【摘要】 就直接转矩控制中运用折角的方法得到的十八边形磁链轨迹的谐波含量进行了分析，提出了在原六边形磁链轨迹基础上实现折角十八边形磁链轨迹的方法，并可顺利地实现了二者之间的切换，同时指出了其不足之处．更多还原

【Abstract】 Analyzes the harmonic components of eighteen-corner stator flux curve. The curve comes from fold angle Direct Self-Control. A realization is given for the eighteen-corner stator flux curve based on the six-corner stator flux curve. The eighteen-corner stator flux curve can switch to the six-corner stator flux curve. In the meantime, the shortcomings are pointed out.更多还原
