新型高性能各向异性MQA磁粉及其粘结磁体的性能及在电机中的应用

Properties of New High Performance Anisotropic Magnetic MQA Powders and Bonded Magnet and Its Applications in Motors

介绍了一种新型的高性能抗老化各向异性磁粉MQA及其应用，并采用仿真模拟方法对使用该磁粉制备的磁体与传统铁氧体磁体的电机进行了对比分析，结果表明使用该新型磁粉制备的粘结磁体可以显著降低电机的体积、重量和戍本，同时可以得到更高的效率。这种仿真模拟的方法还可以广泛应用于各种新型微特电机的设计中。

This article introduces a new type of anisotropic NdFeB magnetic powders with high magnetic and anti-aging properties. For motor applications, comparisons were made between the motors using new anisotropic bonded Neo magnets and ferrite magnet using virtual prototyping designs by simulation. And the results showed that for motors with the same performance, the size, weight, cost and efficiency can be reduced notably by employing anisotropic bonded Neo magnet from MQA powder, and this virtual design is a good tool for motor designs.
