Abstract Locked-rotor current is an important factor which indicates the starting performance of a motor, however, a phenomenon is discovered during lots of tests on the line-starting permanent magnet synchronous motor (PMSM). The amplitudes of three-phase locked-rotor current is different distinctly, and change with the position of the locked rotor. In order to find out the essential reason of this phenomenon, a 55kW PMSM is taken for example and time-stepping finite element method (T-S FEM) is utilized for calculating the locked-rotor starting in different cases. The effect of asymmetric rotor magnetic circuit and saturation caused by the permanent magnet on the locked-rotor current is analyzed through researching flux density changes and distribution. And the main reason for the different amplitude of three-phase locked-rotor current is revealed. The saturation caused by the permanent magnet can play the unbalanced role on the magnetic circuit, which is locked-rotor saturation effect. Referring to the measured data and comparing current calculation results with different rotor locations and types of parameter magnet. The availability of the conclusion is verified.

Key words： PMSM T-S FEM saturation effect locked-rotor current
