Single-layer Dense Winding
Enameled wires are closely arranged in the stator tooth slots to form a complete loop, widely used in miniature synchronous motors (such as electric fan oscillating motors and microwave oven turntable motors). It requires accurate turn count and moderate tension to avoid inter-turn short circuits.
Multi-layer Stacked Winding
Multiple layers of coils are wound in layers within a narrow bobbin to enhance magnetic field strength, suitable for scenarios requiring higher torque (such as oven rotating spit motors and air fryer stirring motors). Inter-layer insulation and heat dissipation must be strictly controlled during the process.
Tap-type Winding
An intermediate tap is led out during the winding process to realize different rotating speed or direction switching, commonly used for multi-gear oscillating control of electric fans. The production line must feature automatic tap leading-out function and accurately record the tap position.
Precise Turn Count for Stable Rotating Speed
The rotating speed of a synchronous motor is strictly related to the power supply frequency and coil turn count. Automated production lines deliver precise counting to ensure consistent turn count for every coil, thus minimizing motor speed deviation and stabilizing home appliance functions.
Adapt to Quick Model Changeover for Multiple Specifications
Home appliances feature diverse product models with a wide range of coil dimensions. Yite's production lines adopt modular jigs, enabling quick changeover by replacing bobbins and updating programs in a short time, fully meeting small-batch multi-batch production demands.
Automatic Taping & Coil Shaping
After winding, insulating tape or cable ties are automatically wrapped around the coil, and the coil end is shaped to prevent loosening. This facilitates subsequent coil inserting or assembly, significantly improving production efficiency.
With over 20 years of experience supplying synchronous coil winding equipment to numerous home appliance motor manufacturers, Eternal's production lines cover winding demands from miniature motors to large-sized motors. The equipment supports both round wire and flat wire winding, and its multi-station structure drastically boosts unit output.
We can also integrate online resistance testing and visual appearance inspection to automatically reject defective products. The after-sales team provides on-site installation, commissioning and operation training, with timely nationwide technical support.
