描述
万用表检测电机的方法其实很简单。也就是霍尔传感器的供电及信号线与电机的三条相线绕阻是绝缘的,电阻很大,当电机有进水时,它们之间的绝缘电阻就变小了。因此用万用表的高电阻档就能很方便的测量出电机是否进水。万用表检测电机的方法其实很简单。也就是霍耳传感器的供电及信号线与电机的三条相线绕阻是绝缘的,电阻很大,当电机有进水时,它们之间的绝缘电阻就变小了。因此用万用表的高电阻档就能很方便的测量出电机是否进水。注意以下几点:数值仅供参考企业,会因为进水的程度大小,及进水的时间长短不同而不同。当测不出数值时,即超量程显示时,则表示电机没有进水。另外应当注意的是,当电机引线。用万用表测电机不太可靠,还是用摇表。用万用表测量电机的三个绕组的阻值是否一致。音响中电源滤波器主要是滤除电源中的杂波，使电源输出平滑。这对于小功率电器如CD机，DVD机，前级等的音质有所提高，主要表现在背景静噪方面，如果用在汽车音响方面其效果就比较突出。如果是家用高级HIFI音响，那就千万不要使用电源滤波器，因为它制约了电流的输出，效果反而不好，另外，电源滤波器如果用在视频上，如电视，电脑，投影机等，其图像声音效果一流。
电源滤波器的作用就是减少电源干扰,而电源干扰可以分为两类:普通模式和共通模式。普通模式是两组输入电源线之间的杂讯,这种杂讯通常是在关机和开机时产生。而共通模式是指因为器材接地不良,又或是广播无线电及冰箱马达电磁、日光节能灯镇流器、洗衣机、风扇可控硅调速等引发的干扰！
