Self‐start synchronous reluctance motor new rotor designs and its performance characteristics

摘要

Self-start (often called line start) synchronous reluctance motor (a type of synchronous motor) designed with different rotor structures have been analyzed and compared. The torque, output power, rotor mass, and efficiency are calculated through theoretical study. A genetic algorithm is performed to attain optimal machine parameters. The flux distribution, effect on the inductances, starting torque, average torque, power factor, efficiency, and torque ripple are completely examined by the numerical study. The energy consumption comparison of self-start synchronous reluctance motor and induction motor are calculated. Further, a study on the effects of end-ring resistance is discussed for starting and steady-state conditions. Experimental results reveal that the fabricated high efficient rotor structure is closely correlated with the numerical and theoretical studies.
