Throttle control motor gears?

[matthewdenny]

I am not familiar with these motors. What advantage would they have as opposed to some of the more commonly utilized motors. Do they have a characteristic that sets them apart and makes them worth this trouble?

The biggest advantage to me is their availability. Almost every year we get at least one of these in the KOP (this year we got 8!) and they just keep piling up in our work space. A gearbox that utilizes these would allow for what is currently thought of as useless (or virtually useless) motor, to become a useful one. I doubt that teams that can afford multiple versaplanetary's would opt for this option, but for teams with less funding/experience, this could be a viable option for low power requirements.

I would like to get rid of 19 of these motors. They are just taking up space. Never been used! FREE! PM me if interested.

I'll take them!

We have I think 17 years worth. I wonder how many that is? I don't think we've ever thrown one away.

sdp-si sells gears that will work. When you go to the catalog, be sure to select "Metric" instead of "Inch". Choose a spur gear with 0.75 module (metric equivalent of diametral pitch) and with 20 degree pressure angle.

Not quite, diametral pitch is # of teeth/diameter (in inches) whereas module is diameter (in milimeters)/# of teeth.

By "equivalent", I meant it conveys the same information, which it does.

That's true. I just clarified because it could have been a bit misleading to someone new.
