NdFeB Coreless Servo Motor Ring Magnets, Magnetic Tube in Space Probe


  1. Coreless Motor Ring Magnet Superiority: Sintered NdFeB permanent magnets, known for their high remanence, high coercivity, and high energy products, are the optimal choice for coreless motors. Their properties align perfectly with the demands of coreless motor applications.
  2. Market-Leading Magnet Material: As the most suitable permanent magnet material available, sintered NdFeB magnets are the gold standard for coreless motors. They outperform other materials in meeting the specific needs of these motors.
  3. Magnet Strength and Motor Speed: The strength of the magnets used in coreless motors directly impacts the motor’s speed. Therefore, selecting the right magnet is crucial for achieving the desired motor performance.
  4. Common Neodymium Magnet Profiles: Ring-shaped neodymium magnets, such as N45SH and N48SH grades, are commonly used in coreless motors due to their excellent performance characteristics and temperature resistance of approximately 150°C.
  5. Micro ring magnets: the minimum diameter of the coreless motor magnetic ring is 2.5mm and the maximum is 50mm, the minimum height is 1.5mm, and the maximum height is 50mm.
