Magnets for motors are a high- performance application. One important point is an extreme low air gap between rotor and the magnets in the stator. So, the motor magnets need small tolerance and chamfering. Sometimes, customer order arc shape and make arc magnet together into ring shape, the small tolerance and charmfering affect the ring from arc shape. Specially , if the motor is mini motor, the thickness of arc shoud be small, so the tolerance play import role. Customer and magnet supplier pay more attention on the details.
AOMAG usually supply kinds of magnets for motors, such as brushless motor, DC Motor, AC motor, stepper motor , servo motor, synchronous motor and so on. AOMAG supply Block SmCo, bread and arc Neodymium magnets, Hard ferrite , Multi-polar ring magnet for kinds of motors. Whether mini motor or special motor you manufacture, whether regular shape or irregular shape magnet you need or high temperature magnet or special high â€“ performance Permanent magnet,please contact us to discuss more. we own professional R&D team and advanced production technology to serve customers.
For the high temperaure magnets: we are able to supply, H series, SH series, UH series and SmCo magnets such as S30,S32 (BH)max 250 KJ/m3.
For magnetization direction: such as 8 poles, 14 poles, 32 poles, radial magnetization direction in radial ring magnets.
Most customers require neodymium motor magnets with high maximum working temperature, such as 35SH, 38SH, 35EH, 35UH, use some small arc magnets to form a ring magnet, magnetization direction is through diameter, N-S and S-N. And some require other shapes such as segment, wedge shape, block, ring, or special shape. Sintered neodymium is one of the highest performance permanent magnet material, it is used in many high-tech products, particularly as motor magnets for small and micro-oriented development. Becuase of high remanence, high coercivity and high magnetic energy product, it is widely used, we can supply servo motor magnets, flat brushless motor magnets, and stepper motor magnets etc.
