Analytical Solution of the Magnetic Field in Permanent-Magnet Motors Taking Into Account Slotting Effect: No-Load Vector Potential and Flux Density Calculation (2009, background): “Moreover, unlike previous models [22]–[27] and [32]–[34], this model includes both radial and parallel magnetization.”
Analytical calculation of magnetic field distribution in the slotted air gap of a surface permanent-magnet motor using complex relative air-gap permeance (2006, methodology): “This general approach to modeling the effect of slotting, used in several other papers as well [4]–[8], is based on multiplying the field distribution in the slotless air gap with the relative permeance function expressed as an infinite Fourier series.”
Analytical Solution for Cogging Torque in Surface Permanent-Magnet Motors Using Conformal Mapping (2008, background): “One approach is to calculate the torque as a derivative of co-energy inside the air gap [1]–[7].”
Analytical Methods for Minimizing Cogging Torque in Permanent-Magnet Machines (2009, methodology): “Based on this analytical technique, tooth pairing and notching techniques based on the simple air gap permeance function were proposed in [5] and [11], while slot pairing and optimization of pole-arc to pole-pitch ratio were proposed in [9] and [10].”
