powering 12v motor

[markus19]

Hi guys

I have just bought a use hydraulic oil pup that runs from a 12v motor



I didnt have a 12volt battery to try it with but i had a 240v to 13v 5amp

Inverter i wired it up via the solenoid but just got a few clicks from the
Solenoid


I then ran a 30ft cable from my 12v battery in my van to the solenoid
But this time just got rapid clicks but no motor kicking in


I then trying wiring direct leaving out the solenoid ... nothing...




i then took the motor off the pump and plugged it direct onto the 12v van battery it fired up


what could i use to power the motor from a mains connection e.g what amps or watts

thanks

How long do you want to run it for, and how often?

hello

i am wanting to use the pump for a ram to split
logs

so i would say around 1 - 2 hours

regardless of how long i want to use it if

i wire it to a battery the battery gonna need charged

which i dont want to do

thanks mark

Get one of these.

NO electricity needed so nice and SAFE to use so no hassle.

Gives you plenty of exercise too.

The only way you're going to get this sorted if wire it up to a battery and try it under the conditions that it'll be used, ie splitting logs. Measure the maximum current drawn off the battery. Then buy yourself a 230V to 12V DC power supply of an adequate rating. This is likely to be expensive.

Alternatively, run it off a car battery, which will provide quite high current for a reasonable length of time (duration dependent on battery size). Then you'll only need a small, cheap, charger to keep it topped up.

How much?!?!?

More like this I reckon...

I think you would be better sourcing a 230v hydraulic unit it probably would be cheaper in the long run

Quite likely. And easier to use all round.

lol

yeah a bought this unit quite cheap without having a good look i was hoping the motor

would be 240v

but it has turned out it isnt...

the unit was the

spool valve
piping
hydro tank
hydro pump
and 12v electric motor

i was hoping i could run it from my generator as it has a 12v output but its only rated to 8.2 amps

which likely wouldn't be enough to power it...

I can pretty much guarantee this motor will draw way more than 8Amps. If you connect it to your generator 12v output you'll either cause the protection to trip or damage the generator. I'd strongly advise against even trying the genny, stick with a battery.

so can you buy such a device that converters 240v to 12vdc 50/60amp ?

what would you say the wattage is on the motor ?

thanks

You're not taking this in are you? We don't know what the rating of the motor is, and we don't know how much current it will draw when used in your particular application. It will need testing, as I said previously. If you don't have the means to do this yourself, you may need to find an electrician (perhaps an automotive-electrician) who has a suitable DC ammeter, to test it for you.

Yes, you can buy a 12V 60A DC power supply:

I'm not saying that this particular one is suitable for your purpose.

yeah but i though after i sent the link with the same motor as i have

someone would be able to till from it

There are no electrical specifications on that listing (except for 12V).
Try sourcing a 230V motor with the same shaft and mounting to directly replace your existing 12V motor, should be around £150, cheaper than a high current power supply, but more expensive than 2 12V batteries and battery charger.

Do you ever get the feeling that you're just farting against thunder here??? :rolleyes4:

You will not get ANY kind of duty cycle with the set up your suggesting. If i had read "log splitting" earlier,i would have said not to bother. Any mains powered hydraulic unit will have a return circuit for cooling,and open centre proportional valving to ensure you get two hours of fun...put it back on ebay and let someone else feel disappointed.

so what are theys unit made for then if there no good to run a ram in and out for a couple of hours ??
