Digital servo motors offer two advantages over conventional analog servo motors namely speed and holding power. The microprocessor that controls a digital servo motors position is six times faster than the analog one. Digital servo motors offer higher resolution that reduces dead band and thereby provides ultimate control. Digital servo motors also produce constant torque and have considerably more holding power. One disadvantage (who cares) of digital servo motors is that they consume more battery power, so when used in a rc nitro car one must use a high capacity NiMH pack.作者: Simon 時間: 2011-6-4 17:03
There are some other important parameter that must be known: I would call it position tracking latency, meaning that how much time is required for the servo to reach the desired position...
Another one is position accuracy, how precise can the servo track to your desired position.
One more is position repeatability: Is that the servo always can track to your desired position, repeated without bigger offset error or long settling time...作者: Simon 時間: 2011-6-13 21:13
