Implementação de um algoritmo para o cálculo do fator de preenchimento de ranhuras em máquinas elétricas síncronas de imã permanente

Abstract

The optimization of an electrical machine project that seeks to improve the efficiency on the electrical to mechanical energy conversion should be focused mainly on the mitigation of the impact caused by the main sources of losses on this devices, such as the Joule losses at the winding, the eddy currents at the magnetic core, mechanical losses caused by friction and ventilation, and other additional losses. The slot filling factor is one of the limiting parameters on this optimization. This work was developed with the intent of implementing an algorithm that does the calculation of the maximum possible slot filling factor for a determined machine, through the ideal positioning of the wires inside the stator slots, and as consequence, achieving a decrease in the temperature rise, also increasing the torque density per volume.
