Abstract
Inventia se refera la o executie a circuitului magnetic al motorului de curent continuu cu comutatie electronica, în special la masini de putere mica, cu un rotor cu magneti permanenti cu cel putin trei bobine sau grupe de bobine în stator. Scopul inventiei este ca, la motoarele cu comutatie electronica cu cel mai mic numar posibil de bobinaje ale statorului sa se obtina un cuplu de rotatie cât mai constant pe întregul unghi de rotatie al rotorului (de 360 degree ) cu randament optim si o utilizare favorabila a magnetilor si sa se realizeze concomitent o ondulare foarte mica a semiundei redrsate a tensiunii electromotoare a bobinajului.The invention relates to an embodiment of the magnetic circuit of the DC motor with electronic switching, especially for low power machines, with a permanent magnet rotor with at least three coils or stator coil groups. The aim of the invention is that, in the electronic switching motors with the smallest possible number of stator coils, a torque can be achieved as constantly as possible over the entire rotation angle of the rotor (360 degrees) with optimum yield and favorable use of magnets and to achieve a very small curl of the redundant semiconductor of the electromotive voltage of the winding.
