本文介绍了螺旋运动电机的高性能位置和力控制。该电机是一种轴向气隙表面永磁同步电机，定子和转子均为螺旋形。由于这种形状，这种直接驱动电机可以在不使用任何机械传动系统的情况下产生高推力。实验结果表明，该电机尺寸为φ55×132 mm，推力可达200N。推力密度为0.64MN/m~3，力质比为133N/kg，是常规直线电机的两倍或两倍以上。
This paper reports high-performance position and force control of helical motion motors. This motor is an axial-gap surface permanent magnet (SPM) synchronous motor having helical stator and rotor. Thanks to this shape, this direct-drive motor can generate high thrust force without using any mechanical transmission system. The experimental results show that thrust force of 200N is achieved by the proposed motor of φ55×132mm size. The thrust-force density is 0.64MN/m3and force-to-mass ratio is 133N/kg which is two or more times higher than the conventional linear motors.
