有大大知道類比和數位伺服器的差異嗎?

除了價格
以外呢?

它們的原裡是差在哪呢>?

就我所知道

普通類比的伺服機 有訊號的回受 來決定伺服機的角度
如果沒記錯 就是VR的訊號送回伺服機內部的晶片已決定角度是否到了定點
因為這個訊號的回受 很可能會送回接收機 會干擾其他的伺服機

如果是數位式的 接收機送給伺服機的訊號本來就是數位的
伺服機本身根據這個訊號來決定角度 沒有訊號的回受
因此不會干擾其他的伺服機

king

那是不是如果接收器不是數位的
就不可以用數位的伺服器呢?

換句話說
如果接收是數位的
伺服器也不可以用類比的呢?

接收機沒有差別
他送給伺服機的訊號本來就是數位的
如果是類比的伺服機 內部晶片會將數位訊號轉換的

pico

伺服器的接線還是一樣的
至於說兩種不同的是怎麼運作 是在伺服機內部處理的工作
跟外面是什麼 沒有很大的差別
而用在陀螺後面的 尾伺服機 因為他有很頻繁的左右修正細微動作
陀螺送給伺服機的訊號 可以因為他是數位的伺服機
而有不同的訊號模式 可以突顯數位伺服機的長處 而有更好的表現

然而 這種專門用來驅動數位伺服器的訊號
確有可能會是類比伺服器沒辦法正確解讀的
或是因為超過他驅動的能力 而使得類比伺服器因此而減短壽命

那gy401 DS模式

那為什麼類比伺服器會燒掉呢

這裡是詳細的說明
抱歉 我在之前所做的比較 不全然正確

Many people think that Digitals are stronger and faster than analogue, but speed and power as mentioned is dependant upon the motor and gearing used in the servo (just like any servo).

The increase is due to the way that digitals work. In simple terms, both digis and analogue use a feedback loop to get the servo arm to move to the desired position. The difference is that with digis it is either on or off, so 100% of the force is applied as soon as a difference is noticed, while with an analogue, it builds up as the difference increases.

This gives the digi the holding power and centering that it is known for. It is what also causes the hum that digis are also known for, the weight of the control surface will cause the servo arm to deflect ever so slightly, the servo picks this up deflection, and corrects it with 100% of power.

In an analogue, it will find a happy medium where the force of the deflected contol surface counteracts the correcting force being applied by the servo.

Personally I do think that digis will become far more widespread over the next couple of years, but will not replace the analog servos completely for some years after that.

很多人都認為數位式的會比類比式的強 比較快 但是 講到速度 還有力量還是要取決於他使用的馬達 還有齒輪(任何一顆伺服器也都是這樣)

多出來的就是他使用數位式的工作原理. 簡單的來說 數位或是類比 都使用回受訊號 以如願的將伺服器擺臂移動到預期的位置. 不一樣的是數位伺服器的訊號不是1就是0 所以是用全部的力量去轉動, 類比的伺服器卻是利用輸入訊號跟回受訊號比較的差異而有所不同的驅動速度

This gives the digi the holding power and centering that it is known for. It is what also causes the hum that digis are also known for, the weight of the control surface will cause the servo arm to deflect ever so slightly, the servo picks this up deflection, and corrects it with 100% of power.
這就是為什麼他的他可以有很好的拉力 和中力點特性由來, 這也就是他的哈姆聲的由來. 他的控制介面的優勢 將會使得伺服器輕易的就能轉動就擺臂,伺服器靠這樣轉動而且用全功率來修正

In an analogue, it will find a happy medium where the force of the deflected contol surface counteracts the correcting force being applied by the servo.

越看越迷糊

這樣的話
跟訊號好像又沒關係耶

一頭霧水

大家來接力

數位伺服機的出力比類比大是因為數位的訊號不是OFF 就是ON 當角度不對時100啪的力量會用來修正

可是類比的是當差越大時 力量才隨著增加


This gives the digi the holding power and centering that it is known for. It is what also causes the hum that digis are also known for, the weight of the control surface will cause the servo arm to deflect ever so slightly, the servo picks this up deflection, and corrects it with 100% of power.
這使得數位的有足夠力量維持需求角度的中心點

In an analogue, it will find a happy medium where the force of the deflected contol surface counteracts the correcting force being applied by the servo.
在類比的 適當的出力與阻力平衡時 臏u回到中心點


Personally I do think that digis will become far more widespread over the next couple of years, but will not replace the analog servos completely for some years after that.
他認為數位的會取代類比的


翻的有點粗略
