冬季六边形包括一些可见的最亮的恒星，它们在地球北半球的冬季天空中形成了一个大而容易辨认的图案。
The Winter Hexagon involves some of the brightest stars visible, forming a large and easily found pattern in the winter sky of Earth's northern hemisphere.
传统的直接转矩控制采用六边形磁链控制或六区间的圆形磁链控制，造成转矩脉动大，而且当考虑定子电阻压降的影响时，其区间选择存在缺陷。
Traditional DTC uses hexagon flux control or six-section circle-flux. When the voltage of stator resistance is considered, its section choice has defect.
