Finite Element Analyses of a TLA-type Synchronus Reluctance Machine

Abstract

Abstract— Generating energy efficient and eco-friendly electrical machines has been recently focused by researchers due to rapid decline in energy sources and increase in greenhouse gas effect. Since Inductance Machines have some drawbacks: low torque capability, low efficiency hence high energy consumption, and high carbon dioxide emission, designing Synchronous Reluctance Machines is crucial to overcome these drawbacks of Inductance Machines. Synchronous Reluctance Machines have attractive features: higher torque capability, enhanced efficiency, reduced greenhouse gas emission, longer lifetime and maintenance period comparing with Inductance Machines. In this study, flux barrier number, shape of flux barriers and rotor position effects on machine’s performance is carried out by Finite Element Analyses. The analyses has concluded that the hyperbolic shaped machine with four barriers is the optimum design considering performance parameters and rotor position considerably affects torque, saliency ratio, power factor and efficiency of machines.
