Abstract
The structure and study of the starting characteristics of the electric drive of piston ship compressor refrigeration plant using a mathematical model of unbalanced load moment are made in the article. The dependence of the shaft load of the electric drive of a piston compressor on the angle of rotation is presented in the form of a mathematical model. It was determined that by adding a variable moment of inertia of a flywheel to the model, creating a moment of inertia, the pulsation of rotational speed and current at the steady state decrease, and the start time also becomes less, which favorably affects the operation of the device. The possibility of installing a flywheel of variable moment of inertia on the electric drive shaft of a reciprocating compressor are studied. Also, the feasibility of this installation is shown.
