請問一下大家可不可以幫我解答一下:
1. 無刷摩打是不是要配特定的電變?我的電變是futaba mc230cr 可以用無刷摩打嗎?
2. 什麼是有感冇刷??
謝謝大家 希望幫幫小弟

1.  MC230 is for brushed motor, cannot run a brushless motor.
2. That means the brushless motor is built-in a senor, there is a senor cord to be connected to the ESC.

Just a supplement to item 2.

有感冇刷 have a sensors to detect the position of the rotor of the brushless motor. The speed controller gets the rotor position signal via the sensor cable and produces appropriate currents to different phases, totally 3 phases, of coil of the brushless motor. As a result, the speed control of a 有感冇刷 is very smooth and linear, like the brush motor.

冇感冇刷 did not have sensors. The speed controller "guesses" the position of the rotor based on the output current of different phase. As it is an estimation only, the rotor will turn very "unsmooth".
