Hairpin Stator Production Line for Flat 

Wire EV Motors

This fully automated production line is tailored for the manufacturing of hairpin stators 

in flat wire drive motors used in electric vehicles (EVs) and new energy vehicles (NEVs). 

It supports multi-layer stator production (2–10 layers) and meets the demands of high-speed,

 high-efficiency, and high-precision motor manufacturing.

Key Features:

• High Automation & Intelligence: Complete line automation including paper insertion, coil

  forming, insertion, end twisting, welding, testing, and coating processes.

• MES Integration: Enables production data traceability, quality monitoring, and remote control.

• Flexible Configuration: Adaptable for different motor stator specifications and production volumes.

• Compact Footprint: Efficient use of factory space, total layout area only 30m x 12m.

• High Yield & Consistency: Cycle time of 100 seconds per stator ensures stable high-volume output.

Technical Specifications:

• Production Cycle Time (C/T): 100 seconds per stator

• Production Capacity: Suitable for 2 to 10-layer hairpin stators

• Line Dimensions: 30 meters × 12 meters

• System: Fully integrated with MES (Manufacturing Execution System)
