要約(英語): 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 effectiveness of the Halbach array.
