Drone and RC airplane motors – everything you wanted to know but you were afraid to ask!

Today, let's have a nice talk about brushless electic motors we use in the RC hobby. Both on airplanes, as well as on drones. In this video we will discuss:

  • motor size
  • motor KV and rotation speed
  • KV versus KT as motor constants
  • stator and rotor
  • number of coils and poles
  • winding
  • phases
  • airflow and cooling
  • does a motor care about rotation direction
  • how to change the rotation direction of a motor
  • shaft and hub
  • mounting holes spacing
  • how not to fry your motor right away
