For the ordinary three-phase asynchronous motor products, we mainly consider the factors of over-load, starting performance, efficiency and power in the design; However, when we design inverter motor products, because the critical slip rate is inversely proportional to the power supply frequency, the critical slip rate can be close1When directly started, therefore, overload capacity and startup performance do not need to be considered too much.

       The following Senli motor Xiaobian will take you to a simple understanding of the troubleshooting of variable frequency motors.

       1.Under examinationYVFVariable speed motorWhen the fault occurs, the detection instrument should be used to find the fault location, and the operation relationship between the line and the inverter motor should be checked again to avoid misjudgment.

       2.After equipment cleaning and maintenance, first clean the buttons, wiring points and contact points, and check whether the external control button is faulty. Many failures are caused by dirty conductive dust blocks. Once a cleaning fault occurs, it is usually eliminated.

       3.Because equipment failure due to assembly component quality or other equipment failure is very common, measurement and repair depends on experience and instrumentation. First of all, do not rush to replace the damaged motor parts inside, and then replace the damaged motor parts after determining the normal equipment circuit.

       4.During overhaul, for electrical equipment that coexists with adjustment and failure, it is necessary toYVFSpeed regulation and frequency conversion motor speed under the premise of adjustment to solve the problem.
