Concentrated winding electric motor having optimized winding cooling and slot fill

摘要: Optimized winding cooling and slot fill of a concentrated electric motor provides means to maximize motor's without decreasing its factor, thereby improving the torque density efficiency. The uses stator with trapezoidal-shaped teeth separated by rectangular slots. Windings placed around each partially slots, leaving spaces between group windings. Cooling tubes are in these leftover spaces. tubes' geometry allows contact every outer turn adjacent windings, providing efficient thermal conduction Because normally unused portion stator, they do not decrease factor. it run at high current, thus
