Short circuits in stator winding machines are one of the common defects of such machines. When the stator winding machine detects a short circuit, it will stop immediately, and then conduct inspections and repairs. So how should the short-circuit problem in stator winding machines be addressed? First, let’s take a look at what a winding machine short circuit is and its effects. If a broken wire is detected in the stator winding machine, it is referred to as a short circuit in the winding machine, which is the cause of a missing phase inside the motor. When disconnecting a wound-rotor machine, there are a series of electrical timing issues, such as difficulty in starting, unbalanced three-phase currents, abnormal vibration, excessive temperature rises beyond controllable levels, and smoking and burning of the windings. Imagine it. (1) Causes The main reasons for short circuits in stator winding machines include: the circuit being disconnected during maintenance ； Problems during the manufacturing process ； The wire ends of the stator winding machine are poorly welded, overheated, and not properly bonded ； The winding machine was damaged by external forces ； The stator winding machine short-circuited and grounded, resulting in a fire. (II) Testing methods 1. Observation method. The most common location for break points is usually at the end of the winding machine. Visual inspection can be used to determine whether the two ends of the stator winding machine are disconnected. 2. Multimeter or megohmmeter testing method. Measure the beginning and end of each phase winding separately; the infinite phase is the short-circuited phase. 3. Power-on detection method. When the motor is operating normally, use a clamp ammeter to measure the three-phase current. If the three-phase currents are unbalanced and short-circuit defects can be eliminated, the stator winding machine with the smallest current has the drawback of a short circuit. (III) Handling and correction methods: 1. When the end of the circuit is disconnected, reconnect it and weld it firmly again; wrap it with appropriate insulating material and dip it in insulating paint to allow it to dry, after which an insulating cover can be applied before use. 2. The internal stator winding machine has been turned on. Usually, this situation cannot be corrected. It is necessary to replace the stator winding machine coils.
