Automatic Coordinate Measuring Machine（CMM）is essential precision control equipment in the production of complete motors, motor components, and motor molds, and are indispensable in virtually all mid- to high-end motor manufacturers (including servo motors, new energy motors, permanent magnet motors, and micro motors).

Measuring the accuracy of a motor

Ensures that the stator is pressed into place without eccentricity, resulting in a uniform motor air gap and reduced vibration and noise. Ensures bearing assembly accuracy, controls motor radial runout, and extends service life. Ensures a uniform air gap between the stator and rotor, reducing electromagnetic noise and abnormal temperature rise. Serves as a dimensional reference prior to rotor dynamic balancing, ensuring stable high-speed operation. Used to ensure batch consistency and comply with quality management systems such as IATF 16949.
