Abstract: Motor is a nonlinear, multivariate, multi-physics coupling position, Especially with the
plex asynchronous traction motor operating characteristics. In order to better analyze the performance
characteristics of asynchronous traction motor and the motor parameters under different operating characteristics,
the internal field distribution. With this module Ansoft's Maxwell 2D, The establishment of a subway car with a
power of 190kW asynchronous traction motor model, By finite element software, Analysis of asynchronous
traction motors running at different ic flux density of the motor parameters and the characteristic curve,
This is the optimal design of asynchronous traction motors to provide a theoretical basis.

Key words: traction motor; operating performance; characteristic curve; finite element analysis
