Although the standardized use of winding machines has been repeatedly explained, there are always careless mistakes, such as incorrect connections to the winding machine. What is the effect of a wrong connection of a winding machine? How can it be detected? Vacuz also consulted with maintenance supervisors. They have their own view on the maintenance of the winding machine.

Winding machine reverse connection detection

1. Ball method. The correct connection of the winding machine depends on whether the small steel ball can roll along the inner surface of the stator.

2. Multimeter detection method. Use a multimeter to test according to the wiring diagram. As long as there is no reading on the multimeter, there will be a reverse connection on the winder.

Handling method

If the exported end is wrong, the head and tail should be judged correctly before connection.

If individual coils or groups of coils are inverted, the coils need to be replaced, dipped in insulating paint and then dried.

According to the characteristics of the inverted current surge, find out the wrong connection of the winding machine to deal with.

If the y connection to the △ no-load current will be large and needs to be corrected in time.
