulation
