Determinarea dimensiunilor geometrice ale magneţilor permanenţi utilizaţi în excitaţia maşinilor electrice

Abstract

The analytical dependence connecting parameters of a magnetic circuit of the electrical machine with sizes of permanent magnets is obtained. The influence of parameters of a magnetic circuit and sizes of permanent magnets on magnitude of a magnetic induction in an air gap is shown. The technique permitting to define rational sizes of permanent magnets at the stage of precomputations is offered.
