szczelina powietrzna - Opis:
- The problem of aucoustic or audible noise, as often referred to, in electric machines is partly magnetic, partly mechanical and partly areodynamic. The so called magnetic noise is the part of acoustic noise that originates from the action of magnetic forses in the magnetic circuit of an electrical machine. Magnetic noise comes into effect when the magnetic field is existed. The analysis influence of the magnetic wedges closing the stator slots on the air-gap flux dencity in the induction motors was conducted by means of a model being a representation of a fragment of the motor's circuit. As a subject of analysis, the area being a cross section in plane transversal to motor's axis and covering stator slot and rotor slot together with neighboring teeth has been adopted. The performed calculations proved that in the model, relative position of slots with respects to each other results in changes of distribution the air-gap flux density. The magnetic wedge closing the stator slot influence on the amplitude and phase value all the air-gap flux density harmonics. In this article there are shown the calculate resultates this dependence.
