IPM电路板包含驱动和缓冲电路，以及过电压、缺相等保护电路。从逻辑控制板来的PWM信号，通过光耦合将电压驱动信号输入IPM模块，因而在检测模快的同时，还应测量IPM模块上的光耦。 4.冷却系统冷却系统主要包括散热片和冷却风扇。其中冷却风扇寿命较短，临近使用寿命时，风扇产生震动，噪声增大最后停转，变频器出现IPM过热跳闸。冷却风扇的寿命受陷于轴承，大约为10000～35000h。当变频器连续运转

特点工控机通俗的说就是专门为工业现场而设计的计算机，而工业现场一般具有强烈的震动，灰尘特别多，另有很高的电磁场力干扰等特点，且一般工厂均是连续作业即一年中一般没有休息。因此，工控机与普通计算机相比必须具有以下特点： 1）机箱采用钢结构，有较高的防磁、防尘、防冲击的能力。 2）机箱内有**底板，底板上有PCI和ISA插槽。 3）机箱内有专门电源，电源有较强的抗干扰能力。 4）要求具有连续长
