Hello, we have a question about a motor that we want to use because it has high torque. We are not sure of the model because the identification is worn, but we believe it is the bosch 006, as per the following images. But we are in doubt if it is allowed.

It’s definitely a van door motor of some form. There’s a chance it matches the part number for automotive motors in the rules.
The one listed in the 2023 Rules is the Bosch 6 004 RA3 194-06. So if that motor is this part it’s legal

Markings look badly worn. It might not be possible to show that the motor you have is the legal one by reading the label. If not, it might still be possible to show it is equivalent by test.
Years back there was a Taigene van door motor in the FRC kit of parts. This test data was provided by WPI for that motor.
Is there similar data somewhere for the Bosch van door motor?

That’s a lot of torque… do van doors need that much torque?
I plotted the WPI data below. I don’t think a van door needs the full stall torque (42.8 N-m) but it helps to have extra in reserve when mechanisms get sticky. Likely the design load point will be somewhere near the data that I boxed in red, so about 8.6 N-m drawing 5.8 Ampere. That is the way i would recommend an FRC team load this motor back when they were in very common KoP use.
Students being students, they went more aggressive with the loading. The main constraint was not to load the motor beyond about 40% of stall current, so about ten Ampere in this example.

Well, they are supposed to be child-proof.
I wonder how much weight you could lift if you put a 100:1 gearbox on that.
I know we didn’t have any trouble climbing with a van door motor coupled to a approx. 1/2-3/4" lead screw wire-guide coupled to it in 2004, so 100:1 would be a lot.
We used a very slight reduction on ours for a bar slider.
