Study on synchronous induction hybrid motors

Today, various interior permanent magnet synchronous motors (IPMSMs) are developed. Especially, in the capacity of 3.7 kW or less, interior permanent magnet synchronous induction motors (IPMSIM) have been interested. IPMSIM with a squirrel cage rotor has line start capability and higher efficiency than conventional induction motor. In this paper, we propose a novel hybrid motor that operates simultaneously as a synchronous motor and an induction motor, and present the characteristics as a hybrid motor obtained by 3D finite element analysis.
