A simple way to choose the best ESC to your drone is, choose the motor and battery before ESC.

ESC meaning is Electronic speed Controller and simply I can say this is the device that controls your drone’s motor speed.

Check motor thrust data tables and find out how much current that your motor gets when its max thrust.

Be sure your amp rate is 30% greater than that number. Also, choose the best ESC that supports your lipo batteries, cell count.

How to choose a Best ESC brand?

Nowadays there is a lot of drone ESC manufacturers in the world. Also, there are very famous ones among hobbyists.

There are hundreds of cheap unbranded ESCs online, buy one of those with an extra one to two.

What is ESC cell capacity

As an above picture, all ESC’s printed their min to a max cell range, be sure to stick with it. If you accidentally connect higher cell lipo into lower cell rand ESC, it will be fried.

A-Main Micro processor

This is like the brain of the esc.This chip taking commands from Flight controller and giving it to voltage control chips in back side.

B-DC Power input

These two cables should connect to your battery.This is the power input of the ESC.

C-Servo connector pin

servo-wire

This connector should be connected to flight controllers Motor signal pins.

If you want, you can use the other 5v with a ground pin to power up your receiver or something.

D-Voltage regulators

As I mentioned earlier these small chips taking command from central processing chip and regulate motor speed.

E-Motor power output

These are the motor output cables. You can easily connect these cables to your brushless motor. You can change the motor rotating direction easily by changing these pins.

Conclusion

ESC’s are of course electronic speed controllers this device controls your brushless motor speed.

I hope that you got to have now better knowledge about choosing good for your drone from this article.
