但用不同A數輸出的電變
咁大A數輸出的電變會否比細A數的電變快作者: jacobchu2007 時間: 2007-11-2 22:18
The speed should be no different for thesame motor.
A faster motor will need an ESC of higher Ampere output so that enough power can be supplied. If a fast motor is equipped with a ESC of small ampere, then there is not enough power to supply. The fast motor will be slow.作者: tungkee 時間: 2007-11-3 04:06
我個人覺得會快ddddddd,但你會唔覺。
通常輸出細既esc的內阻比較大,電壓降亦比較多,有部份POWER會消耗左變成熱力,電流愈大就愈熱。所以能力許可就買個靚d既 esc。
1. Theoretical, you are right.
2. The amount of current depends on the supply voltage and internal resistance of battery, esc and motor. Obey the simple ohm's law, I = V/R. As the internal resistance cannot be controlled, you can only control the current by adjusting the voltage. However, you cannot provide a voltage higher than the norminal 7.2V.
