Abstract
Determination of the parameters of semiconductor thermistors of the starting system of electric motors
Incoming article date: 30.08.2022The article provides a brief analysis of the processes that occur when starting an electric motor. Mathematical relations modeling the process of starting a direct current motor are presented. Graphical dependences allowing to determine parameters of a thermistor providing an optimum start-up of a direct current machine have been obtained.
