Xingte revolutionary new Automatic motor stator needle winding machine,needle winder for motor stator coil winding

The INNOVATIVE CONCEPT of the XT-02D Machine is:

FLEXIBLE: able to manufacture different types of stators
CONFIGURABLE: various options are available to make the machine suitable for specific applications
SCALABLE: possibility to increase the number of needle heads or partialize their usage
ERGONOMIC: Designed to grant a high degree of accessibility
NOISELESS: direct drive motion, without any vibration (no belt, no cams, no screws)
SIMPLE TO BE PROGRAMMED: user-friendly machine interface
The XT-02D Alone can be delivered with 2, 3, or 4 needles and can be upgraded at a later time. Designed as a stand-alone machine, it can be integrated into a production line with the appropriate configuration.

DIFFERENT PRODUCT TYPES

The XT-02D Platform can work with the following product types:
• inner straight slot stators
• inner skewed slot stators
• outer stators straight and skewed slot
• upper routing
• lower routing
All these types can be manufactured by simply switching between the different programs and the tooling, whenever a changeover is needed.

TOTALLY INDEPENDENT MOTORIZED WINDING SET

The winding operation is obtained by the interpolation of the needle head with the rotating spindle (winding set).
Each winding set of this machine is totally independent:
• Machine scalability (adding winding set).
• Activation or deactivation of each winding set.
• High dynamic / low inertia.
• Easier alignment of the winding set.
Other features:
• Layering axes for external or internal stator winding (Y axes)
• Wire routing and wrapping (interpolation between X and Y axis)

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.

PROGRAMMING
The XT-02D is delivered with innovative software, conceived to re-program autonomously the machine thanks to a user-friendly interface.

Parameters:
• number of teeth per stator
• indexing error
• trajectory optimization
• vertical stroke

Features:
• error proofing (anti-collision on needle trajectory)
• choice of the optimized trajectory
• teach-in mode available

Product parameter

Main Features

• Flexibility (internal and external rotor)
• Multi-parts winding at the same time
• Freely programmable
• Wire layering
• Freely programmable contacting/wire termination (teach process)
• High filling factors despite required space for needle
• Large wire diameter range
• Freely selectable wire connections even on the lower side of the stator
• Low tooling costs

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.
