摘要:
 摘要:针对传统电机机械轴承所带来的摩擦损耗问题,提出一种新型液质悬浮式的三自由度电机,该电机引入液质流体可实现悬浮运动。详细阐述了该新型电机的工作原理及电磁特性,采用三维有限元软件对电机进行建模仿真,给出在平行充磁条件下单个磁极的磁通密度的三维曲面分布图,并从解析角度建立了电机磁密的数学方程,进而结合电机结构及磁通管原理,建立了球坐标系下的三维磁网络模型,获取了气隙磁场的磁密值与转矩值,得到了转矩在不同位置角下的变化情况,分析得到电机的输出性能。最后对样机进行测试并将实验结果与上述两类方法进行对比,验证了等效磁网络法建模的合理性。
Abstract:
According to the bearings, licquid suspension type three-degree-of-freedom motor is presented,which can complete frictionless move­ ment by introducing liquid fluid into the motor.The working principle and electromagnetic friction loss Problems caused by the traditional mechanical characteristics of this new type motor are described in detail.By using 3Dfinite element software for the motors modeling and simulation,the 3D surface distribution profiles of single-pole magnetic flux density under the condi­tion of parallel magnetization are given,and the mathematical equations of the motor0 magnetic flux den­sity from an analytical point of view is establislied.Then,combined with the motor structure and the mag­ netic flux tube principle,the 3Dmagnetic network model is built in the spherical coordinate,and t density and torque values of the air gap magnetic field are derived.The change of torque at different posi­tion angles is also obtained,and the output performance of t!ie motor is analyzed and derived.Finally,the test is conducted on the prototype and the experimental results are compared with the above two methods, which verifies the rationality of the equivalent magnetic network modeling.
