https://www.gwinsys.com/fully-automatic-rotor-production-line.html

A fully automatic rotor production line represents the core of modern motor manufacturing, delivering high efficiency, high precision, and stable output for various electric motor applications. As a leading automation solution provider, Jieyun Intelligent Equipment (Suzhou) Co., Ltd. specializes in designing and manufacturing intelligent rotor assembly lines that integrate robotics, advanced control systems, and automated inspection technologies.

Below is a detailed breakdown of the complete production workflow.

1. Wire Winding (Winding Process)

The production line begins with high-precision coil winding.
Automated winding machines ensure consistent tension control, uniform turns, and accurate wire positioning. Servo systems and real-time monitoring reduce wire deformation, improve electrical performance, and guarantee consistency across rotors.
This step forms the foundation for motor efficiency and reliability.

2. Lamination Stacking

The next stage involves automatic lamination stacking, where steel laminations are precisely aligned and layered.
Advanced feeding systems and positioning modules ensure:

• Accurate lamination orientation

• Tight stacking tolerances

• Improved magnetic performance

Jieyun’s intelligent stacking units support multiple rotor core designs and deliver high structural stability.

3. Press-Fitting and Riveting Operations

After stacking, the rotor undergoes press-fitting and riveting.
Automated hydraulic or servo-press machines apply controlled pressure to secure laminations and prevent displacement. Precise riveting guarantees long-term mechanical strength, reduces vibration, and improves rotor life cycle.
This fully automated section enhances safety and production speed.

4. Dynamic Balancing Calibration

To reduce noise and vibration during motor operation, the rotor is subjected to dynamic balancing correction.
High-speed balancing machines measure and automatically compensate unbalanced mass by drilling, milling, or adding counterweights.
This step ensures:

• Smooth motor operation

• Extended bearing lifespan

• Higher energy efficiency

5. Drying, Potting, and Dispensing

For insulation and mechanical reinforcement, the rotor enters a controlled drying and potting/dispensing process.
The production line integrates:

• Automated epoxy dispensing

• Precise glue volume control

• Real-time curing temperature regulation

This ensures optimal adhesion, improved insulation, and enhanced rotor durability in high-temperature environments.

6. Shaft Pressing

The rotor shaft is then pressed into the core using servo-controlled pressing equipment.
Key performance features include:

• Accurate pressing force monitoring

• Position tracking

• Zero-damage interference fit

The automatic shaft-pressing module provides stable assembly quality and high repeatability.

7. Automated Inspection Systems

Before entering final packaging, each rotor undergoes a comprehensive quality inspection.
The integrated inspection station includes:

• Dimensional measurement (diameter, length, concentricity)

• Weight verification

• Concentricity evaluation

• Visual defect detection via CCD/AI

All data is recorded through MES or industrial IoT systems, ensuring full traceability and quality consistency.

8. Final Product Packaging

The final step of the line is automated packaging.
The system supports:

• Automatic counting and sorting

• Protective packing materials

• Labeling and traceability codes

• Palletizing by robotic arms

This ensures safe transportation and minimal manual intervention.

The fully automatic rotor production line developed by Jieyun Intelligent Equipment (Suzhou) Co., Ltd. offers an integrated, high-efficiency solution covering every stage from winding to final packaging.
With advanced automation, intelligent inspection, and flexible modular design, the production line significantly enhances product consistency, reduces labor costs, and supports large-scale, high-precision motor manufacturing.
