Abstract

Inventia se refera la o masina electrica de curent continuu cu rotor cilindric, bipolar, cu magneti de ferita si concentratori de flux, la care forma specifica a pieselor polare feromagnetice care realizeaza concentrarea fluixului magnetic al magnetilor permanenti plasati atît pe directia axei polilor cît si pe directia axei neutre, precum si a jugurilor exterioare de închidere a cîmpului, fac ca sa se obtina un diametru rotoric realtiv mic, deci si un moment de inertie relativ mic si asigura fixarea magnetilor permanenti nefiind nevoie de lipire.The invention relates to an electric DC motor with a cylindrical, bipolar rotor with ferrite magnets and flux concentrators, to which the specific shape of the ferromagnetic pole parts which realize the concentration of the magnetic fluff of the permanent magnets placed both in the direction of the pole axis and on the direction of the neutral axis as well as the outer field closures make a small real-world rotor diameter, and therefore a relatively small moment of inertia, and ensure the permanent magnets are not fixed.
