Vector optimization of a high-speed drive using two-dimensional numerical field calculation
The vector optimization of a high-speed permanent magnet synchronous machine is described with respect to several objectives. The problem is solved directly without any transformation into scalar sub-problems. The objectives are power output at 6,000/min, power output at 16,000/min and constant terminal voltage between 6,000/min and 16,000/min. Nine design parameters can be varied. The problem is solved by a stochastic search algorithm. The electromagnetic machine design is performed by means of the finite difference field calculation program PROFI as a two-dimensional problem taking into account the non-linear characteristics of iron.
