Sensitivity Analysis and Design Optimization of Synchronous Reluctance and Permanent Magnet Motors

Abstract

Synchronous Reluctance and Permanent Magnet Motors have emerged as an exclusive and important technology for various industrial applications in many aspects compared to conventional motor drives owing to its improved torque density and efficiency. Since the electromagnetic design of Synchronous Reluctance and Permanent Magnet Motor is complicated involving several geometrical parameters, numerous techniques have been proposed for identifying the sensitivity of each geometrical parameter toward performance objectives and various optimization algorithms have been utilized in obtaining designs meeting out application-specific requirements. This paper provides an indubitable review of the technology status and trends in such sensitivity analysis tools and optimization algorithms for Synchronous Reluctance Motor and Permanent Magnet Motor design. Also, this paper compares two sensitivity analysis tools in the electromagnetic design of Permanent Magnet-Assisted Synchronous Reluctance motor as a case study, indicating its effectiveness in arriving at design-specific criteria establishment.
