In view of the calculation of starting characteristics of small asynchronous motor in different starting modes,the two-dimensional electromagnetic model is constructed based on the finite element method to simulate the starting characteristics of the motor. Considering the effect of the motor end on the overall electromagnetic simulation in the two-dimensional model, the parameterization of the resistance and leakage inductance of the stator and rotor end are equivalently processed to the model by the method of field circuit combination. The power models of direct starting, Y-△ step-down starting and constant frequency voltage ratio starting are established by MagNet and Simulink software according to the starting circuit structure. The starting time, starting current and starting speed of the motor under different starting modes are compared and analyzed. The results show that the model can accurately simulate the characteristics of asynchronous motors under common starting methods.

Key words: asynchronous motor, starting characteristics, finite element method, end treatment, direct starting, Y-△ step-down starting, constant frequency voltage ratio starting, two dimensional
