The motor stator iron core and insulation layer were regarded as a kind of equivalent material by means of the reasonable equivalent principle. Starting from the 1-D transient temperature field model, the variation law of temperature in a periodic pulse-type linear induction motor stator was studied. The main factors that had an effect on the time constant of the stator temperature attenuation were analyzed. The determination method about the node number of the transient thermal network model was put forward with the use of the analytic results of the transient temperature field model. The variation of the stator temperature could be quickly predicted through the transient thermal network model. The effect of the temperature variation on the coil loss was considered, and the correction of the calculation model was verified through the test data. This paper may provide a valid simple method for the analysis and calculation of temperature in the periodic pulse-type linear induction motor stator.
