most ESCs can't run the motor in two directions. if you send 1ms pulses the motor does stop, if you send 2ms pulses the motor will run at 100% speed.
I have programmed motor controllers using PWM, so if you need help, just ask me.
BUT: there is a…
Thanks for your help guys, I think I finally got it right. The three cables do go to Power, Ground and the control signal, which must be a PWM from 1 to 2 ms I can generate with a microcontroller. I investigated a little bit more about the reverse a…
Alex,
You are going to need a servo driver like this: www.lynxmotion.com/Product.aspx?productID=466&CategoryID=113
to control the brushless motor through the ESC. The servo driver will provide PWM from ~1 ms to ~2 ms. You can use the servo driver…
Hey, well I'm talking about a brushless motor ESC... I saw a picture of it showing how it must be wired up and it has 2 cables going to the battery, 3 cables for the motor, 2 cables to an ON/OFF Switch and then 3 cables which I assume are the ones y…
Hi Alex,
are you sure you are thinking of the same type of ESC the others were talking about? Based on my limited RC experience I'd say that an ESC has 3 cables connecting to it, ground, power and the signal, where if the ESC has a BEC then it actua…
Hello, I know this post is quite old and maybe you won't answer but I still have to try.
I'm a mechatronics student and I'm currently working on a kind of important project. A few weeks ago I learned about brushless DC motors and decided I would us…
Hi, Bill:
So if I connect ESC to Radio 1 and connect the Rudder and Elevtor servos to Servos 1 and 2 on the UAV board, I should be ok to modify the code and to drive the servos, is that right?
Thanks
Hi, Bill:
If I want to modify the firmware in UAV board WITHOUT connecting RC receiver to the board, can I use ESC to power UAV board directly? I mean to connect +5V and GND of ESC to the VCC and GND on the board. I have a 3s Lipo battery (11.1V) w…
