摘要:
建立了纵扭复合型压电超声电机输出扭矩的数学模型.根据模型讨论了预压力Fpre、纵振激振电压VL、扭振激振电压Vt、摩擦力f、电机的输出扭矩Mout、转子转速ωR和扭振子振动速度ωV等的关系.在实验中发现:电机的最大输出扭矩并不总是随扭振激振电压Vt的增大而增大,当扭振子输入电压达到300 V以后,电机的最大输出扭矩不再增加,而是有一最大值,当扭振子输入电压达到350 V时,电机的最大输出扭矩达1 N·m.可用上述模型解释这种现象.模型的仿真结果和实验结果相对吻合.
Abstract:
A torque output mathematics model of ultrasonic motor using longitudinal and torsional mode is presented. The relation of pre-pressure, excitation volt for longitudinal vibration,excitation volt for torsional vibration, friction force, torque output, speed of rotor, and vibration speed of torsional vibrator is discussed. The experiments show that the maximum torque output stops increasing and gets a maximum value when the excitation volt for torsional vibration reaches 300 V. The motor’s maximum torque output is 1 N·m when Vt is 350 V.This phenomenon can be explained by the presented model. The simulation results and experiment results are coincident.
