اسپید کنترلر 20 آمپر DSHOT موتور براشلس محصول BLHELI

An ESC or an Electronic Speed Controller controls the brushless motor movement or speed by activating the appropriate MOSFETs to create the rotating magnetic field so that the motor rotates. The higher the frequency or the quicker the ESC goes through the 6 intervals, the higher the speed of the motor will be.

when the moving magnetic field of the rotor passes through the free coil or the one that’s not active, it will induce a current flow in coil and as result, a voltage drop will occur in that coil. The ESC captures these voltage drops as they occur and based on them it predicts or calculates when the next interval should take place.

LittleBee is using the Silabs processor and fast dedicated driver chips, providing excellent freewheeling and exceptional braking capabilities.

LittleBee 20A is capable of running up to 6s setups. Damped mode allows your motors to respond to throttle decreases much quicker, allowing for more stable flying, and higher response to throttle decreases. Oneshot125 is a different and faster communication protocol between the flight controller and the ESC on your quadcopter. It allows the FC to send control commands to the motor quicker, therefore in theory your multirotor should perform better. The configuration of the LittleBee is very simple. Using your pc and USB programmer, you can change settings and flash the latest firmware at the touch of a button. You will need to download the BLHELI suite, and the drivers required by your USB Programming tool. You can easily spot the fakes, as they come with matte PCB finish, whereas original LittleBee ESC has a nice and smooth glossy finish.
