The increase in the energy consumption of lifting and transport machines in transient operating mode requires the creation of mathematical models and, on their basis, the development of recommendations for increasing economy. Important reasons for reducing the economy of lifting machines are changes in speed and load, deviations from the optimal value and causes an increase in energy dissipation. Another reason for the increase in lost energy is the process of machines with a loss of kinetic energy during their shutting-off. Increasing the economic showings of machines is possible by reducing its nominal power, which leads to a deterioration in dynamic qualities. A promising method of increasing the economy of machines is using of braking energy recovery, its accumulation and using during further acceleration. In this case, the increase of efficiency occurs without reducing the dynamic qualities and showings of the machine.

The prospects of using of flywheel energy accumulators in the lifting and transport industry
