本文提出了一种带有 Halbach 阵列的交叉耦合 2 自由度 SPM 电机。在所提出的2-DOF电机中，永磁体（PM）布置在线性方向和旋转方向上，使得电机产生线性方向上的推力和旋转方向上的扭矩。 Halbach阵列应用于直线方向和旋转方向。使用 3-D FEA 分析所提出的电机。分析中对仅直线方向采用Halbach阵列的模型、仅采用旋转方向采用Halbach阵列的模型以及直线方向和旋转方向均采用Halbach阵列的模型进行了比较。分析结果表明，无论是在线性方向还是在旋转方向上，带有Halbach阵列的模型都比没有带Halbach阵列的模型产生更高的力和扭矩。在分析中，除了力和扭矩之外，还分析了磁通量。此外，还进行了实验来确认 Halbach 阵列的有效性。
In this paper, a cross-coupled 2-DOF SPM motor with Halbach array is proposed. In the proposed 2-DOF motor, the permanent magnets (PMs) are arranged in both the linear direction and the rotational direction so that the motor generates thrust force in the linear direction and torque in the rotational direction. The Halbach array is applied to both the linear direction and the rotational direction. The proposed motor is analyzed using 3-D FEA. In the analysis, the model with Halbach array only in the linear direction, the model with Halbach array only in the rotational direction, and the model with Halbach array in both the linear direction and the rotational direction are compared. The analysis results show that the model with Halbach array in both directions generates higher force and torque than not only the model without Halbach array but also the models with Halbach array in either the linear direction or the rotational direction. In the analysis, the magnetic flux is also analyzed in addition to the force and torque. Additionally, experiments are conducted to confirm the e ff ectiveness of the Halbach array.
