A sensored BL motor lets the ESC know its speed. So the ESC can adjust the output accordingly to match the throttle. A sensorless BL motor has no information to feed back to the ESC and so the control is less fine.
I can't think of any advantages of using a sensorless motor except that you need 1 cable fewer.作者: andyccf2004 時間: 2011-5-25 21:15
