Investigation of the Mechanical and Electromechanical Starting Characteristics of an Asynchronous Electric Drive of a Two-Piston Marine Compressor

In the article, mechanical and electromechanical starting characteristics of an asynchronous electric drive a two-piston ship compressor are investigated by numerical method. A distinctive feature operation reciprocating is that its load torque changes with certain frequency. The dependence on shaft piston angle rotation presented in form Fourier series. Moments inertia reduced to single system performs rotary motion. Mechanical constructed. estimation degree pulsations made. It determined has large amplitude ripple shaft, which, turn, affects magnitude current drive.
