Key Appliance and our Advantages:
      1. Permanent Servo Motor
NdFeB magnet is highly praised for its superiority in magnetic performance. SATT offers customized service to design and produce NdFeB magnet with high performance, consistence and temperature resistance to fit diversely customer requirements in the servo motor field.
      2. Magnets for Elevator TractorThe safety and stability of elevator is influenced by the performance of NdFeB magnets. We always stand on our ideology, Quality first, safety first and people-oriented, to assure quality and performance of our goods.
      3. Magnets for Variable Frequency CompressorThe NdFeB magnets we offered has advantageous performance, including low temperature coefficient, irreversible demagnetization rate on high temperature, high corrosion resistance under high temperature environment fill with Freon and refrigerant oil. Besides, it could improve the efficiency and stability of air conditioner compressor.
     4. Radial Multi-poles ring magnetThe radial multi-poles ring magnet developed by SATT has completely innovative design which reaches higher surface magnetic flux density and overmatched the traditional approach of piece several segment magnets together. Our product has a sinusoidal wave shaped surface magnetic field distribution, is relatively better for motor design than saddle-shape of radiation ring.
