Micro motor

Postby Spaceman » Tue Nov 29, 2016 8:49 pm

Hello All

Working on a Ant project that requires the following for its motors:

Max width 35mm (not including shafts)

ideally 3mm d shafts

The standard ant motor (the one on Rorys kits) is a bit too long to put both in line. I was wondering if there was an equivalent to you knowledge that either had a 90 degree shaft or was about half the length. or if there is a dual motor unit that would be less than 35mm wide.

Thanks

You must have a very tight bot if the standard motors don't fit...

There are not many choices of good metal geared motors for ants.
If width is a problem and you can have reasonable size wheels I usually design the chassis and motor to fit inside the wheel as below.

I've been working on a offset geared drive system (minus tires):

Not got it right yet, and it doesn't work as good as I hope. But it's an idea!
