ROTOR DESIGN AND OPTIMIZATION OF SYNCHRONOUS RELUCTANCE MACHINE

Abstract

The world has a bottomless appetite for electricity. Much of this electricity is used to power electric motors. Thanks to that electric motors represent a huge potential for energy savings. Synchronous reluctance machines are promising electric machines for energy savings. Key to success of synchronous reluctance machines is laying in elimination of rotor losses. This article deals with the design of synchronous reluctance machine of the transverse-laminated type. Rotor design has been made for two different rotor geometries based on general design recommendations. These geometries are studied and compared by using 2D finite element analysis. The geometries are developed by optimization algorithms after that. Optimized design is used for fabrication of synchronous reluctance machine. On fabricated synchronous reluctance machine several measurement and analysis of performance has been made. Finally fabricated synchronous reluctance machine is compared with induction machine with the same frame size.
