The thought of the coming expedition to the South Pole keyed them up to a high pitch of excitement. 一想到即将去南极考察,他们都感到极度兴奋。
A Method of Change-Pole for Full-Pitch Winding Based on Ampere-Conductor-Unit 安导元整距变极法
Performance test and application of electrostatic precipitator of superhigh tension and wide pole pitch 超高压宽极距电收尘器的性能试验与应用
These analytical results show that the change of the slot width and pole pitch affect the performance of the motors greatly. It also demonstrates that skewing poles could efficiently decrease the torque ripple of PM motors. 分析结果表明,定子槽宽和极宽的变化会对电机性能产生较大影响,永磁电机采用斜极结构,可有效减小电磁转矩波动。
The structure of similar pole and slot number can increase the winding pitch coefficient, and reduce cogging torque ripple effectively with the reasonable combination of pole number and slot number. 极槽数相近结构不仅可以提高绕组短距系数,而且极数和槽数的合理配比能够有效地削弱齿槽转矩。
