Automatic Synchronous Motor Coil Manufacturing Line

1. Project Background: High-Demand Home Appliance Motors

The Permanent Magnet Synchronous Motor (PMSM), specifically the TYJ/MTY Series (Claw Pole type), is the "hidden hero" in home appliances. It powers the oscillation of fans, the turntables of microwaves, and the air guide louvers of air conditioners.
Our client, a leading motor manufacturer, faced a challenge: manual assembly was too slow and inconsistent to meet the booming market demand. They needed a Turnkey Automation Solution to produce 15,000+ motors per day with zero defects.

2. The SIPU Solution: A Fully Integrated Assembly Line

SIPU engineered a custom Automatic Synchronous Motor Coil Manufacturing Line that replaces 8-10 manual workers. The line integrates the following key processes:

• Step 1: Precision Winding (Multi-Spindle): High-speed winding onto the bobbin with active tension control to ensure stable resistance.

• Step 2: Terminal Soldering: Automatic fluxing and soldering of the coil pins, ensuring reliable electrical connectivity.

• Step 3: Stator Assembly (Claw Pole Pressing): The core technology. The machine automatically aligns and presses the upper and lower metal claws (yokes) to encapsulate the coil, forming the stator.

• Step 4: Quality Testing: Integrated Resistance, Inductance, and Hipot testing stations automatically screen out NG parts.

3. Key Advantages of This Line

• Versatility: Compatible with various motor sizes (e.g., 49TYJ, 50TYJ) with quick fixture changeover.

• Labor Saving: One operator can manage the entire line, significantly reducing labor costs.

• High Consistency: Automated assembly ensures every motor has the exact same dimensions and performance, crucial for automated appliance assembly lines.

4. Client Result

After installing the SIPU line, the client achieved a 40% increase in production capacity and reduced the defect rate to under 0.1%. This successful case proves SIPU's expertise in providing Motor Manufacturing Automation solutions.
