Method for analyzing starting performance of cage type motor

The invention discloses a cage type motor starting performance analysis method, which relates to the field of starting performance calculation, and comprises the following steps: S1, carrying out electromagnetic field finite element modeling and calculation, and establishing a database; s2, carrying out electromagnetic analysis iterative calculation in the starting process; s3, carrying out starting process transient heat transfer calculation; s4, carrying out mechanical calculation in the starting process; s5, performing judgment, if the angular acceleration is calculated and judged to be small enough, ending the calculation if the angular acceleration is small enough, and if the angular acceleration is small enough, performing two-dimensional interpolation from an electromagnetic torque calculation result database by taking the temperature of the next time step obtained in the S3 and the speed of the next time step obtained in the S4 as input, and outputting a result; s7, the steps S3-S6 are repeated until
