本文介绍了在两个轴主动定位的非共位结构的无轴承电机的风力发电应用的低速测试。在风力发电应用中，需要无轴承机器来消除轴承故障。在双轴主动定位无轴承机床中，径向方向被主动定位。通常，倾斜和轴向运动是被动稳定的，因此当施加扰动时有时会发生严重的振动。特别是在非共位结构中，由于径向力的干扰，会发生倾斜振动。本文提出了一种带风扇叶片的圆盘形多极无轴承电机。对四种非共位结构的转子进行了转动试验比较。利用所提出的数学方程计算了稳定磁悬浮所需的积分增益。在低速旋转测试中，对径向和倾斜振动进行评估。
This paper presents low speed test in two-axis actively positioned bearingless machines with non-collocated structure for wind power applications. Bearingless machines have been required in wind power applications to eliminate bearing failures. In the two-axis actively positioned bearingless machine, radial directions are actively positioned. Normally, tilting and axial motions are passively stabilized so that serious vibration sometimes occurs when disturbance is applied. In particular, the tilting vibration occurs in non-collocated structure because of interference with the radial force. In this paper, a disk-shaped multi-pole bearingless machine with a fan blade is presented. Four rotors with non-collocated structure are compared in rotation tests. An appropriate integral gain for stable magnetic suspension is calculated by proposed mathematical equation. In low speed rotation tests, radial and tilting vibrations are evaluated.
