This paper introduces an axial-flux self-bearing motor (ASBM) using two permanent magnet attractive type passive magnetic bearings (PMBs). The ASBM provides both functions of a disc motor and thrust magnetic bearing, and controls motor torque and axial force by single rotational magnetic flux. ThePMB consists of a cylindrical permanent magnet and an iron shaft with conical edge, and it supports the rotor in radial directions. This motor has a simple structure and control system, and it is possible to reduce the size and cost. In this paper, the structure and control method are introduced, and the results of levitation and rotation tests whose non-contact rotation speed was achieved up to 1,500 rpm are shown.

使用两个永磁吸引型无源磁轴承开发轴向磁通自轴承电机

本文介绍了一种使用两个永磁吸引型被动磁轴承(PMB)的轴向磁通自轴承电机(ASBM)。ASBM同时提供碟式电动机和推力磁性轴承的功能,并通过单个旋转磁通量控制电动机扭矩和轴向力。PMB由圆柱形永磁体和带有锥形边缘的铁轴组成,并沿径向方向支撑转子。该电动机具有简单的结构和控制系统,并且可以减小尺寸和成本。介绍了其结构和控制方法,并给出了非接触转速达到1,500 rpm的悬浮和旋转试验的结果。
