How do you estimate motor torque and efficiency from basic measurements? It is useful to know this information to improve flight time and performance. The video explains the fundamental relationship between Kt and Kv. It turns out you can get a lot of information from the motor Kv.
This video is part of a series. There are more tutorials on the tutorial page of our website. I transcribed the full video, so you can turn on the subtitles.
The following videos are written and will discuss experimental Kv measurement and brushless motor construction. They may take a bit more time to make because I am working on animated graphics. I think those will really help, especially to explain the relationship between Kv and motor/esc timing.
If you have any question about motors, I can answer here, and I will try to include the asnwers in the following videos.
