Effect of the supply voltage asymmetry on the service life of a linear induction motor
The article assesses the effect of power supply voltage asymmetry on the service life of a flat linear induction motor in the millstone mill drive. To achieve this goal, the thermal scheme for replacing this engine was chosen, a mathematical model of thermal processes in the engine and a computer program in the object-oriented modeling Matlab (Simulink) were developed. The resulted from the supply voltage asymmetry temperature rise of the inductor winding of a linear induction motor was determined with the computer program. On the basis of the Montzinger equation, graphs of the dependence of the relative service life of a linear induction motor on the coefficient of the reverse sequence were determined and plotted.
