Electric scooter hub motor assembly line
Electric Scooter Hub Motor Assembly Line
1. Production Process
The electric scooter hub motor assembly line adopts an automated assembly line operation mode, focusing on four core links: “Component Pre-assembly → Core Assembly → Performance Testing → Finished Product Packaging”. The specific process is as follows:
- Component Loading and Sorting: Through manual + automated loading stations, core components such as stators, rotors, bearings, housings, and connecting wire harnesses are sorted in place to ensure material specification matching.
- Stator Pre-assembly: Automatic bearing press-fitting, winding testing, insulation performance testing to ensure stator electrical performance meets standards.
- Rotor Assembly: Precise fitting of rotor shaft and magnetic steel, dynamic balance testing, removal of eccentric oversized parts.
- Core Assembly: Stator and rotor assembly, housing sealing, automatic bolt tightening with precise torque control.
- Electrical Connection and Commissioning: Connecting wire harness welding, controller matching, power-on testing of motor rotation direction and speed.
- Comprehensive Performance Testing: Waterproof testing, temperature rise testing, load testing, noise testing to verify motor performance in all dimensions.
- Appearance Inspection and Marking: Appearance defect detection, laser marking of product batches and serial numbers to establish a traceability system.
- Finished Product Packaging and Warehousing: Automated bagging, boxing, labeling and transportation to finished product warehouse.
