DC Spot Welder: Types & Models

Does anyone recognize this designation for an old DC motor with a built-in controller?

LJ/REE/75/12/1800 CR1

I can already make some sense of the numbers.

12 volts and 75 watts of power at 1800 RPM? (hopefully that's correct).

However, I can't correctly associate the letters with their meanings (I understand that they indicate things like the construction type/size/direction, etc., but that's all I know).


Sorry for the extremely off-topic comment.

Oh my goodness... Beetle sends their regards.
The Porsche down in the courtyard also has something like that .

Do you know the manufacturer?

'75W? That seems like a little bit... my scooter already has 350W.'

It must be a Bosch product.

So, the 75W is definitely correct – I figured that out today.

Are you absolutely sure it's Watts and not Amperes? 75W is such a low amount of power that it could only come from something like a moped.

For comparison:
- Headlights (55W) +
- Rear light (10W) +
- Brake light (21W)
They would already be 86 watts... Also, a normal car has two of them. } Besides, the motor isn't even running yet.

He's right...

That part actually has 75W at 1800 rpm .

The only clue I found refers to an old Kramer tractor from the 1950s, which used this type of generator.

I haven't found anything on the Bosch website yet.

Here is the link: http://perso.wanadoo.fr/tractopassion/tractopassion/KL_22.htm

Let's assume:
2 headlights, each 15W.
2 front fender position lamps, each 4W.
2 tail lights, each 5W.

They together provide 48W. The diesel engine doesn't need anything. There are still about 2A available to charge the battery. That should be enough. The development of this tractor probably took place shortly after World War II, and at that time, they saved wherever possible.

I can't imagine that, even if it's a pre-war tractor... either they had a really adequate power supply, or none at all (due to cost-saving measures). By the way, 75W is less than what a Mofa has, I think. My Vespa ET2 50 scooter, according to its manual (!), uses 120W. It also needs enough charging current so that the battery (4A) can handle the next start.

Well...

There isn't that much electricity available there. Turn signals and parking lights are sufficient.

My moped, by the way, had 19W .
