Since 1990 NdFeB Permanent Magnet has slowly replaced ferrite magnet and begin to play an important role in Motor industry. Nowadays, NdFeB Magnets including sintered NdFeB and Bonded NdFeB are widely used on different motors and generators.

Direct current Motors have high requirement on Hcj. So choosing the grade, such as N35H, N35SH, and N35UH, is very important thing. It refers to magnetic strength, temperature endurance, reversibility temperature.

When you contact us for motor magnet, please supply more details on concrete parameter such as Hcb or Hcj, usage direction (for rotor or stator) to improve the success rate of sample, except magnet information (size, coating, grade, magnetization direction, quantity) 

China Magnets Source Material Limited concentrates on research and development Permanent Magnet for Direct Current Motor. Relying on Professional craftsmanship and rich production experience, CMS Magnets is able to meet your special requirement and manufacture kinds of irregular shape for direct motors.

PS: you also can choose other material for motor magnet, such as ferrite, smco, alnico based on your design.
