The Design and Optimization of Synchronous Reluctance Motor Drive System for Low-Speed Direct-Drive Mining Applications
The Synchronous reluctance machine is very attractive due to its robustness, absence of magnet, easiness to control, simplicity and passive rotor structure. This paper deals with the design and optimization of synchronous reluctance motor for mining applications at low-speed with direct-drive. Therefore, it is intended to detect the stator and rotor parameters which provide a high efficiency (91.13%) and a good average torque (959Nm). In this regard, two different rotor geometries with multiple width size of flux barriers and flux carriers have been considered in this work and their effects are proposed through finite element analysis. A suitable geometry of the rotor is proposed for further investigation and the development of prototype design.
