Being an electrician, you could only look forward to coming across with a wide variety of complicated electrical circuits and drivers which will later break down and malfunction. Sooner or later, you will be an expert in fixing the said devices. But now that you are yet a starter, it is an ideal thing to know of some practical measures to solve those problems. Please proceed onto reading if you want to get started.
In industrial plants, you will find the solid-state electronic AC motor drive widely used. It can control a wide array of electrical devices like mixers, pumps, machine tools, conveyors, chillers and also air handlers. It may also control all other device that are used to be powered by DC. As is usually the case, the said damages on electrical devices are caused by the rectifier section, so it makes sense for an electrician like you to develop understanding on transistors, insulated gate bipolar transistors, diodes, and silicone controlled rectifiers.

When it turns to AC drives, the most commonly utilized are the pulse width modulated inverter drives. It functions by converting the AC line voltage into a DC and then constructed again to become a variable frequency as well as a variable voltage output. Changing of frequency usually results to a variation in the motor speed. In order to maintain the motor torque, the volts-to-frequency ration is set at a constant.
Now, how do you troubleshoot motor drives? Because most of the failures in the power section and not in the circuit boards, that will not be so difficult to fix. The ordinary plant maintenance technician will not so much be exposed to drive failures which is why mastering in repairing circuit boards may not be easy to attain. A methodical approach has to be utilized in order to effectively and successful repair a troubled variable frequency drive or VFD. If you know that you only possess limited knowledge about the device, then you put into use the method taught in many technical schools – divide-and-conquer.

You have to bear in mind that an excellent troubleshooter is one who sets aside first the section or box that is not passing then signal, and once done, begins on the work. It is even more necessary to remember that in the realm of troubleshooting a dead VFD quickly and effectively, you have to think of safety ahead of time. Even when capacitors are unplugged, they can retain dangerous charge that are harmful.
