本文提出了一种新型中点电流注入式无轴承永磁同步电机定子主绕组结构。与传统的无轴承电机在同一定子中同时包含主电机绕组和径向力控制绕组不同，这种特殊电机只有电机定子绕组，没有径向力定子绕组。电机定子绕组中只需要中点端子即可注入电流。简要介绍了其工作原理及其特殊结构。所提出的无轴承电机的有效性是相对于传统的无轴承电机而言的。还介绍了强调振动抑制的实验室原型机的测试结果。
In this paper, a novel stator main winding structure of a middle-point-current-injection-type bearingless permanent-magnet synchronous motor is proposed. Unlike the conventional bearingless motor consisting of both main motor windings and radial force control windings in the same stator, this special motor has only motor stator windings and no radial force stator windings. Only middle-point terminals are needed in the motor stator windings to inject currents. The principle of operation and its special structures are briefly described. The effectiveness of the proposed bearingless motor is presented with respect to conventional bearingless motors. Test results of a laboratory prototype machine highlighting vibration suppression are also presented.
