Field Path Design Assessments of a High-Performance Small-Power Synchronous-Reluctance Motor

Abstract

With the ever rigorous operational efficiency requirements, effective copper loss reduction is one of the viable approaches for smallpower alternative current motors. Among those cost-effective schemes, by eliminating the rotor windings while keeping the same stator structures, the synchronous-reluctance motor (SynRM) offers a potential substitute for those small-power applications that the induction motors are commonly adopted. Since the key factor that affecting the SynRM generated torque will be the difference between its direct-and quadrature-axis inductances, by arranging the rotor field paths aligned to the direct axis and considering the possible cross-coupling magnetic saturations on the rotor ribs and segments, the performance impacts due to field path arrangements on the rotor will be thoroughly evaluated by three-dimensional finite element analyses. From experimental measurements, it is clear that the operational objectives can be achieved and the adequacy of the proposed design guidance can then be confirmed.

Electromagnetic–Mechanical Design of Synchronous Reluctance Rotors With Fine Features

“…The design of the rotors usually encompasses the selection of rotor topology, either the axially laminated variant [1] or transversely laminated variant [2], the latter being the most popular. When designing the transversely laminated variant, the number of flux barriers and their shape (otherwise known as 'guides') [3], the ratio of iron to air in the barrier windows [4], known as the insulation ratio, or the barrier placement [5] is typically investigated.…”
