Real Coded Genetic Algorithm for Permanent Magnet Motor Mass Minimization for Electric Vehicle Application

A Comparative Study of Two Permanent Magnet Motors Structures with Interior and Exterior Rotor

“…Figure 1 represents the PMSMER and the PMSMIR with the number of pole pairs is 4 and a number of principal teeth is 6, between two principal teeth, an inserted tooth is added to improve the form of wave and to reduce the leakage flux [Hadj et al, 2007]. The slots are right and open in order to facilitate the insertion of coils and to reduce the production cost.…”

“…It should be noted that the zone of variation of these three parameters varies between 0,2 to 1,6 T [Hadj et al, 2007]. …”

“…where R cu (Tb) is the Resistivity of copper at the temperature of winding T b and L sp is the spire average length defined as follow [Hadj et al, 2007].…”
