Product Description
The 2 Winding Heads Electrical Motor Automatic Stator Winding Machine is a dual-head automatic winding solution specifically engineered for washing machine motor manufacturing and other high-volume stator production applications. Featuring two independent winding heads that operate simultaneously, this machine dramatically doubles production output compared to single-head alternatives. The machine adopts a double-station turntable structure with servo-driven indexing transfer, supporting wire diameters from 0.18mm to 1.2mm and accommodating stator outer diameters up to 200mm. With PLC control and HMI touchscreen interface, the machine enables fully automatic winding with programmable parameters including turn count, winding speed, and multi-layer arrangements. Designed for washing machine motors, compressor motors, fan motors, and pump motors, this dual-head winding machine significantly reduces labor dependency while delivering consistent, high-quality windings

Cause
Washing machine motor stator winding has long been a production bottleneck in the appliance manufacturing industry. Traditional single-head winding machines require stators to be wound one at a time, limiting throughput and creating production bottlenecks in high-volume environments. With the rising global demand for washing machines—particularly inverter and BLDC models—manufacturers face mounting pressure to increase production capacity while maintaining consistent quality.
Manual intervention in the winding process introduces multiple quality issues. Variations in wire tension lead to inconsistent coil resistance and motor performance. Improper wire layering causes coil crossing and disorder, resulting in wire damage and enamel breakage. The transition from one stator to another in single-head machines involves frequent loading and unloading cycles, increasing operator fatigue and reducing overall efficiency. As labor costs continue rising and skilled technicians become increasingly scarce, manufacturers urgently need automation solutions that can double throughput without compromising quality.
Solution
Our 2 Winding Heads Electrical Motor Automatic Stator Winding Machine delivers a comprehensive solution that directly addresses the throughput and quality challenges of washing machine motor production. The dual-head design enables two stators to be wound simultaneously, effectively doubling production output in the same footprint as single-head machines.
The machine features a double-station turntable structure with servo-driven indexing transfer. Each winding head operates independently under PLC control, with the ability to wind the main phase and auxiliary phase coils simultaneously. The HMI touchscreen allows operators to store multiple winding recipes, facilitating quick changeovers between different motor models with different slot counts, pole configurations, and winding patterns.
Advanced features include automatic wire clamping and cutting, automatic indexing, automatic skipping, and adjustable winding tension. The coil winding data is displayed in real-time on the touchscreen, and the machine automatically stops when the copper wire runs out, preventing scrap and protecting the workpiece.
The machine supports continuous and discontinuous winding methods, accommodating 2-pole, 4-pole, and 6-pole coil configurations. With a winding speed of up to 2500 RPM, the machine delivers exceptional productivity while maintaining a first-pass yield exceeding 98.5%.
Application
This dual-head automatic stator winding machine is ideally suited for high-volume motor manufacturing, particularly for washing machine motors including both conventional and inverter BLDC types. Primary applications include washing machine motor stators for both drum and turbo washing machines; compressor motors for refrigeration systems; fan motors for HVAC and cooling applications; pump motors for water circulation and industrial use; air conditioner motors; and generator stators. The machine also accommodates BLDC and brushless DC motor stators with special-shaped slots.
How It Works
The dual-head automatic stator winding machine operates through an integrated sequence controlled by PLC programming. Step 1: The operator loads stators onto the two working stations of the turntable. Step 2: Through the HMI touchscreen, the operator selects the appropriate winding program, which stores parameters including turn number, winding speed, tooling sunk height, and winding direction.
Step 3: The turntable indexes to position the stators under the two winding heads. Step 4: The servo-driven winding heads begin winding simultaneously, with each head independently controlled to accommodate different winding patterns if required. The main phase and auxiliary phase can be wound simultaneously. Step 5: During winding, the machine automatically arranges coils neatly into the transfer cups, effectively avoiding wire breakage and damage caused by coil crossing and disorder.
Step 6: Upon completion of the winding cycle, the machine performs automatic wire clamping and cutting. Step 7: The turntable indexes to the next position, and the operator unloads finished stators while loading new ones. Throughout the process, the PLC continuously monitors tension and detects wire breaks, automatically stopping the machine if abnormalities are detected.
How to Choose
Production Volume Requirements: For high-volume washing machine motor production, the dual-head design is essential. Calculate your required daily output—a dual-head machine can effectively double the throughput of a single-head machine in the same timeframe.
Stator Size Compatibility: Verify that your stator‘s outer diameter (≤160–200mm) and stack height (≤100–160mm) fall within the machine’s operating range. For larger stators beyond these limits, custom configurations may be available.
Winding Complexity: Assess whether your application requires simultaneous main phase and auxiliary phase winding. The dual-head design supports this capability, reducing cycle time for motors with multiple winding phases.
Changeover Frequency: For manufacturers producing multiple motor models, the HMI‘s recipe storage capability and quick tooling changeover (approximately 15 minutes for a complete tooling set) are critical for minimizing downtime.
Wire Type and Diameter: The machine accommodates both copper and aluminum wires from 0.18mm to 1.2mm. Consider your wire diameter range—finer wires may require slower winding speeds to prevent breakage, while thicker wires may need higher tension settings.
FAQ
Q1: How does the dual-head design improve production efficiency compared to single-head machines?
A: The dual-head design enables two stators to be wound simultaneously, effectively doubling production output in the same timeframe as a single-head machine. This is particularly valuable for high-volume washing machine motor production where throughput is critical.
Q2: What is the typical winding speed of this machine?
A: The machine achieves maximum winding speeds of 1800–2500 RPM depending on the specific model and configuration. Actual speed may vary based on wire diameter, stator geometry, and winding complexity.
Q3: Can this machine handle both conventional and inverter washing machine motors?
A: Yes. The machine is suitable for both conventional AC motor stators and inverter BLDC motor stators. The programmable control system allows storage of different winding patterns for various motor types.
Q4: Does the machine support automatic wire break detection?
A: Yes. The machine features automatic wire break detection and will stop immediately when abnormalities are detected. This prevents scrap and protects the workpiece from damage.
Q5: How long does it take to change over between different stator models?
A: Complete tooling changeover takes approximately 15 minutes. The HMI touchscreen stores parameters for different stator models, allowing rapid recall and reducing setup time.
