Stator Core Quality Inspection Throughout Every Manufacturing Stage
Comprehensive quality inspection throughout every manufacturing stage ensures accurate dimensions, controlled processes, reliable core performance, and consistent product quality.
Quality is integrated into every stage of manufacturing—from raw material verification to final inspection. Our inspection system is designed to ensure dimensional accuracy, stable magnetic performance, and consistent production quality for every motor core we deliver.
Our Quality Philosophy
Qulity Inspection View
Key Inspection Items
Raw Material Inspection
Verify electrical steel grade, thickness, coating, and surface condition before production
Measure OD, ID, slot geometry, and critical dimensions according to customer drawings
Dimensional Inspection
Burr Inspection
Control burr height to protect insulation and improve motor reliability

Frequently Asked Questions
How do you inspect stator cores?
We inspect stator cores throughout the manufacturing process, including material, dimensions, burr height, flatness, concentricity, stack height, appearance, welding or bonding quality, and core loss. Critical results are recorded and compared with customer drawings and agreed specifications.
Which dimensions are inspected?
We offer a [brief explanation of how your product or service helps your customers]. Our process is [simple/efficient/convenient] and [positive adjective] for you.
How is burr height controlled?
Burr height is controlled through precision tooling, optimized punch-to-die clearance, controlled stamping parameters, and regular in-process inspection. We measure burr height during production and adjust tooling or process conditions when necessary to maintain consistent quality.
Can inspection reports be provided?
Yes. We can provide inspection reports and quality records according to customer requirements, including dimensional inspection, burr height, flatness, concentricity, stack height, appearance, and other agreed inspection results. Reports can support quality verification and product traceability.
Do you perform 100% inspection?
Yes, 100% inspection can be provided for critical dimensions or specific quality requirements when required by the customer. The inspection scope can be agreed based on the core design, production volume, tolerance requirements, and quality standards.
