| Research Abstract |
Small and fractional horsepower single-phase motors are widely used in all aspects of domestic, utility, and special-purpose commercial markets. In this study, a successful rotor design with high efficiency and high starting performance of the line-start single-phase PM motor has been developed. The rotor configuration with the excellent start-up and synchronization capability has been obtained from the simulation results using the finite element method. The rotor was designed, built and used for measuring the starting characteristics. The efficiency of the proposed motor was 80.0% at 113W. It has been found from the experimental results that the proposed motor has the excellent start-up and synchronization capabilities under full-load torque.
