转矩脉动是机电伺服系统的困扰,它使的位置控制和高性能的速度控制很困难。在高速情况下，转子惯量可以过滤掉转矩波动。但在低速和直接驱动应用场合，转矩波动将严重影响系统性能，将使系统的精度和重复性恶化。而空间精密机电伺服系统绝大多数工作在低速场合，因此电机转矩脉动问题是影响系统性能的关键因素之一。 PMSM和BLDCM都存在转矩脉动问题。转矩脉动主要有以下几个原因造成：齿槽效应和磁通畸变、电流换相引起的转矩及机械加工制造引起的转矩。 ? 齿槽效应 在永磁电机的电枢电流为零的情况下,当转子旋转时,由于定子齿槽的存在,定子铁芯磁阻的变化产生了齿槽磁阻转矩,齿槽转矩是交变的, 与转子的位置有关,它是电动机本身空间和永磁场的函数。在电机制造上,将定子齿槽或永磁体斜一个齿距, 可以使齿槽转矩减小到额定转矩的1% -2%左右。或者采用定子无槽结构，可以消除齿槽效应，但这些方法都将降低电机的出力。PMSM和BDLC中的齿槽转矩脉动没有明显的差别。 ? 磁通畸变和换相电流畸变引起的转矩脉动 磁通畸变和电流畸变是指PMSM中气隙磁场、反电势和电枢电流是非正弦波，BLDCM中气隙磁场和反电势非梯形波，电枢电流是非矩形波。气隙磁场和电枢电流相互作用后会产生转矩波动，反电动势与理想波形的偏差越大, 引起的转矩脉动越大。

此时可以打开旋涡气泵的外壳，清理内部杂物。在橡胶皮上钻一个小孔，排除负压产生的吸附作用即可。电机的缺相或运转方向不对也是造成此类故障的一个原因，此时应检查并重新接好电源，如果电机烧坏，应更换同型号电机，单相电机检查电容是否完好，接线是否正确。对气泵噪声变大时进行的维护首先检查风力士旋涡气泵泵体内是否有杂物，如有，则打开外壳,清理内部杂物；其次检查叶轮是否卡住，此时联系厂家修理，需要重新装配才能消除故障。

对于暖气和暖气管道，您同样要谨慎从事，因为暖气在室内的位置，直接影响到冬季室内的温度。如果拆改不当，不是取暖受影响，就是暖气跑水。原有的钢窗：有些住户因为原有的钢窗不好看，就换了铝合金窗。由于目前少数装饰公司为了图便宜采用小规格的型材，或干脆以次充好所以有些铝合金窗的坚固程度远远逊于钢窗。使用这样的铝合金窗容易造成脱落，在高层建筑上尤其如此。装修中不能使用的建筑材料不能使用有污染的材料：有些材料含有对有害的化学物质，这些材料就不能用。
