Powering A 360 Degree Feedback Servo

Post by doylep »

Hi all!

We're using a 360 degree feedback servo to rotate a large wooden arrow. When the servo has no load (i.e. a paper arrow), it rotates accurately to the correct position. However, with the wooden arrow installed, the servo occasionally does not make it to the correct location.

I assume this is because we're powering the servo from 5V (the spec recommends 5.8 to 8V). Since 6-8V are not a typical supply voltage, what is the best way to get a reliable source of 6-8V? Since we will run this arrow regularly, it is not feasible to run it using batteries.

Thanks for your advice!

You can get power supplies in 6 and 7.5 volts fairly easily. Also, make sure you have enough current in your supply as that can also affect the behavior.

Thanks Franklin! I typically avoid wall warts, especially for our permanent installations, but this should work fine for just running one arrow :)

If we add more devices, I will probably switch to a LM1085 regulator to bring down the voltage from 12V.

Thanks again!
