Factory Spotlight: Coil Winding in Action at Hechao Motor 

WENLING, Zhejiang – At the heart of electric motor production lies the critical process of coil winding, and Zhejiang Hechao Motor Co., Ltd. is demonstrating the high standards and craftsmanship behind their operations.

The video captures the real‑time workflow of motor winding. Key phases in the operation include:

Pre‑treatment: cleaning of stator slots, measuring wire diameter, and cutting insulating paper.

Coil fabrication: using continuous winding to form phase coils, inserting insulating sleeves to maintain inter‑layer separation.

Winding insertion: embedding the coils into the slots according to the “insert two slots, leave two slots” rule, alternating downward­press insertion and side‑edge sealing of the dangling leads.

Terminal finishing: welding star‑connection circuits, securing with cable‑ties and fixing the output terminals.

By standardizing the process flow and integrating automated equipment where appropriate, the company ensures uniform quality and manufacturing efficiency — aligning with the broader motor‑winding industry’s trend toward greater automation and tighter tolerances.
