The DYJ high and low voltage winding machine winds coils of small and medium transformers. Once the machine is connected to three phase 380V power and the switch is turned on, the operator simply presses the foot switch to start winding. The gearbox uses gear shifting with AC frequency conversion control and rare earth aluminum alloy worm gears for strong wear resistance and reliable self-locking. Shifting is done with the fork handle to reach the required speed, giving steady starting, stable braking and low noise.
