Servo trouble

royston02
royston02 over 11 years ago

I wanted to know if a servo left without power in stationery mode (without making me want to turn it) lift the weight?

Eg:- A skateboard. I just want to stand on itwithout it moving. the skateboard is the servo. Will the skateboard i.e servo stand or fall? No battery.

    If you can live with a normal DC motor and use it with a worm gear, it should "lock" when not powered.

    Try this .. Open your browse and enter this in a google search "how does a servo work" the first two results give a good breakdown of how it works. Mark

    Steve is correct with his visual and description, this arrangement will hold very well. The one you linked will not. I would think any manufacturer would be bragging about the fact theirs would be WORM drive so look out for that

     

    Due to the limited turn range of the radio control variety, you would not get much mileage out of adding the above to one of those. But any motor that keeps turning  and having this added should work well
