【摘要】 从实现圆柱-球体多自由度超声电机的运动原理和提高其输出性能的角度出发,提出了该种电机设计的基本要求。在此基础上,设计了一种新的电机定子结构,并用有限元法对该定子进行了模态分析和设计计算。依据设计结果,制作了样机。实验结果表明,定子的工作模态基本上满足其设计要求,电机的输出性能较以前有了大幅度的提高。同时也证明所采用的设计方法是正确的。更多还原

【Abstract】 In order to realize three-DOF motion and improve operating properties of the cylinder-sphere ultrasonic motor with three-DOF,some design criterion for the motor are outlined.A new type construction of stator is suggested.Modal analysis and the constructional design on the stator are completed with Finite Element Method(FEM).The stator used for a prototype motor is manufactured with FEM results.The experiments indicate that the modes of the stator satisfy the motor operational requirements,and the motor output properties are improved greatly.更多还原
