摘要
为了研究过盈配合加工对非晶合金永磁电机铁耗的影响,采用实验方法测试了多种过盈量时非晶合金材料的损耗特性,并对实验结果进行了分析。给出了考虑过盈配合加工的非晶合金电机铁耗计算方法,并通过样机实验对铁耗计算结果进行了验证,进而分析了不同过盈量时非晶合金电机铁耗的变化规律。结果显示,过盈配合加工会导致非晶合金材料涡流损耗增加,非晶合金电机轭部损耗增加、温升升高、效率降低。在非晶合金电机定子铁心装配时应采用尽可能小的过盈量或不采用过盈配合工艺。
In order to research the influences of shrink fitting process to the iron losses of amorphous alloy permanent magnet motor, experimental method was adopted to measure the loss characteristics of amor- phous alloy material at several shrink ranges, and the results were analyzed. The iron losses calculation method of amorphous alloy motor was given which is in consideration of the influences of shrink fitting process. The calculated results were verified by measured results of an amorphous alloy motor, and the influences of shrink fitting process to amorphous alloy motor was analyzed. The results show that, the eddy current part of amorphous alloy material and the yoke loss of amorphous alloy motor increase a lot because of the shrink fitting process,which leads to a increasing of temperature raise and decreasing of efficiency performance. So, the shrink range should be as small as possible or the shrink fitting process is not used during the casing of amorphous alloy motors.
