| 摘 要： | 近年,直线电机因结构简单而获得了广泛应用。为了研究其频率特性,该文介绍了一种小型空压机驱动用永磁直线振荡电机。电机采用特殊结构的盘式弹簧轴承,使电机谐振频率的设计与调整灵活方便。文中讨论了驱动电源特性与电机固有谐振频率的匹配问题,研制了电流反馈式谐振频率跟踪驱动器,使电源效率自动跟踪机电系统的谐振频率,并进行了实验调试,效果较好。

| Abstract: | The paper presents a type of linear PM oscillate motor which is used for air compressor.A disc-shaped spring bearing with special constructer is designed which makes the resonant frequency of the motor adjustable.The paper also discusses the relationship between output frequency of driver and the resonant frequency of motor,the resonant frequency tracked driver with current feedback is constructed for experiment. |
