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

 

[telectrix]

what wattage or amperage is stated on the motor?

 

[Marvo]

This kind of hydraulic pump motor could easily be 50Amps at 12VDC, the losses will be high with 30 foot leads at the best of times, what cable were you using. The power required is alos probably way too high for your inverter.

Can you attach a few pictures of the motor and solenoid and hopefully we can see the info sticker as well if there is one.

 

[markus19]

here is a few images

 

[Marvo]

Okay, if those blue wires that look like they've had a haircut when they were stripped are supplying the power then they're grossly undersized.

You need wires similar thickness to decent jumper leads and you need to keep them short as possible (<1meter preferrably).

You can post your inverter details but if it's a little camping type inverter then it's way undersized. That motor could be between 25-50Amps at 12VDC.

Why is the end of the motor missing?

 

[Guest111]

that unit is going to pull some serious current,best thing is buy a 12v car battery and use that close by the pump,a battery would only cost about £40,you'd end up paying at least double that for a transformer unit to power it.

 

[HandySparks]

Looks very similar to a car starter motor. Loads of current!

 

[markus19]

hello

the two power supply cables are the green and yellow (which is neutral)
and the black one which is live the blue cable is what i presume went to a switch to switch
it on and off

the black live goes onto the solenoid and the neutral onto the solenoid housing that bolts onto the motor housing

and then there is one blue wire from the solenoid with the live and then one blue wire on the other side of the solenoid theys wires need to be connected for anything to happen


this motor bold onto the side of the pump direct none of it is missing

 

[Marvo]

Don't try run the motor without it being bolted to the pump then, it's likely to destroy it.

Hi,if the motor ran off the pump,check the hydraulic pump is not seized or stop-ended hydraulically. Can you turn the pump manually? When you connect the two up,all being well,do not run the unit too much without oil in system. Also,things like temperature,oil viscosity,cable CSA and length,will all affect amps drawn,which under load will be heavy. Good luck

 

[markus19]

ok guys it seems that i havent been giving the motor

enough power...

i dont really want to power it from a battery as i dont think

the battery would last long

i want a way of powering it from the mains but i

need to know what gear i would need to do this and also

how many watts or amps i need to power it up

thanks

putting the part number in google this comes up
which is just like mine

i see what you mean now there is abit missing abit that
goes across to hold the coil central some one must
of been fiddling....

 

[Knobhead]

A hydraulic pump should have a bypass/unloader valve for it to start. Otherwise it will be locked rotor current you have to deal with. A displacement pump has a swash plate to control the flow/pressure.
I’ll be honest I’ve never dealt with a pump this small.

I’ll help if I can.

 

[HandySparks]

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

 

[markus19]

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

 

[Geordie Spark]

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...

[itselectric]

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.

 

[markus19]

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:

 

[PEG]

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 ??

 

[PEG]

It is probably a generic tipper pump unit,relatively low pressure,low flow and very intermittent use,off the likes of a transit or similar. Any decent log splitter will require 180 Bar,75% + duty cycle and sufficient Lpm to stroke a fair capacity ram its cycle quickly. There are some good engine driven yokes about and i have made several over the years. If you have anything plant-like,you could drive one via SS couplings off an auxillary circuit,as on a tractor,stacker or beaver type power pack. Me pal has a german creation that cost five figures and is directly driven off a large John Deere tractor,but it splits logs up to 3ft long in to staves,then will cut those as short as you like. If you are splitting for your own log burner (my folks have one),then you may have to accept that the cost of kit like a chainsaw,splitter etc,is the bit no-one mentions during the start of the job. Don't be annoyed if the thing you have turns out a non-starter,before i met my lovely missus,i had a rake of pretty girlfriends who turned out needing help to cross a road...:shades_smile:

 

[markus19]

Here is a couple of images of the unit i have bought

this image is with the motor removed.

so use dont reckon this will be have enough power to run a ram to

split logs.....

 

[Guest111]

Toolstation do a mains powered log splitter for about £200.

Only replying because your pictures are so good! That looks like a fabricated unit,possibly for a pipe crimper or similar,the functioning spool is set up for a single acting cylinder (spring or gravity return),whilst the double acting spool is blanked. It will be low flow/duty due to its power source,a single or banked 12V source. I have used an almost identical rig for a vehicle mounted spectacle lift where the lift cylinder was single acting and the spare spool actioned the extension cylinder. All it will do for you my friend,is give you a splitting headache......see what i did there....:smile5:

hello

thank you for your response so you don't reckon this unit is any good at all for making a log

splitter with ?

i was hoping to just buy other pipe rig it up to the blank plate

and buy a ram and it would work fine...

here are some more picture of the setup

Forget trying to make logsplitters and take up photography instead.
