有大大知道類比和數位伺服器的差異嗎?

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).
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 還有齒輪齒比數(任何一顆伺服器也都是這樣)

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.
增加的速度與力量就是因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.
這就是為什麼數位式可以有很好的拉力 和中力點特性由來.　機身上的控制介面重量會使控制介面稍微下垂, 數位式伺服器感覺到此下垂而使用100%的功率來修正.　這也就是他的哈姆聲的由來.

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.
伺服器會在控制介面所產生的力量與伺服器本身的出力之間找到一個綜合點.

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.
我個人認為數位式將在未來幾年更為普遍.　但在近幾年內不會完全取代analog伺服機.
