有刷和无刷电机之间最明显的区别是是否配置有常见的电刷-换向器(Brush-Commutator).过往一个世纪以来,有刷直流电机的换向一直是通过石墨电刷与安装在转子上的环形换向器相接触来实现的.
而无刷电机则通过霍尔传感器(Hallsensor)把转子位置反馈回控制电路,使其能够获知电机相位换向(顺序)的正确时间.大多数无刷电机生产商生产的电机都具有三个霍尔效应传感器.由于无刷电机没有电刷,故也没有相关接口,因此更干净,声学噪声更小,事实上无需维护,寿命更长.
那么,还有什么是有待更进一步的呢?尽管电机业对无刷电机上风的熟悉日益加深,但迄今工作仍只限于开发上述的无刷电机霍尔传感器控制电子元件.

只要用清水漂洗水龙头即可，再用软棉布抹干水龙头。使用下列清洁剂去除粗实面膜和堆积物：温和液态玻璃清洁剂、纯清液态玻璃清洁剂、不含酸，无磨损性柔和液体或完全溶解的粉未、无摩擦性溶液擦光剂。切勿使用任何摩擦性清洁剂、布或纸布；切勿使用任何含酸的清洁剂、抛光摩擦剂或粗糙清洁剂。在水压不低于.2mpa（即.2kgf／cm2）的情况下，在使用一段时间后，如发现出水量减小，甚至出现热水器熄火的现象，则可在龙头的出水口处轻轻拧。

硬密封蝶阀六大防护措施：1.阀盘上焊接的螺栓不宜太长，否则会因为螺栓过长而抵住阀体内流道，造成密封面被架空，不能发挥密封作用；组装时应注意检查调整丝杆开度，保证密封面能紧密接合。选择合适的调整垫，衬垫厚度应稍低于或等于阀盘密封面台阶高度，使软密封垫与阀盘密封面紧密贴合，处于同一个平面。为防止压紧螺母脱落，螺母旋紧后应作适当的防松处理。应考虑流体介质使用条件，选择适合介质要求的软密封垫，以免出现介质腐蚀或高温变形等影响使用。
