In order to meet the needs of compactness and high efficiency, many (Nd-Fe-B) NdFe-B NdFeB Magnets are used in electric power steering structures. It can handle general cuboid and shingle shapes, and can also handle radial radial anisotropic ring magnets. In the case of radial anisotropic ring magnets, the degree of freedom in setting the number of stages is high, the assembly work is easier, and it can be further tilted relative to the axis of rotation for magnetization (oblique magnetization), which can reduce the cogging torque (rotation pulsation). In addition, it contributes to the efficiency of various electrification applications (EGR, etc.).
use
1. Spindle motor (HDD, FDD use, etc.)
2. Servo motors (robots, mechanical equipment, etc.)
3. Various auxiliary motors for automobiles (steering wheel electric assist applications, etc.)
4. All kinds of transmission actuators
peculiarity
1. Cylindrical shape, high dimensional accuracy.
2. As a rotor, the magnetic beam density distribution is uniform.
3. It is easy to fix the magnet and can reduce the assembly cost.
4. The rotor is composed of a single magnet and has high reliability.
5. The number of magnetic poles and oblique magnetization can be arbitrarily determined. (Radiation ring)
6. Surface magnetic beam density distribution of sine wave can be provided. (multistage ring)
