　　上图电路就是星三角降压启动的主回路。这里面要说一下，多大功率的电动机要用降压启动呢。有好多朋友说7.5KW以上就要降压启动，也有说11KW的，还有说15KW的。还有的朋友说，他们厂的55KW的电机还是直接启动呢。那么哪个是对的呢。

　　洛伦兹力和安培力并不矛盾，之间可相互推导。安培力和洛伦兹力的方向，都是通过左手定则来判定的。磁通量是标量，但有正、负，正、负 不代表方向，仅代表磁感线穿入或穿出。同学们能不能想到其他类似的物理量呢。比如，电流，也是有“运动方向”的标量。

　　电阻的另一种形式是“膜电阻”，由于继电器的触点长期在空气中，总有灰尘、水汽、化学气体产生的化合物，都会黏附在触点上形成一层很薄的薄膜，这就是所谓的“膜电阻”；这样触点的导电性就很差了，严重时甚至不导电。

　　这类电动机的二次绕组中大多串接有离心式启动开关，正确接线时，启动电容应和离心式开关串联，再和运行电容进行并联。单相双电容电动机的正确接线方法如图所示。当电动机启动以后，一旦电动机的转速达到额定转速的80%左右时，离心开关的触点就会断开，从而切断了启动电容与电路的连接，此时电动机电流减小，电动机进入了正常的运行状态。

　　通常有两种提法：一种为要求对某一给定带外频率fs抑制多少dB，计算方法为fs处衰减量As-IL；另一种为提出表征滤波器幅频响应与理想矩形接近程度的指标——矩形系数（KxdB>1），KxdB=BWxdB/BW3dB，（X可为40dB、30dB、20dB等）。

 　　2.控制回路采用24V作为额定控制电压时，应采用并联型触点，以其工作可靠性。3.控制回路必须用低电压控制时，以采用48V为优。大容量器可利用中间继电器控制，以进一步工作可靠性。4.控制回路采用220V及以上电压作为额定控制电压时，具有高的可靠性。　　 扁孔的，两头的，三角的,大家在日常生活中使用的插线板大多是这类产品，不同类型的开关主要区别于它们的面板尺寸和设计，而家居电路安装一般以86型和118型开关为主，SOK开关都有这两型，各有所长，建议消费者同时选购。
