请问
K是什么参数呢? K是在绕组为大小相带时,相带的增减数。在此为60度正规相带,K输入为零即可。 欧阳兄!我还是不会用你的程序,再帮我分析一组接线看看m=3 相
2P=28
Y=4
Z=144
q=1—5/7
循环数:2212212,2212212,、、、、、、、、、、、、 你可以用单元电机来分析,这样就减少了一半的数据输入量,此时槽数为72,极对数为7,其他不变. 按你的循环数输入分析, 在7对极附近有10%左右的5对极反转波,比较严重. 其他的循环数,你可以自己分析. 在槽号输入的数据时,按每行属于同一相的方法输入. 你可以按循环数,将槽号按三相的相属,按A,Z,B,X,C,Y分配, 其中A,B,C分配正槽号,X,Y,Z分配负槽号, 这样每相的槽号就分给了A,B,C三相了 好的,我试试看,不得再联系你哦,方便留个QQ号吗?这样联系比较好点。 我不用QQ号.你可以发邮件给我.

.042 180 按你说的10对极比较12.03736 /1.598662 的确相差很大,FVN在什么值范围可以不考虑它呢?怎样确定正反转波呢? 第一, 14对极具有4.39%的反转波, 说明三相不对称; 另外在14对极的附近存在11,12,13,16... 反转波,其能量都在3%~5%, 相当大,会产生噪音, 说明绕组分配不好. 哎 没看懂 帮顶了
这个可是好贴啊 欧阳兄!你好啊!首先感谢你的帮助,这周去现场改接线的工人回来说,经过该接线后,噪音降低了3个分贝,但是仍然高于国家标准,我看他们带回来的数据,离机座1米处测量数值92分贝。我计算了一下电磁噪音,具体数据如下:

10、π*Da/(2.54*λ)= 3.128
11、空载时电机表面噪声的响度级 L= 65.5 分贝
经过计算,可以看出齿谐波分量很大,所以我打算将槽楔改为磁性槽楔,估计能降低到90分贝以下,不知道大家还有什么降低电磁噪音的高周。 你应该还是要注意定子轭的强度和机壳的强度,甚至要在定子与机壳间考虑隔振或有意的使机壳的谐振点频率与电机的震动频率错开. 1.接线看看(白延年主编)电机设计与计算。
2.若是通用冲片,可考虑斜槽,线圈换位。方法电机设计与计算中有。
3.说的几个小电机我们都生产过,没有你说的问题。 都是高人啊,受教了 看过诸位高手过招,很感兴趣,初学乍到,多指教。
