The TH-900M Rotor Surface Magnetic Distribution Tester is a manually positioned multipolar surface magnetization quality inspection system. This system can quickly and efficiently test the surface magnetic field distribution of products such as multipolar magnetized rings and multipolar motor rotors and analyze them using proprietary algorithms to achieve quality control objectives. 

The TH-900M is an efficient, cost-effective surface magnetic field distribution testing device, easy to use and maintain. The rotating shaft is equipped with a 1:10 reducer paired with a servo motor, providing high circumferential testing accuracy, stable operation, and noiseless performance.
