servo motor

[kaptain Jack]

Was wondering if any one tried to use servo as a switch? I'm building a goose neck for flat bed and wanted to use servo minus the motor,but connect my motor of the goose neck drive instead,this way with my Radio I could turn unit up and down.Will it work?or the load of my motor will kill the servo board?

That would depend on specifically what the amp rating of what the servo board could put out vs the max amp draw that the motor would use...

This is a DPDT switch

This a capable, small esc

The double switch won't work as a speed controller, it has no neutral position for stop. It is either one or the other.

Best bet is the ESC.

Ah yes, my bad... mis read the script "The relay is a double pole double throw switch."... that's one for Travy. :D :p

Thank you, for the feed back.

Will the ESC work for what he is wanting to do. It sounds like, and I may be wrong, that he would need to be able to operatae the motor in both directions which would require an ESC with a reverse option so the motor can be operated in both the up and down directions. If there is a way to do that with one of these airplane ESC's If so, I would love to know how to do it as this is something I have tried to figure out in the past and an ESC with reverse function for brushed motors are kind of spendy.

With respect to servo, I removed the limit pin and now when you push the stick on the radio,the motor turns in one direction,until you change the position of the stick and then it goes the other way until you let go.When the control stick is in the middle (neutral) there is no current to the servo.

that esc is only forward only. im guessing you need it to go the other way to. one to lock and one way to release?

I use the controller from a constant rotation servo (no limits) to power my gooseneck. I'm not too concerned with drwing too much amperage, it's a 6 volt gear motor w/a pretty significant reduction and the motor never really has to run for very long...

see my video on this post...

Ah shoot! 2 for 2 :o forward only yes it is :o ..good to know ppl are double checking the info. ;)

pssst, kaptain Jack, mind if I delete the thread/evidence and you start again? ;) j/king :D

Decent capacity, decent priced brushed esc's are becoming difficult to find with the seemily onset popularity of brushless, but here's one that would probably work fine.. and it is reversible too.

Several ppl have used continuos rotation servos in many of a Bruder constr model conversion... whether or not it fills the bill for your needs depends the amount of weight/stress you intend to lift vs the power/gearing/tpi screw rod.

[kaptain Jack]

By all means,go ahead and delete it.

Good, video,simple and elegant.
