Abstract
The article discusses the performance characteristics of machines with a common criterion for all characteristics – the same work per cycle. The conclusion of analytical dependences characterising the movement of the electric drive in the transient mode is given, that is, taking into account the influence of var- ious quantities included in the equation of motion on the magnitude of the moment of inertia of the flywheel masses, with different types of load and different coefficients of unevenness of rotation. The zones of influence of the slope steepness of the mechanical characteristic MD(ω) on the required value of the moment of inertia are determined. It is shown that the values of the moment of inertia for aggregates with a smooth load are less than for aggregates with a sharply varying load, and that taking into account the influence of the dependence of MD(ω) on the required value of the moment of inertia J at large values of the coefficient of unevenness of motion δ is more necessary than at small values δ.
