BLDC efficiency: damping, braking etc.

Analysis (experimental and simulation) of the BLDC efficiency. The answer why BLDC-driven copters have low efficiency found!

DC brushed: inductance and PWM frequency

Based on my recent theoretical model experimental data are analyzed, motor inductance is determined and data are fitted vs PWM frequency

Raw data for thrust and efficiency for brushed 0716 (17500,19000), 0617(25000) and brushless 0603(17000,19000)

Detailed experimental results and theoretical fit for 0716 brushed motor loaded with 4, 3 and 2 blade propellers.

Testing brushed 0716 motor. Preliminary results. Some problems with theoretical model solved, firmware improved.
