Motor Stator Core Stamping Parts

Disc-shaped structure with a central shaft hole and radial slots, serving as the core magnetic circuit component for micro motors or shielded pumps. These parts are stacked to form stator or rotor cores. By constructing a closed magnetic circuit through precision stacking and interlocking tabs, they aim to enhance electromagnetic conversion efficiency and reduce operating noise. They are widely used in home appliances, automotive electronics, and industrial fan drive systems.

The manufacturing process strictly controls the perpendicularity of the sheared section, burr height, and overall flatness after stacking to prevent increased magnetic reluctance or mechanical friction caused by uneven assembly gaps. Addressing the processing characteristics of magnetic materials like silicon steel, the factory utilizes Sodick slow wire EDM equipment to handle micro-features on mold cutting edges. Combined with precision progressive dies for high-speed continuous stamping, this ensures consistency in slot dimensions and material utilization in mass production.

Relying on a quality management system dual-certified by ISO 9001 and IATF 16949, we provide full-process services from drawing evaluation and mold development to finished product delivery. Quotations and lead times are calculated based on specific material grades (e.g., cold-rolled silicon steel, stainless steel), lamination thickness, surface treatment requirements (e.g., insulation coating), and order volume. We support custom manufacturing based on drawings and flexible supply modes for high-mix, low-volume orders.
