Motor Stator Core Stamping Parts

We provide high-precision stator and rotor core stamping assemblies, serving as the core power transmission components for micro-motors, shielded pumps, and power tools. These disc-shaped structures are positioned via a central shaft hole, with uniformly distributed扇形 slots around the periphery for winding coils or mounting magnetic poles. The coaxiality between the inner hole and outer circle directly determines the dynamic balance performance and electromagnetic efficiency during motor operation, making these parts critical for ensuring low-noise, high-efficiency equipment performance.

Our manufacturing process strictly controls the perpendicularity of the sheared cross-section, burr height, and overall flatness after lamination to prevent increased magnetic resistance or mechanical friction caused by uneven assembly gaps. Leveraging the machining characteristics of magnetic materials like silicon steel, we utilize Sodick slow-feed wire-cutting equipment to process micro-features on mold edges. Combined with precision progressive dies for high-speed continuous stamping, this approach effectively ensures consistency in slot dimensions and material utilization across mass production, meeting the stringent tolerance requirements of the IATF16949 system for automotive parts and precision electronic accessories.

Supported by a quality management system dual-certified under ISO 9001 and IATF16949, our production services cover the entire workflow from drawing evaluation and mold development to final delivery. Quotations and lead times are calculated based on specific material grades (such as cold-rolled silicon steel or stainless steel), lamination thickness, surface treatment requirements (e.g., insulation coating), and order volume. We support custom manufacturing based on customer drawings and offer flexible supply modes for multi-variety, small-batch orders.
