What are the configurations and requirements of the motor stator needle-type inner winding machine? How to find a high-quality inner winding machine

Brushless motor stator winding requires the use of winding machine equipment. In addition to the external winding machine, the commonly used winding machine equipment is the internal winding machine. The internal winding machine is mainly used for stator products with inward slots. So what are the configurations and requirements of the motor stator needle-type internal winding machine? How to find a high-quality inner winding machine? Let’s briefly introduce Vacuz to you!

1. Core configuration requirements

1. Adaptability of stator parameters

Outer diameter and inner diameter range: The standard model needs to cover Φ20-Φ130mm outer diameter and Φ12-Φ100mm inner diameter. If it exceeds, it needs to be customized.

Stack thickness control: The stack thickness (stator height) needs to be within 5-80mm, and high stack thickness needs to be customized.

Notch distance: When the wire diameter is ≤0.1mm, the notch distance is 2.5-3mm. For thicker wire diameters, the notch distance needs to be increased to avoid scratches.

2. Winding process accuracy

Wire diameter range: single wire needs to support Φ0.08-Φ1.3mm, and multi-wire winding needs to accurately control the tension. Vacuz brushless motor inner winding machine supports 0.1-1.2mm wire diameter and is suitable for multi-pole motors.

Winding method: Needle-type up and down movement winding needs to be equipped with a servo transmission structure to ensure the needle trajectory accuracy is ±0.02mm and avoid coil deformation.

Wiring system: Multi-station design (such as four-station) can wind multiple stators at the same time to improve efficiency. The efficiency of Vacuz brushless motor internal winding models is increased by 30%, and the coils are arranged neatly.

3. Automation and intelligence

Control system: PLC or touch screen operation, supporting turns, steering, and trimming angle programming.

Tension control: Precision tension system (such as magnetic powder tensioner) ensures that thick wires are wound tightly and thin wires avoid breakage.

Full process automation: no manual intervention is required from online to unloading.

4. Structure and stability

Spindle direction: The longitudinal spindle is adapted to multi-pole motor winding to reduce vibration.

Air source and power supply: 0.5-0.7MPa air source pressure, 380V three-phase electricity, power range 2-26KW are required to ensure high-speed operation stability.

Materials and processes: Key components (such as needles, guide wheels) require heat treatment or precision grinding, and the MTBF (mean time between failures) reaches more than 8,000 hours.

2. Selection criteria for high-quality equipment

1.Technical strength and patents

Give priority to manufacturers with more than 10 winding technology patents to ensure equipment innovation.

2. Industry experience and cases

More than 10 years of industry experience, accumulated multi-scenario solutions.

3. Service system and response

Full life cycle services: including installation and commissioning, operation training, “three guarantees” warranty (2 years for the complete machine), and regular maintenance.

Customization capabilities: whether the equipment structure can be adjusted according to special-shaped workpieces or special processes.

4. Cost-effectiveness and certification

Price comparison: With the same configuration, Vacuz equipment is 5%-10% lower than the market price, making it suitable for cost-sensitive customers.

Certification standards: Passed ISO9001, CE, TUV and other certifications to ensure that the quality meets international requirements.
