Abstract: This paper presents the study of a high performance 3-Phase 3.7kW 2-Pole line start permanent magnet synchronous motor for pumping system. A method was proposed to study the starting torque characteristics considering line start with high inertia load. A direct-quadrate model including cage was built to study the synchronization capability. Two-dimensional transient finite element analysis was utilized for accurate calculation of efficiency, starting current speed curve and etc. Structural analysis was also conducted to study the equivalent stress displacement of rotor at rated speed.

Keywords: Line start permanent magnet synchronous motor, cage torque, braking torque, structural analysis, efficiency
