A coil winding machine, a coil winding machine is a device that winds a wire-like object onto a specific workpiece. Among the possible malfunctions of a coil winding machine, the short circuit of a coil winding machine is a relatively common phenomenon. Then the coil winding machine will why there will be a short circuit and how to solve it?

1. Occurrence of the cause

The main reasons for the open circuit of the winding machine include: maintenance of the line is torn; manufacturing process problems; winding machine components wire end welding is poor, overheating desoldering; winding machine damaged by external forces; winding machine short circuit grounding, resulting in burning and so on.

II. Detection methods

(1) Observation method. The location of the break point is usually at the end of the winding machine. You can visually check whether the ends of the winder are desoldered.

(2) Multimeter or shaker detection method. Measure the first and last ends of each phase of the winder separately, and the infinite phase is the open-circuit phase.

Power-on detection method. When the motor is running normally, measure the three-phase current with a clamp-on ammeter. If the three-phase current is unbalanced, short-circuit fault can be ruled out.

III. Handling and repair methods

(1). Open circuit to the end, connect it, re-weld it, wrap it with proper insulation, dip it in insulating paint to dry, and then put on insulating sleeve to use it.

(2). Internal winder disconnected. This condition cannot be repaired. The coil of the winder needs to be replaced.

In short, the key to the repair of the winding machine is to identify the cause and location of the fault as soon as possible according to the fault phenomenon. These troubleshooting methods have no strict boundaries in practical use. Sometimes only one method can be used to eliminate the fault. Multiple methods may be needed at the same time.
