Abstract :
Line start permanent magnet synchronous motor has the potential for energy saving. Different issues regarding rotor of this machine are discussed in this paper. Energy saving potential of the commonly used rotor geometries for this machine is compared with the help of nonlinear model based on phasor diagram. The new rotor geometry, which eliminates the drawbacks of conventionally used rotor geometries, is proposed. It shows highest potential for energy saving without any increase in machine cost
