Robot joint motor, stator winding commonly used precision winding equipment, stator is characterized by multi-slot, multi-line and winding, the choice of winding machine is very important, robot brushless motor winding machine how to choose? Vacuz give you an introduction to what details to pay attention to multi-line and winding!

First, the selection of robotic brushless motor winding machine considerations

1. Stator slot direction

Slot inward: suitable for the selection of professional precision winding machine, this type of equipment adopts advanced control system, can efficiently complete the stator coil winding work.

Slot outward: It is more suitable to use flying fork external winding machine, which is designed for stator or rotor products with slots facing outward.

2. Stator inner and outer diameters

Outer diameter: The outer diameter of stator for brushless miniature winding machine is usually between Φ20~Φ130mm. If the stator exceeds this range, it will be more difficult to wind and may need to be customized off-standard. At the same time, the larger the outer diameter, the larger the winding space required, and the number of stations will be reduced accordingly. Therefore, according to the specific size of the stator outer diameter, the appropriate number of stations should be selected to optimize the winding efficiency.

Inner diameter: The inner diameter of stator usually ranges from Φ12 to Φ100mm.

3. Stator stack thickness (height)

Stator stack thickness is generally required to be between 5~80mm. For the stator with high stack thickness, special attention should be paid to the effect of stator height on the way of swinging needle and wire crossing to prevent scraping, wounding and breaking of wire.

4. Enameled wire diameter and material

Wire diameter: Stator with thin wire diameter (e.g. about 0.1mm) can be selected for high speed winding machine to improve efficiency; while stator with thicker wire diameter (e.g. more than 1.0mm) needs to be configured with tension control system and precision winding machine to ensure the tightness and stability of the coil.

Material: Commonly used enameled wire materials include copper wire, aluminum wire and iron wire, etc. Different materials require different configurations of winding machines.

5. Winding method

Single wire winding: applicable to motor stator with large wire diameter or low requirements, with lower requirements on the configuration of the winding machine, but the winding efficiency is relatively low.

Multi-wire parallel winding: Applicable to the demand of improving the performance and power density of the motor, which needs to be equipped with accurate tension control, synchronized winding function and complicated wire arranging system.

6. Other Factors

Equipment stability, durability, ease of operation and after-sales service are also important factors to consider when selecting a winding machine.

Precautions for parallel winding of multiple wires

1. Tension control

When winding multiple wires together, it is necessary to ensure that each wire is subject to uniform tension to avoid loose wires or cross confusion. Therefore, an accurate tension control system should be equipped for real-time monitoring and adjustment.

2. Synchronized Winding

All wires need to be wound on the stator synchronously to maintain the uniformity and stability of the coil. Therefore, it is crucial to choose a winding machine with synchronized winding function.

3. Wire Arrangement System

A sophisticated wire arrangement system ensures that multiple wires do not cross each other or get confused during the winding process. Choosing a winder with an advanced winding system improves the quality and efficiency of the winding process.

4. Crossing method

Selecting the appropriate wire crossing method to minimize the damage to the wire. Common wire crossing methods include direct crossing, guide wheel crossing, tension crossing, and so on. When choosing, we need to consider the impact of the wire crossing method on the degree of damage to the wire, winding efficiency and quality.

5. Speed control

For multi-wire winding, especially when the wire diameter is thicker or the stator height is higher, the winding speed should be reduced to avoid wire damage and wire breakage.

6. Auxiliary accessories

The quality and adjustment of auxiliary accessories, such as tensioner, over-winding wheel, wool felt, wire nozzle, etc., are also critical. They should meet the requirements, especially the material and shape of the nozzle should be adapted to the characteristics of the wire and winding requirements.

In summary, when selecting a robotic brushless motor winding machine and carrying out parallel winding of multiple wires, it is necessary to comprehensively consider stator parameters, equipment configuration, stability, durability and other factors to ensure the quality and efficiency of the winding. I hope this information can help you.
