Kain Posted April 22, 2007 Report Share Posted April 22, 2007 Wow, it's been a while since I visited the forum ;D, but anyways. I got my hands on a brushless DC motor as well as the controller for it and I wanted to use it for a non-RC model applications, so obviously in order to drive it I will need to emulate the same signal as the one a receiver is feeding to the motor control. I did some reading and what I figured is that the throttle signal is a pulse with anywhere between 1 to 2ms length and repeated usually every 20ms, in other words - it is a PWM that the servo is looking for. Now I am not RC maniac for now so if somebody is more experienced with this stuff can you tell me if the speed/direction is controlled by the pulse width only? Also are the motor controls looking for any other sequence besides the PWM signal? Any help is appreciated. By the way - I did a simple PWM setup with PIC which provides pulse width between about 1 to 2ms adjustable and repeats every 20ms. It consists of only 4 parts so if people are interested it can be added to the project section since it is as simple as it gets. :) Anyways, hope to get some answers on the question above. I know that Audioguru has always something to say (this is in a good way btw ;D). Quote Link to comment Share on other sites More sharing options...
