Greetings, Large Scale Comrades,
I have a re-motoring project in mind and I would appreciate any pointers! Here are the details: I run Marklin 1 gauge. I have an Intellibox digital controller. I have one old Marklin analog engine that I would like to digitize. But the motor is A/C. I would like to re-motor it with a D/C motor, then digitize it.
There seems to be plenty of room to work. The engine is vintage 1990 or so. Very simple. The A/C motor sits crosswise. The pinion gear has 10 teeth. The idler gear has 37 teeth. The driver gear has 45 teeth. The new motor could be as big as 30 mm by 60 mm, but I’d like to use a smaller one if possible.
Motorman, a very nice supplier of surplus d/c motors has been helping me. I’ve yet to choose a motor, because frankly there are so many to choose from! I’m a bit immobilized by all the choices! But here is my current “plan of action” and if I’m way off, I’d love to know!
-Don’t buy a really expensive motor - it would be overkill in such a basic engine. Top budget: $30.00, maybe $40.00,no more.
-I don’t care about tons of power. I won’t ever pull a lot of cars with this engine.
- I do care about very, very slow and smooth running. Like 1 scale mph, without any cogging.
- I had thought about ordering a duplicate 10 tooth pinion gear and having it pressed on. That way, I could go back to the original engine.
- I don’t know how to figure rpm on the A/C engine. I don’t want the top speed to drop.
- I THINK I know enough to start muddling around, but I’d sure love to know more about the technical principles involved.
Many thanks!
Tom C.
