Making DIY actuator for 1S (#3)

[@ogzknart9551]

Thank you very much for video. İs that means 40ma usage still there is even 960ma free to use in that esc coz I burned one when I did this setup without a resistor. I didnt know I have to use one like you. Can we decrease resistance and make its current usage maybe 250-500ma to boost its power and still do not heat the esc? Thank you in advance.

Sorry for the late reply. I'm not sure if you mean the coil burned out or the ESC burned out, but without a resistor, it would be 3.9V / 7Ω = 0.557A (557mA), which should be suitable for the ESC's 5V/1A. However, 1A is the maximum value, and for continuous use, it’s recommended to set the maximum at 70-80%. You should also pay attention to the coil. If a large current continuously flows without interruption depending on the coil's thickness, the coil may burn out. This actuator is designed for operations lasting a few seconds. It is recommended to cut off the current within a few seconds after the operation is performed.

Thank you for reply, not the coil but I used a servo board (3.7g) and burned it coz I didnt measure current usage of the coil and thought it should not use much of it but it was. So do you know how can I build a servo driver from scratch ? For micro build I wanna build a servo driver and use it with coil actuator.

What circuit board the rudder is connected to?....Is it the one from servo motor?

[@alchemykim]

The circuit is the Micro DC brushed motor driver, which has a few features - cheap, bidirectional forward/reverse running in 5v, 1A. Search in the internet with keywords "DC brushed motor speed contorller". usually the price is approximately between about $1 or less.

Thanks a lot!

Drop the annoying and useless music. Add text to explain. Google can translate as necessary. Thank you.

please ask me. In fact, the important explanation is enough. I don't know what you don't know. and you can turn down the sound.
