Optimum design of axially laminated synchronous reluctance motor, considering centrifugal force and magnetic saturation using FEM and RSM

This paper deals with the characteristics analysis and optimum design of axially laminated anti-rib (ALA) Synchronous Reluctance Motors (SynRM) with consideration to centrifugal force and its effect on the flux path. The rotor core of an ALA type motor is fixed directly to the shaft axis. As the rotor rotates at a speed of 3,000rpm, the rotor receives a centrifugal force of approximately 147.16[kN] per one block (diameter of the outer rotor: 326.6mm). Such a high level of centrifugal force can present potential stress problems on the rotor if it is directly arrached to the shaft axis. In order to resolve these problems, this paper discusses an optimum design for the ALA-type rotor.
