The utility model discloses a low -harmonic -wave winding is applied to the three -phase asynchronous motor of 36 grooves 4 utmost point, and the winding adopts double -deck concentric winding to distribute, and its three -phase winding span is 975 or 864. The utility model discloses low -harmonic -wave winding can effectively reduce the electric magnetic vibration and the noise of motor, eliminates higher harmonic basically, has reduced stray loss and has improved the performance. The utility model discloses winding all higher harmonic content except that tooth harmonic are less than 5% of ordinary winding, are particularly suitable for being applied to the occasion that has the strict demand to motor vibration, noise to and improve the inverter motor's under the variable frequency powersupply power supply performance. 本实用新型公开了种低谐波绕组，应用于36槽4极的三相异步电动机，绕组采用双层同心式绕组分布，其三相绕组跨距为9/7/5或8/6/4。本实用新型低谐波绕组可以有效降低电机的电磁振动和噪声，基本消除高次谐波，降低了杂散损耗改善了性能。本实用新型绕组除齿谐波之外的所有高次谐波含量小于普通绕组的5％，特别适合应用于对电机振动、噪声有严格要求的场合，以及改善变频电源供电下的变频电机的性能。
