Reliable Quality You Can Count On
At Ningbo Zhenhai Yuanyi M&E Manufacture Co., LTD (YME), we follow a strict quality control system covering the entire motor production process. With ISO9001 standards, advanced testing equipment, and a skilled technical team, we make sure that every motor and motor component meets customer requirements and industry expectations.
Quality Management Based on ISO9001
All production processes are executed under the ISO9001 international quality management system. This ensures that quality is monitored, documented, and traceable throughout each stage of manufacturing.
Incoming Component Inspection
Before production begins, we inspect incoming motor components for structural integrity and dimensional accuracy. Tools such as gear gauge centers and roundness measuring instruments are used to ensure part reliability.

Assembly Process Supervision
During motor assembly, skilled workers follow strict procedures, and welding quality, mechanical fitting, and component positioning are closely monitored. Equipment such as hydraulic press machines, welding equipment, and lathe machines ensure accurate assembly.
Performance and Functional Testing
Each motor is thoroughly tested to verify performance before delivery. We use the following key systems:
☆Motor Performance Testing System – Evaluates torque, speed, and efficiency under load.
☆Armature Test System – Checks insulation, continuity, and balance of the armature.
☆Stator Test System – Verifies winding resistance and insulation of the stator.
☆Power Dynamometer – Simulates load to test torque and speed accuracy.
☆Balance Testing Machine – Detects and corrects rotor imbalance to reduce vibration.
These tests ensure that all motors meet required performance, safety, and reliability standards.
Software-Based Test Analysis
We utilize dedicated motor testing software for real-time data analysis and performance validation. This digital approach improves test accuracy and documentation for each unit produced.
Final Quality Inspection Before Delivery
Before packaging, every motor undergoes a final inspection to confirm all specifications have been met. Any defective units are removed from the production line for correction or rejection.
Sample Verification for Custom Orders
For OEM orders or customer-designed motors, we provide sample production and testing. Samples are verified against customer drawings or provided samples to confirm technical specifications before mass production.
Full Production and Shipping Transparency
We keep customers updated throughout the production and delivery process. Information includes production progress, shipping updates, and issue resolution, ensuring timely and transparent communication.
Continuous Feedback and Quality Improvement
Post-delivery, we actively seek customer feedback to track performance and improve future batches. Complaints are handled without delay, and support is personalized for each client.
