Can you slow down a servo winch?

[jebster]

I have an existing servo winch made from a hitec 645mg servo and heyok 3 position controller with a spool. Had this a long time and it works great but the spooling speed is just too fast. I'm using the winch to raise and lower implements on the front of a 6x6 rig (plow, snowblower) and I find the winch speed to be too fast for fine control.

Curious if anyone had suggestions? In the end I may have to look at something like an rc4wd winch because I know the line speed is slower but I hate to give up on the power of my existing setup.

Any recommendations are appreciated.

you might be able to lower the voltage

a smaller spool would slow it down too

if you have the abulity to set the end points on the channel or program that channel to 50% power and only run at part throtle

in the end its just a motor and esc inside a servo housing

if you use a cheap speed controler to control the winch you can set it up to pull at any speed you want
ive herd some of the micro 1/24 escs have the foc like control if you realy want to go all out

Us a HW 1060 esc as your controller, by setting your EP you’re adjusting spool speed


Hang up and Drive

I’ve seen plug in modules that slow down servos for planes, not sure how well it would work in combination with the HeyOK controller though.

Isn't FOC for brushless motors only?

Thanks for all the ideas so far. A few things I forgot to mention. The channel on my radio is a 3 position slider vs a lever or dial. It doesn't have EPA capability. I had thought about a cheap ESC but being 3 position with EPA i wasn't sure that would work.

Buy a better radio?

Any way you do it, you existing servo will produce less power if you don't use gears to slow it down.

honestly i dont know but i think it works for brushed motors maybe not the same way but close i do know there is a micro esc that is foc like and it runs both brushless and brushed motors but i dont have one

also i dont know if his servo is brushed or brushless

if he uses a smaller spool it will both slow down the line speed and incress torque at the same time its kinda like gearing down

What voltage are you supplying the winch controller, and how is it getting from the battery to the controller?

 

[heyok]

I make a version of the winch controller that has variable speed. To set the speed, you adjust your end points. Or, if you would like, I could make one with a trimmer pot that you could rotate to set the speed. Just send me a PM or an email and we can work this out. Email is mostlyal@gmail.com

It runs off the rx so it would be 5v.

Pm on the way.

Hi....In case I wanted more hat, and more slow speed, I would equip the result shaft, IE supplant the horn with a stuff and assemble a mount for a mating gear. A standard servo won't work in view of the restricted travel, however a winch servo may very well fill the bill. It has around a few turns on the drum which could be supplanted with a stuff and if you arrangement a 9 to 1 stuff proportion, you could check out force and much more slow result on the last shaft. a 9 to 1 proportion would give you around 120 levels of development for a three turn winch servo at multiple times the force.

Presently, is a servo what you realy need, or do you want a stepper engine with driver?
