Analytical and numerical computation of air-gap magnetic fields in brushless motors with surface permanent magnets [PDF]
This paper extends the theory of the air-gap magnetic field in permanent-magnet (PM) brushless motors. Scalar and vector potential solutions to the field equations are brought together to unify many of the important practical methods already in use.
