Brushless ESC

Bro, I can understand motor can be brushless, but ESC is all electronics with no moving parts, is there such thing as brushless ESC. If there is do I always need brushless ESC to go with brushless motor?

brushless ESC = Can be using for brushless motor

If there is do I always need brushless ESC to go with brushless motor?
Yes

brushed ESC = no phase change ( only 2 wires)
Brushless ESC = always phase changing ( that is why 3 wires is necessary )
Hope this helps

brushless electric motor requires a brushless ESC.

ESC sends AB, BC, AC, ... (repeat) pulses to the A,B,C phases (thus 3-phase motor) to create electo-magnetic fields inside the motor.

I just checked, there are always 2 wires going to the motor and 3 wires connecting from ESC to receiver, does it look like brushless ESC and motor to you?

Here is a pix for it

Excuse me, I have fast fingers...

THIS IS BRUSHED esc !!! ESC HAS ALWAY 3 WIRES CONNECTED TO THE RECEIVER .

You have a brushed ESC:
M+ -> motor +'ve
M- -> motor -'ve
B+ -> battery +'ve
B- -> battery -'ve

A brushless ESC has 3 wires to the motor, labeled: A, B, C.

Now I understand. thank you all bros. Just curious for a moderate upgrade w/o going brushless, you think a black 'fanned pig' would make a difference.

of course black pig is faster than white pig.  alternatively, you can also change to a bigger pinion gear.

so using a bigger pionion gear is like shifting to low gear which let the car pick up faster at thee expense of lower top speed?
