The motor winding short-circuit fault is a short-circuit phenomenon formed between winding turns or an insulation damage between different winding.Three-phase asynchronous motorAfter the occurrence of this phenomenon, the three-phase current unbalance, noise and vibration will occur. Senli Motor Xiaobian will take you to understand the inspection method of short circuit fault in the lower winding.

       formThree-phase asynchronous motorThere are many reasons for winding short circuit, such as overload, excessive current, single-phase operation will cause winding short circuit; We can make the motor run with no load20minAround, check whether the winding smoke phenomenon, if the short circuit turns less smoke will not occur, and then disassemble the motor, the hand induction, generally a short circuit winding will be relatively hot, find the fault point;

       Megohm meter can also be used to test, if the resistance value is very low, then the two phases have short circuit phenomenon; It can also be measured in idlingThree-phase asynchronous motorIf a phase of the current is found to be larger, then it may be the cause of the short-circuit fault; Some will measure the three-phase voltage imbalance, at this time because it is used to exchange the two-phase power supply method to test, if the current will not change with the power supply exchange, then it can be concluded that the current is too large a phase winding may have a short circuit fault.
