带嵌入式磁体及梯形走向电磁力的永磁激励无刷同步电机
摘要：
本发明涉及一种带有一个定子和一个转子的永磁激励无刷同步电机。转子可旋转运动地支承在定子内。转子具有多个其中嵌入永磁体的空隙。在定子和转子之间设置了气隙。如此构造转子的朝向定子的外轮廓，使得在单齿定子绕组中因感应而引起的电磁力呈梯形走向。在30°到90°之间的电角度范围内连续存在电磁力的最大值。
摘要（英）：

A brushless synchronous machine is energized by permanent magnets with a stator and a rotor. The rotor is supported within the stator to allow rotation. The rotor has a plurality of cutouts into which permanent magnets are embedded. An air gap is provided between the stator and the rotor. The outer contour of the rotors is formed such that the electromagnetic force induced by the individual stator tooth winding has a trapezoidal characteristic. The maximum value of the electromagnetic force is present uninterrupted in an electrical angle range of 30 DEG to 90 DEG .
