Large Automatic Stator Winding Machine, 60–250mm Stack Height, Multi-Axis Servo Coil Winding Equipment For Large Three Phase Induction Motor & Pump Motor Mass Production
This large automatic stator winding machine is heavy-duty coil winding equipment dedicated to medium and large-size motor stator manufacturing. Equipped with multi-axis servo linkage and industrial PLC touch screen control, it supports stators with 60–250mm stack height and wider outer diameter range. Built-in constant wire tension control stabilizes enameled wire arrangement and avoids insulation damage. The machine stores dozens of winding programs for fast model conversion, and supports continuous long-cycle operation. It can work independently or connect with paper inserting, coil inserting and lacing machines to construct complete stator production lines, delivering consistent coil density and stable phase resistance for large industrial and pump motor batch manufacturing.

Cause
Traditional winding solutions for large stators mostly depend on semi-automatic equipment and substantial manual assistance. Large-diameter, long-stack stators are difficult to position accurately, easily causing irregular coil stacking and uneven winding tension. Early winding equipment adopts fixed mechanical structure, requiring lengthy mold adjustment when switching stator specifications. Unstable tension control may scratch enamel coating and increase defective coils. Continuous manual intervention extends production cycles and raises labor expenditure. Batch inconsistency of winding turns and coil arrangement brings fluctuation to motor efficiency and operational stability, limiting standardized mass output of large motors.
Solution
Our large automatic stator winding machine adopts reinforced heavy-duty frame and multi-servo closed-loop control to meet large stator processing demands. The high-load positioning fixture firmly locks long and large stators to prevent offset during high-speed winding. Real-time digital tension module maintains uniform wire force for thick copper wire, reducing insulation damage. One-click program switching shortens model replacement time greatly and adapts multi-spec mixed production. Modular wearing parts design simplifies daily maintenance and lowers downtime. Full automatic circulation cuts manual participation, stabilizes winding precision and coil uniformity, effectively improving finished stator qualification rate and lowering comprehensive production expenditure for motor factories.
Application
This equipment serves mass production of large three-phase induction motors, deep well submersible pump motors, fan motors, compressor motors and industrial gear motors. Suitable for medium and large motor manufacturers and professional stator outsourcing processing factories. It seamlessly matches front insulation procedures and subsequent inserting, binding and testing stations, supporting stable daily output of medium and large stators for standardized industrial motor production projects.
How It Works
Operators place the unprocessed stator on the heavy-duty positioning fixture and activate dual-hand safety start. Pneumatic clamping locks the stator core firmly. Servo system loads preset winding parameters and adjusts tension automatically. The winding head performs continuous circular winding according to programmed turns and layers. Constant tension control keeps copper wire neatly arranged. After winding completion, the machine automatically cuts wire and resets. Operators unload finished stator and start the next circulation for continuous batch production.
How to Choose
Confirm stator stack height, outer diameter and copper wire gauge to match machine parameter range. Select this standard heavy-duty model if you produce general large industrial and pump motors. Check workshop bearing capacity and power supply load before installation. Reserve space if later connection with automated conveying lines is required. Verify winding mode requirements to confirm fixture customization demand.
FAQ
Q1: Can molds be customized for non-standard large stators?
A: Yes, we design exclusive fixtures according to customer stator drawings, and support sample winding testing before formal production.
Q2: How long is the equipment lead time after deposit?
A: Standard models deliver within 20 working days; customized mold versions require 28–35 working days.
Q3: What after-sales service can overseas buyers obtain?
A: 12-month whole machine warranty, lifelong remote technical support, cost-price supply of wearing parts and optional overseas installation training.
