Introduction

The CNC Ceiling Fan Winding Machine represents a significant technological advancement in the manufacturing of electric motors for ceiling fans. This computer-controlled Automation system has revolutionized production efficiency while maintaining exceptional precision in coil winding operations. Designed specifically for high-volume production environments, these machines combine mechanical engineering excellence with sophisticated digital control systems to deliver consistent, high-quality winding results.

Technical Features with Professional Data

1. Precision Computer Numerical Control System

The machine features a 32-bit ARM Cortex-M7 microprocessor with ±0.01mm positional accuracy and 0.1° rotational precision. The CNC system supports G-code programming and can store up to 500 different winding patterns in its non-volatile memory.

2. Multi-Axis Synchronization

Equipped with 4 servo-controlled axes (X, Y, Z, and θ) that operate with synchronization accuracy of ±5μs. The system uses 20kHz closed-loop feedback from high-resolution encoders to maintain perfect coordination between linear and rotational movements during complex winding operations.

3. Adaptive Tension Control

The machine incorporates a real-time tension monitoring system with 0.1N resolution and automatic adjustment capability. The electromagnetic braking system maintains wire tension within ±5% of the set value (typically 50-200g depending on wire gauge) throughout the winding process.

4. High-Speed Winding Capability

Capable of up to 1500 RPM winding speed with acceleration/deceleration rates of 500 RPM/s². The direct-drive servo motors eliminate backlash and provide torque ripple of less than 2% even at maximum operating speeds.

5. Intelligent Wire Handling

The automatic wire guide system features 0.05mm positioning repeatability and can handle wire diameters from 0.15mm to 1.2mm. The machine includes automatic wire cutting and stripping with ±0.3mm length accuracy.

6. Thermal Management System

Integrated temperature control maintains critical components within ±1°C of the optimal 25°C operating temperature. The system monitors 12 thermal sensors distributed throughout the machine and can automatically adjust cooling fan speeds.

7. Quality Assurance Features

The machine performs real-time turn counting with 99.99% accuracy and includes automatic continuity testing at 100V DC with 1MΩ minimum insulation resistance verification. The vision inspection system checks coil geometry with 0.02mm dimensional tolerance.
