摘要
为消除高温超导电机定子齿谐波以及其它高次谐波引起的转子高温超导磁体发热失超和临界电流降低等不良影响,通常在外转子加一电磁阻尼屏,用以屏蔽这些高次谐波,保障高温超导电机的安全运行。本文以某高温超导电机为例,采用场路耦合时步有限元法对齿谐波以及电枢反应引起的高次谐波在转子结构件中产生的涡流损耗进行计算,分析了电磁阻尼屏厚度与磁屏蔽效果的关系,同时计算了磁性槽楔对转子结构件涡流损耗的影响。
To get rid of such some adverse effects of quenching of high temperature super-conductor （HTS ） in rotor and decreasing critical current caused by tooth harmonic wave and high harmonic wave, electromagnetic damping barrier usually is added out of external rotor so that these high harmonic wave is shielded, which makes sure HTS motor reliably operate. In this paper, a HTS motor is taken as an example, by using time-stepped finite element method coupled field and circuit, eddy current loss caused by tooth harmonic wave and high harmonic wave is calculated and analyzed exactly in the rotor steucture, the relation of the thickness of electromagnetic damping analyzed, and the effects of magnetic slot wedee on eddv barrier with magnetic screening effectiveness is current loss in rotor structure are calculated.
