Damage to the motor insulation of the stator winder may cause a short circuit in the stator winder. If a short circuit occurs in a stator winding machine, the motor may not be able to operate normally due to a surge in power flow. Overvoltage, undervoltage protection, overload, phase breakage and mechanical equipment damage that occurs during the operation of the winding machine can cause a short-circuit fault in the stator winding machine. Stator winding machine short-circuit fault occurs mainly in the form of inter-turn and inter-phase.
The specific cause of short-circuit fault in the stator winding machine may be caused by a variety of factors. For example, if the stator winding machine has been operating under load, then its insulation will be faded, that is, a short-circuit fault. In addition, if the stator winder is operated under high humidity for a long time, the grounding effect will be affected by moisture return.

Improper or damaged insulation on the top or solid layer of the stator winder can also cause a short circuit. Insulation penetration from lightning strikes, metal parts or microorganisms that get inside the motor can cause a short circuit in the stator winder. To deal with the stator winding machine short-circuit fault first must find the cause of the fault, according to the observation method, the motor will be dismantled, check the motor components are not thick smoke, mold condition. If the stator winding machine has a short circuit, there will generally be a fire caused by the fire will burn insulation, the occurrence of such marks is generally the part that produces a short circuit.

You can also apply a submerged ammeter to check the three-phase current, if the flow of electricity in one of them is much higher than the other, then it is a long indication that this phase has a short circuit. Can also apply a multimeter or shaking table to check, check the case of the first stator winding machine coil external wiring, correctly connected to the multimeter or shaking table, the R × 10KΩ file to measure the same phase or both sides of the two phases, if the reading value is abnormal, the standard value is very low, it shows that in the middle of the two phases of this phase winding machine has a short circuit condition exists.

Short-circuit problem occurs in the stator winding machine edge of the part, can be insulated in the part of the fault solution, and then again wrap the line, dipping paint, followed by a good dry solution work can be. If the problem is in the slot on the line, the first part of the problem must be found in the insulation repair, and then placed in the wire slot, infiltrated into the three-proof paint after air-drying solution. Most of the conditions between the phase short circuit can not be repaired, the only way to remove and replace the winding machine equipment.
