Abstract :
Inductance characteristics, torque variations and ripple according to current and position of multi-layer buried magnet synchronous machine with field-weakening operation are presented. The rotor structure optimal design of buried magnet synchronous machine with high performance is investigated and optimization result and comparison among design candidates is shown. For the fast and accurate search of multiple optima, auto-tuning niching genetic algorithm is used and final solution is selected considering various design factor.
