Hello guys !
I’m using the Myxa 0B with telega v0.2 for a quad copter UAV.
I’m very please with the ESC controler and its small SWAP.
I’m using a lithium-ion battery (full charge: 25.2V - empty: 18V) and due to it’s low empty voltage (compare to a classic lipo : empty voltage ~20.5V) the motor can’t deliver the require rotation speed I need when the battery is 2/3 deplete.
I would like to use that remaining third but to keep control of the UAV the motor need to be able to reach a maximum speed of 5400RPM. From my test I can reach that maximum rotation speed with an input voltage of 21V (Motor KV = 487).
To reach 5400 RPM at 18V, would it be possible to use the field weakening function ? Is it recommendable for a multi-copter ?
How can I use it correctly ? It look like it required some attention (Max current/watts power data sheet discrepancy)
From this post Voltage Utilisation Factor telega v0.3 has a better maximum phase value (amazing news !), so updating the firmware would improve this problem ?
Thank you for your answer.
