電子齒輪比 & 電子凸輪 傻傻分不清楚!?

1.齒輪：是用於變化原本的速度。

而電子齒輪比，就是用來取代齒輪機構而生的。


2.凸輪：利用主動軸，來帶動凸輪連桿，來對凸輪軸上的零件，產生變化。(順序動作一種)

而電子凸輪，就是利用數位方式來架構凸輪的動作，取代原本的凸輪連桿。

What is the meaning of “Ratio of Load Inertia to Servo Motor Inertia”?

Ratio of load inertia to servo motor inertia: (J_load /J_motor)
J_load: Load inertia J_motor: Motor rotor inertia

When selecting the servo drives and motors that the user want to use, the user not only should consider the motor torque and rated speed, but also need to know the ratio of load inertia to servo motor inertia.

Then, the user can select the proper motor that is correctly matched for the servo drive according to the actual requirements of the connected machine (load condition) operation and the quality and quantity requirements for materials processing and manufacturing.

When perform tuning and trial run, setting (J_load /J_motor) correctly is the most important / essential for optimizing the performance of the mechanical system and servo system and make them work efficiently.

慣性比的意義是什麼?

伺服馬達的負載慣量比：(J_load /J_motor)
J_load為負載慣量
J_motor為馬達轉子慣量
在伺服系統選型時，除考慮馬達的扭矩和額定速度等等因素外，我們還需要先計算得知機械系統換算到馬達軸的慣量，再根據機械的實際動作要求及加工件質量要求來具體選擇具有合適慣量大小的馬達；在調試時,正確設定慣量比參數是充分發揮機械及伺服系統最佳效能的前題。
