Because Neodymium magnet has a wide range of magnetic properties, it can be used in many types and purposes of electric motors. H grades or even M grades are used in stepper motors; SH grades are used in servo motors; UH or EH grades are used in EV motors. Laminated Neodymium magnets with high Hcj are used in new energy motors, aerospace, etc. For the electric motor application, we focus on research and production of high end series of Neodymium magnets, which are mainly used in servo motors, traction motors, linear motors and elevator motors, etc.
A "motor magnet" can encompass various types of magnets, including neodymium (NdFeB), ferrite, samarium cobalt (SmCo), and alnico magnets, depending on the specific requirements of the motor design and application.
Among these options, neodymium magnets are commonly favored for their exceptional magnetic strength-to-size ratio, which allows for the creation of compact and efficient motors. These magnets are often used in applications where space and weight are critical factors, such as in electric vehicles, industrial machinery, computer hard drives, and power tools.
Magnets for Motor Applications

Motor magnets play a crucial role in generating the magnetic fields necessary for motor operation. They are typically positioned within the motor's rotor or stator assembly, where they interact with electrical currents to produce rotational motion. The choice of magnet material and configuration depends on factors such as operating temperature, magnetic strength, cost, and environmental considerations. We have many years of experience in manufacturing motor magnets and specialize in providing customers with the right type of magnet.
