| Abstract |
Induction motors with low efficiency and power factor are often used in industrial systems. Therefore, increasing the efficiency and power factor can enable the sufficient electrical power for demanding applications such as electric vehicles. In this paper, an induction motor assisted by permanent magnets is proposed to achieve high efficiency and power factor. In addition, its operating principles, torque components, and basic characteristics are analyzed. Simulation results indicate that the torque due to induction is affected by both the flux of the permanent magnets and the slip for a synchronous speed. The proposed motor improves the torque by 14\%, the efficiency by 1.1\%, and the power factor by 0.07 at a slip of 0.1 compared with a conventional induction motor. |
