70 QC specialists, who utilize 110-plus testing devices, advanced techniques like FMEA and PPAP, administer a battery of tests including material incoming test, 100% inspection on line, packing vibration and outgoing inspection before delivery, all of our motors are RoHs/Reach/CE compliant and the reject rate is no more than 500PPM.

For all the materials and parts we've got from our supplier, we make a battery of inspections like the dimensions, strength, hardness, roughness etc. According to AQL standard to ensure the precision and reliability of the finished products.


  • Roughness Tester

  • Gear Meshing System

  • Measure and record the data of dimensions

  • Measuring the Hardness of Materials

  • Testing the Vibration of Bearings

  • Digital micrometer can be used to measure the components' height, deepness, motor shaft endplay, runout, etc.

The rotor, stator, commutator, back cover and performance are subjected to a series of 100% on-line inspections as well as operator self-test and QC for first inspection and shift inspections. The reject rate does not exceed 3000 PPM (the defective rate of automotive motors is approximately 30 PPM).
