摘要
从风机电动机的特点出发,以效率最高为优化目标,建立气隙磁密、转差率、极对数在高效率变极运行时的互相约束关系。以此约束关系作为选择变极方案、变极接法的依据,得出风机电动机高效率变极设计原则。
Based on the characteristics of motor of fan, taking the maximum efficiency as the optimized object, the interactive restricting relation between air-gap-magnetic-tight, slip ratio, pole-pairs during the pole changing run with high efficiency was established. Based on this relation, the pole change arrangement and pole change connection were selected, and the principle of pole change design with high efficiency for motor of fan was obtained.
