When a wire breakage fault occurs in the winding machine, it is called a wire breakage in the winding machine, which is a situation of internal phase loss in the motor. When there is a circuit break in the winding machine, the motor will experience a series of faults, ranging from difficulty in starting, unbalanced three-phase current, abnormal vibration, to temperature rise exceeding the controllable range, smoking, and burning of the winding machine. Below, Dongguan Wuyu Electronics Co., Ltd. will explain to you the solutions to the wire breakage fault of the winding machine.
Cause: The circuit was torn during maintenance; Manufacturing process issues; Poor welding of wire ends in various components of the winding machine, overheating and desoldering; The winding machine is damaged by external force; Short circuit and grounding of the winding machine, resulting in burning, etc.
Detection method:
1. Observation method. The most common location for breakpoints is usually at the end of the winding machine, and it can be visually checked to see if there is any desoldering at both ends of the winding machine.
2. Power on detection method. When the motor is running normally, clamp ammeters are used to measure the three-phase current. If the three-phase current is unbalanced and the short circuit fault can be eliminated, the winding machine with the minimum current has an open circuit fault.
3. Multimeter or shake meter detection method. Measure the front and rear ends of each winding machine separately, and the infinite phase is the open circuit phase.
Handling repair methods:
When the circuit breaker is at the end, it should be reconnected and re soldered, wrapped with appropriate insulation and soaked in insulation paint to dry, and then covered with insulation sleeve for use.
2. The internal winding machine has a broken circuit, which cannot be repaired and the winding machine coil must be replaced.
