Mathematical Modeling and Analysis of Magnetoresistive Magnetic Levitation Spherical Joint
摘要: 为了解决磁阻式磁悬浮球形关节转子转动过程的稳定支承问题，提出一种新型的16齿极转子结构和线圈驱动机制，确保在自旋或偏转过程中转子齿极始终受到两对正交磁悬浮力，为转子提供稳定支承。首先根据电磁作用机制建立定转子之间四个磁悬浮力的力平衡支承模型。然后使用Ansoft有限元软件进行了各种工况和参数下的三维磁场的实验分析，验证了磁阻式磁悬浮球形关节转子的矩角特性和支力–偏角关系，为磁阻式磁悬浮球形关节的稳定悬浮和驱动提供保证。
Abstract: In order to solve the problem of stable support during the rotation of the reluctance magnetic suspension spherical joint rotor, a new type of 16-tooth rotor structure and coil drive mechanism is proposed to ensure that the rotor teeth are always subjected to two pairs of orthogonal during spinning or deflection. The magnetic levitation force provides stable support for the rotor. First, the force balance support model of the four magnetic levitation forces between the stator and the rotor is established according to the electromagnetic action mechanism. Then, we use Ansoft finite element software to carry out the experimental analysis of the three-dimensional magnetic field under various working conditions and parameters, and verify the moment angle characteristics and the supporting force-deflection angle relationship of the reluctance magnetic suspension spherical joint rotor, providing guarantee for the stable suspension and drive.
