如果定子电压波形中的高次谐波成分相对较低，像在6阶梯波中那样，谐波铁损增加不会超过10％。如果铁损和杂散损耗占电机总损耗的40％，则谐波损耗仅占电机总损耗的4％。摩擦损耗和风阻损耗是不受影响的，因而电机的全部损耗增加小于20％。如果电机在50Hz正弦电源时的效率为90％，则由于谐波存在使电机效率只降低1％一2％。 如果外加电压波形的谐波成分明显地大于6阶梯波时的谐波成分，则电机的谐波损耗将大大增加，而且可能大于基波损耗。就是在6阶梯波电源时，一个低漏抗的磁阻电机可能吸收一个很大的谐波电流，从而使电机的效率下降5％或更多。在这种情况下，为了满意地运行，就要使用12阶梯波的逆变器，或采用六相的定子绕组。电机的谐波电流和谐波损耗实际上与负载无关，因此时间谐波的损耗大小实际上可以在空载情况下用正弦电源和非正弦电源进行比较确定。以此来确定某种型式或某种结构的电机效率下降的大致范围。深圳兴丰元机电专业生产和销售步进电机、步进电机驱动器、伺服电机、伺服驱动器，代理日本多摩川伺服、东元伺服、德科斯(TKS)行星减速机以及运动控制产品。自主研发有攻丝机伺服电机。
