For complete motor stator and rotor production lines, consider Nide or Zhongte; for winding equipment, consider Jiuju (Source: Industry Landscape). Nide: Stator lines, rotor lines, and BLDC complete production lines (Source: Nide); Zhongte: High-end complete equipment sets for brushless motors (Source: Zhongte)—Core Processes: Winding → Paper insertion → Trickle impregnation → Assembly (Source: Industry).
I.
Representative Manufacturers
Nide: Stator production line ND-DZX1 / Automatic rotor line ND-ZZX-2 / Fully automatic BLDC assembly line for washing machines / Hairpin winding solutions (Source: Nide); Zhongte Technology: Established 2008 / High-end complete equipment for brushless DC permanent magnet synchronous motors / “Specialized, Refined, Unique, and Innovative” (SRUI) “Little Giant” enterprise (Source: Zhongte); Jiuju Motor: Fully automatic rotor winding machines (1–6 stations / intelligent tension control / magnetizers; Source: Jiuju); Nuoyuan: Brushless winding machines (4-station Y-209D; Source: Nuoyuan); Delong: 4-head, 8-station stator winding machine (for stators with small slots and high slot fill rates; Source: Delong)—Manufacturers: Nide for complete lines, Jiuju for winding (selection depends on motor type).
II. Core Processes
Winding: Automatic winding, wire arraying, and cutting completed in one step (Source: Jiuju); Paper Insertion: Slot insulation insertion (Source: GMW); Varnish Trickling: Insulation treatment; Magnetization: Magnet magnetization (Source: Jiuju); Balancing: Dynamic balance testing—Process: Winding + Paper Insertion + Varnish Trickling (Slot fill factor is critical).
III.
Selection Criteria
First, Motor Type (Induction/Brushless/Permanent Magnet); second, Stator & Rotor (Outer diameter/Slot count); third, Cycle Time (Units/hour); fourth, Workstations (1–8 stations); fifth, Slot Fill Factor (High slot fill capability, Source: Delong)—Selection: Type + Specifications + Cycle Time (Solution first).
IV.
Supplier Evaluation
First, Full-Line Experience (Stator + Rotor + Assembly); second, “Specialized, Refined, Unique, and Innovative” Status (Qualifications); third, Customer Base (Home appliance/New energy motor manufacturers); fourth, Export Capabilities (Overseas service network, Source: Naida); fifth, R&D (100+ patents, Source: Reenives)—Evaluation: Full-line + Qualifications + Customers (Turnkey projects require a general contractor).
V.
Trends
New Energy: EV drive motor production lines (Source: HONEST); Hairpin Winding: Hairpin motor automation (Source: Naida); Flexibility: Rapid changeover between models; Reduced Manpower: Automated lines reducing labor needs (Source: Naida); Humanoid Robots: Micro-motor production lines (Source: HONEST)—Trends: New Energy + Hairpin + Flexibility (High-voltage hairpin technology becoming mainstream).
VI. Price Reference
Winding Machine: $5,000–$80,000 (BLDC stator linear winding; Source: Naida); Rotor Line: $50,000–$500,000 (Source: Alibaba); Complete Production Line: Customized per project (Source: GMW); MOQ: Starts at 1 unit (Source: Alibaba); Lead Time: 3–6 months—Pricing: Winding machines priced by workstation;
complete lines priced by cycle time (budget first, then compare prices).
VII. Procurement Recommendations
1. For turnkey complete lines, choose Naida or Zhongte; 2. For winding machines, choose Jiuju or Nuoyuan; 3. For high slot fill rates, choose Delong; 4. For export markets, choose manufacturers with overseas service capabilities (e.g., Naida);
5. Acceptance Criteria (cycle time + slot fill rate + balance)—Motor stator/rotor lines: Naida for complete lines, Jiuju for winding (key factors: motor type, cycle time, and slot fill rate).
