I. Deepening Core Requirements for Rotor Parameters

Dimensional Accuracy Control System

1. Dynamic Air Gap Balancing Technology

A laser displacement sensor and piezoelectric ceramic fine-tuning device are used to achieve real-time closed-loop control of the air gap.

2. Concentricity Precision Machining

An air bearing spindle and high-precision encoder are introduced to control the concentricity error between the rotor shaft and the magnet to ≤0.01mm.

3. Stack-Thickness Adaptive Process

Segmented Winding Technology: For rotors with stack thicknesses greater than 200mm, a top-down segmented winding process, combined with dynamic tension control, reduces the wire damage rate from 15% to 0.3%.

Low-Tension Winding System: Utilizing a magnetic levitation guide and force-controlled servo motor, winding tension fluctuations are controlled within ±0.5N, preventing wire deformation.

Material and Process Innovation

1. Magnet Performance Gradient Design

Developing a gradient magnet with high surface coercivity and high core remanence improves motor high-temperature performance. Using this technology, a certain industrial robot motor reduced remanence loss from 8% to 3% at 150°C.

Adhesion Curing Monitoring: Utilizing infrared thermal imaging and ultrasonic testing, the curing degree of the magnet adhesive is monitored in real time to ensure a bond strength of ≥25MPa.

2. Automated Magnet Insertion Process

Vision Positioning System: Integrating a high-resolution industrial camera with an AI algorithm, this system accurately positions the polarity of multi-pole magnets within ±0.3°, increasing magnet insertion efficiency by three times.

Error-Proofing Design: RFID chips are used to identify magnet models, preventing incorrect polarity installation and reducing the error rate from 0.2% to 0.001%.

3. Closed-Loop Control of Magnetization Intensity

Using Hall sensors and a PID algorithm, magnetic flux fluctuation after magnetization is controlled to within ±1%. This technology has reduced torque fluctuation in a drone motor from ±3% to ±0.8%, and tripled output power stability.

Optimized Structural Compatibility

1. Standardized Shaft System Design

Developed modular shaft system components in accordance with ISO/DIN standards, supporting rapid interchangeability of shaft diameters from Φ8 to Φ50 mm, reducing changeover time from 2 hours to 15 minutes.

Keyway Machining Accuracy: Using a form-grinding process, keyway symmetry error is controlled to ≤0.02 mm, preventing transmission jamming.

2. Dynamic Balance Compensation

Developed a machine learning-based balance weight optimization algorithm that controls imbalance to within 0.05 g·mm by adjusting the balance weight position and weight in real time.

II. Process Feature Upgrade Solution

Modularization and Flexible Production

1. Quick Changeover System

Using quick-change fixtures and pre-stored program technology, we can complete a changeover between two product models within 30 minutes.

Digital Tooling Management: RFID tags are linked to the MES system to automatically access corresponding process parameters, reducing manual setup errors.

2. Scalable Production Line Design

The modular architecture supports on-demand expansion. For example, adding two automated assembly cells increases production capacity from 1,000 units/day to 1,800 units/day, shortening the payback period to 1.2 years.

Automated Integration Innovation

1. Full-Process Automated Assembly

Integrating robotic loading, laser welding, and online inspection reduces the number of manual intervention steps from 12 to 2, reducing labor costs by 80%.

2. Intelligent Inspection Technology

Laser Measuring Instrument: Enables micron-level inspection of parameters such as rotor outer diameter and stack thickness, with an inspection speed of 120 units/minute.

Magnetic Polarity Detection: Utilizing a giant magnetoresistance (GMR) sensor array, the inspection speed has increased from 5 pieces/minute to 30 pieces/minute, with an accuracy rate of 99.99%.

High-Precision Control System

1. Precision Drive System

A linear motor and grating scale are used for closed-loop control, ensuring the rotor shaft press-fit position accuracy is within ±0.003mm.

Vibration Suppression: An active damping algorithm reduces the vibration amplitude of the equipment from 0.1mm to 0.02mm, improving assembly stability.

2. Real-Time Data Closed Loop

Integrated multi-sensor fusion technology collects data such as pressure, displacement, and temperature in real time, enabling rapid correction of process parameters through edge computing.

Real-Time Monitoring and Traceability

1. Production Process Visualization

Equipped with an industrial Internet platform, it displays equipment status, production progress, and quality data in real time, generating digital reports.

Early Warning System: Using machine learning models to predict equipment failures, maintenance alerts are issued 48 hours in advance, reducing downtime by 60%.

2. Full Lifecycle Traceability

Using RFID and blockchain technology, we record each rotor’s raw material batch, production parameters, and test data, enabling quality traceability and anti-counterfeiting.

Compatibility and Customization

1. Flexible Production for Multiple Models

We have developed adjustable tooling and adaptive programs to support the production of rotors with outer diameters ranging from 30 to 200 mm and stacking thicknesses of 10 to 300 mm, covering 95% of market demand.

Case Study: A production line simultaneously produces rotors for new energy vehicles, industrial robots, and home appliances, reducing changeover losses from 15% to 3%.
