【摘要】：磁懸浮平面電機是多自由度機電驅動器中的一種，它在xy平面上運動，相當于多個直線電機復合疊加后的效果，磁懸浮平面電機最大的優(yōu)點是定子和動子之間不需要電纜連接，而是由磁鐵陣列下面通電的線圈陣列，給動子提供水平和垂直方向的驅動力。 本文設計方案為動磁鋼式人字形（HPPA）磁懸浮平面電機，文中完成了磁鐵和線圈等相關材料的選型，給出了磁懸浮平面電機的詳細設計步驟，本文這種方案成功避免了當線圈陣列通入電流時，受電磁力的作用而相互運動的影響，在此基礎之上給出了磁懸浮平面電機的詳細設計圖紙，并由solidworks軟件給出了它的三維效果圖。 其次，對于動磁鋼式二維Halbach陣列，本文給出了其理論推導過程，并利用電磁學分析軟件ANSYS/Emag模塊對該設計方案的單邊性和正弦性等相關特性加以驗證，這為接下來的磁懸浮平面電機的理論分析奠定了基礎。 接下來，本文給出了當單個線圈通電后受電磁力的理論推導過程，，在對磁懸浮平面電機特性進行合理的假設基礎之上，基于模式力的概念建立了磁懸浮平面電機動力學模型，并給出了其解耦動力學方程。 在本文最后一章，首先介紹了歐拉角的概念，在結合磁懸浮平面電機質量，轉動慣量等相關特性情況下，以及考慮不確定因素k k1k情形下，在此基礎上列寫出了單自由度動力學狀態(tài)方程。在多自由度運動中，首先設定了6個狀態(tài)變量，接下來對電磁力進行線性化，最終給出了基于小信號模型的狀態(tài)空間方程。
[Abstract]:The maglev plane motor is one of the electromechanical actuators with multiple degrees of freedom. It moves on the XY plane and is equivalent to the effect of multiple linear motors after composite superposition. The biggest advantage of the magnetic levitation plane motor is that no cable connection is required between the stator and the actuator. Instead, the coil array, which is electrified under the magnet array, provides horizontal and vertical driving force for the actuator. In this paper, the magnetic levitation plane motor is designed in the form of a moving magnetic steel herringbone (HPPA). The selection of magnets and coils and other related materials is completed in this paper. The detailed design steps of the magnetic levitation plane motor are given. This scheme successfully avoids the influence of the electromagnetic force on each other when the coil array enters the current. On this basis, the detailed design drawings of the magnetic levitation plane motor are given, and the three-dimensional effect diagram of the magnetic levitation plane motor is given by solidworks software. Secondly, the theoretical derivation process of the dynamic magnetic steel two-dimensional Halbach array is given in this paper. The electromagnetic analysis software ANSYS- Emag module is used to verify the one-sided and sinusoidal characteristics of the design, which lays a foundation for the theoretical analysis of the maglev plane motor. In this paper, the theoretical derivation process of electromagnetic force is given when a single coil is electrified. Based on the reasonable assumption of the characteristics of the magnetic levitation plane motor, the dynamic model of the magnetic levitation plane motor is established based on the concept of mode force. In the last chapter of this paper, the concept of Euler angle is introduced, which is based on the mass and moment of inertia of the maglev plane motor, and the uncertain factor k k 1k is considered. On this basis, the dynamic state equation of single degree of freedom is presented. In the motion of multiple degrees of freedom, six state variables are first set, then the electromagnetic force is linearized, and finally the state space equation based on the small signal model is given.
