In this paper, we first show the differences in frequency response between formula-based inductance extraction and frequency dependent inductance extraction to demonstrate the need to capture high frequency effect. Then a novel frequency dependent reluctance extraction method is proposed by using a robust...
Here—p is the number of pole pairs, Ld and Lq are d-q axes inductances respectively and id and iq are d-q axes currents flowing in the stator windings. As can be seen in Eq. (1) the main electromagnetic variables are the d-q axes inductances. As it was discussed previously, d-...
Applying the co-energy formula to equations for torque, Tph=∂W(θph)∂θr, and energy, W(iph,θph)=iph∫0λph(iph,θph)diph yields an integral equation that defines the instantaneous torque per phase, that is, Tph (iph,θph)=iph∫0∂λph(iph,θph)∂θphdiph. Integrating...
