伺服馬達動態量測分析

本論文的目的是建立一套伺服馬達驅動動態特性量測平台，以煞車器為負載，並於伺服馬達與煞車器間串接非接觸式動力計，量測伺服馬達產生速度振盪時的扭矩，並以B&Ｋ的加速規、噪音計，配合馬達驅動軟體ASDA Soft與B&K的PULSE LabShop分析軟體，取得馬達啟動的轉速、振動與噪音的實測數據，以了解馬達的驅動特性。論文中，藉由規劃伺服馬達的轉速以及加速時間，取得在各種加速度下平台的振動值，找出馬達加速度過大時，轉速曲線所產生振盪的瞬間現象。此論文主要分別以振動、扭矩、噪音三個項目為量測方向，比對相互之間的關係。以馬達的各種加速度改變，整理並找出振盪產生的臨界加速度，希望能藉以有效避免暫態速度的產生。而利用實驗中各項數據的互相關聯，我們能判斷出馬達在運作時的各種影響以及預測其趨勢，進而依照工程需求的狀況，去規劃馬達的工作行程。

The purpose of this paper is to measure the angular velocity and vibration of the servo motor by the experimental platform with spectrum analysis instrument. By using ASDA Soft analysis software and PULSE LabShop analysis software, the instantaneous angular velocity, vibration, torque and noise of the servo motor can be obtained. Within the different angular velocity of servo motor, we can observe the vibration value of the platform of the over shut in the critical angular accelerations. This paper use vibration meter, torque sensor and sound level meter to find the relationship and verify the reliability of the vibration, torque and noise. So we can identify the over shut of the angular velocity when the accelerations of motor are too large. Then we can obtain the critical angular velocity of over shut in this way. To make use of the experimental data to relate to each others, we can not only determine the critical operation and predict trends of the servo motor, but planning the work of the motor in our needed.
