I want to know if you can control the speed of a winch that normally turns at one speed? thanks

So 12v it will be DC, but it could be brushed motor or BLDC, either can possibly be controlled using PWM.
But you will lose some power with the PWM reduction so it all depends on load.

Lots of 12V PWM controllers on Ebay. If yours is a 'brushed' motor then there's loads of solutions.

ok before you RTFM on me, I'm on it
so nowhere in the manual or extra information does it mention brushless or brushed no mention of brush, is there any other way to determine what type of motor is inside? thanks!

I suspect it may be 3ph brushless (BLDC) as used now on motorized bikes etc.
If the rear end is vented, you may be able to spot if it does indeed have brushes or not..

Theoretical current draw at the rated output is 114A. Peak (start-up/stalled) current will be greater, probably a good bit greater. You'll need a hefty PWM controller! Also a good battery.

Any suggestions on a PMW controller that would suit, I would preferably like one that could handle 30% extra than what is needed, cheers

To begin with, you have not yet determined what type of motor it is.
If it is 3 phase brushless, you won't do it with PWM.

If it is a brushed type motor, you certainly will not find a pwm device on Ebay capable of those currents, at least not of any ,what would be considered, quality.
If you do find any off-the-shelf pwm controller capable, be prepared to pay many times more than the cost of the motor.

As my grandfather used to say, if you want a Ferrari , buy a Ferrari.

ok I'll get the motor type first of all

Please supply the community with a minute by minute update.
Much appreciated.
joking or serious?

So this leads to the next question if it does turn out to be brushed type how would I go about making a PWM controller capable of handling those currents? thanks, and IF it's a 3 phase how would I make a speed controller for that!!??

That’s not an update.
That’s more questions before you’ve answered the first!.
Keep on track and find out what motor you have first.

Ninja 3500 Electric Winch - Steel Rope (12V)​

and should have an update soon with the type of motor inside the winch!
feel free to call them first 0115 956 5555
