CALCULATION FEATURES ASYNCHRONOUS MACHINES WITH FERROMAGNETIC ROTOR
Abstract
Improving the reliability, efficiency and energy (fuel) efficiency is currently the most important problem of improving autonomous electric power systems in the marine energy sector. Purpose of the article - the ability to improve the performance of the machine by selecting a ferromagnetic material of the rotor with certain parameters, including the one for the current density in the rotor. At the same time, the choice of parameters of the machine will be carried out with a view to ensuring the limiting rotational speeds of the rotor. The proposed method improves the accuracy of calculation of asynchronous machines, reduce the amount of computation to identify all existing analytical relations unknown parameters. In the calculation of asynchronous machines with a massive rotor and the coating applied to it this method allows to determine the optimal parameters of the coating material to obtain the desired characteristics of the machine.
