PDFAbstract: The article examines the frequency start of an air compressor driven by a 3-phase induction motor. The frequency and voltage values are selected at which the motor’s locked-rotor (startup) torque is close to the breakdown torque. Computer simulation of electromechanical processes is performed when induction motor powered by an autonomous voltage source inverter to estimate the inrush current.
Keywords: Induction motor, frequency start-up, auxiliary converter of electric locomotive, pulse-width control of voltage, load torque, locked-rotor torque, inrush current
