The effect of various types of cooling the heating process. For temperature measurements were considered a different performance of the fan, and the inclusion of the rod on heating at different times, which allows to take into account the actual operating conditions and engine cooling systems. On the basis of experimental data and compile regression model the processes of heating rod and shroud. For each model, the coefficients are calculated by least squares approximation. Using the method of recursive equations to obtain a comprehensive two-parameter model of the heating process. The proposed method of automatic adjustment to the law of cooling control based on the initial values of the stator current. Defined standard processes of change of current described as a regression polynomial models of the 3rd degree. Selecting the appropriate model is carried out microprocessor. Microprocessor system performs the measurement and calculation of currents, the choice of the control law and control the drive at startup synchronous motor.
