HiI'm looking to rotate an object (probably going to be an LED lighting system) at 60RPM.I'm familiar with using Arduino, but haven't had any experience with RC electronics.Should I be using an ESC…Continue
I am using continuous rotation servo for 'Yaw' control of my camera gimbal. I am using it for stabilization around a setpoint/ target angle, using PID's.
If I give a target of say 60 degrees, the servo should adjust its…"
"You can get relatively cheap optical encoders (about 30$) that give your Arduino the rotational speed. Simply take the desired speed, subtract the current speed and multiply that by some suitable constant. Output that to PWM and it should work. (the…"
"Ah wow thanks Mike. :)
Also currently trying the mod to make the servo into a simple continous rotation motor, with any luck running it directly from 6V could do the trick.
If I have a continous rotation servo, and run it off a PWM controller,…"
"Meh just realised I'm going to need to use a Arduino controller to send PWM to this continuous servo. I only want it to go at full speed. Would connecting the PWM to DC to make it 100% send it at full speed?"
"The continous servo is specified as moving fastest at 6V.
I am considering using a LM7085 voltage regulator and a 9V power source, and letting the voltage regulator output a constant 6V.
This should maintain a constant speed until the batteries…"
"Thanks for your help.
Can you think of a way to maintain the same speed... I'm thinking if the batteries run down a little it will go slower, and ideally I would like some way for this to be maintained."
"Just check if the servo will support your rotation speed requirements. Most random servos will be just shy of hitting 60RPMs, and those spec'ed to hit 60RPM might not quite make it with a load. Which is why I chose one that is spec'ed for…"
"If you want very high speeds or want to use a step down transmission, maybe. Adds significant costs, and most off the shelf option will be in the thousands or tens of thousands of rpms, not tens or hundreds, if you just grab some at random. "
