Estimate torque and efficiency from Kv

Posted on February 15, 2016 at 10:30am 5 Comments

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…


Improving motor and propeller performance: theory and application (part1)

Posted on January 25, 2016 at 4:27pm 17 Comments

As promised, here is part 1 of our series on motor and propeller theory. Part 1 covers the coil magnet model, Kirchhoff's law for a motor, Back EMF, Kv, Kt, and motor efficiency.

By the end of the first video, you should really understand why is a motor is inefficient and the relation between electrical power, heat and mechanical power. The motor model is…
