Xingte automatic needle motor winding machine for with dual work station XT-02D

Needle Winding:
Needle winding is a preferred method for producing internally or externally wound stators or rotors with intricate winding patterns and pole chains, such as Singletooth Winding.

In the needle winding process, a needle (nozzle) that dispenses wire moves horizontally or vertically along the pole, encircling it as it winds the wire.

This method offers a high level of flexibility in handling various products and processes compared to other techniques. Xingte's needle winding machines can handle multiple products simultaneously, achieving high operating speeds while maintaining process reliability.

Xingte offers a range of needle winding machines tailored for specific products, including machines for winding 2-pole stators or cam-operated winding machines that use multiple needles simultaneously to maximize throughput.

WIRE GUIDE TUBE POSITIONING

Wire guide tube positioning is an important aspect of XT-02D's basic configuration. By default, the wire guide tube is fixed horizontally. However, as an optional feature, a motorized tilting movement can be applied to allow for both upper and lower routing, making the wrapping and routing operations much simpler. This tilting movement can be programmed to any position between +90° to -70°.

Needle Winding

Needle winding is the process of choice for the production of internally or externally wound stators or rotors with a complex winding scheme and pole chains (see Singletooth Winding).

During the needle winding process, the needle (nozzle) that feeds the wire is moved horizontally or vertically along the pole. It thereby "circles" the pole and winds it.

In terms of the products and processes to be handled, this method offers a comparatively high degree of flexibility compared to others. The needle winding machines from XINGTE are able to process several different products simultaneously in one and the same machine. They achieve very high operating speeds by exploiting the physical possibilities without negative effects on process reliability.

XINGTE provides a wide variety of needle winding machines required for special products, e.g. for winding 2-pole stators or cam-operated winding machines where several needles can be used simultaneously to enable maximum throughput.

TENSIONER CLOSED TO NEEDLE

A correct wire tension is essential to grand winding quality. The best way to do this is to install the tensioners close to the winding process. For this reason, XINGTE designs their machines with tensioners next to the needle.
Moreover, it is possible to have two different types of tensioners for each head to manage two different wire tension ranges. This option allows fast retooling and also the winding of an extended wire range.

Product parameter

The stator is stationary during winding. All needle movements are motorized and programmable and managed in direct drive mode (no cam system, no belts, no lead screw).

It is possible to wind:

• Inner straight slot stators
• Inner skewed slot stators
• Outer stators straight and skewed slot

Product parameters

Different tooling configurations are available, on request, to make the machine suitable for all applications.

WINDING SPEED DIAGRAM

The head speed can reach up to 1200 rpm, in particular conditions of stator geometry and wire size.
