vertical winding machine

Unlike horizontal transformer winding machine where the main shaft is parallel to the ground, vertical winding machines have the main shaft perpendicular to the ground. The coil is wound on a horizontally rotating disc. Taking advantage of the optimized gravity distribution and the convenience of axial compression, vertical transformer winding machine is mainly used to wind high and low voltage coils, continuous, tangled, or spiral coils for transformers that are extremely heavy and large in size.

BEST™ vertical winding machine

As a leading manufacturer deeply rooted in the transformer manufacturing equipment field, BEST™ vertical winding machines have abandoned the crude control methods of traditional equipment, and deeply integrate high-precision mechanical transmission with digital closed-loop algorithms, specifically developed to overcome the challenges of radial deflection, tension distortion, and dimensional tolerances during the winding of heavy coils weighing tens of tons. We not only provide standardized vertical winding machines, but also turnkey projects covering the entire lifecycle, from factory planning and equipment selection to after-sales maintenance.

features

BEST™ vertical winding machine’s spindle drive utilizes a high-power variable frequency servo motor paired with a high-precision planetary reducer, while the core rotating component at the bottom employs a large, high-precision, heavy-duty slewing bearing. Even at extremely low speeds (such as 0.1 r/min) and under extreme conditions with loads reaching tens of tons, our equipment can still output a constant, pulsation-free, powerful torque. The end face runout and radial runout of the winding disc are strictly controlled within the micrometer level, ensuring absolute precision in the height and concentricity of the coil winding.

  • High-torque smooth output technology
  • Zero-deflection heavy-duty support structure
  • Axial clamping auxiliary system
  • Intelligent follow-up and efficient positioning
