I have found a simple way to attach non-Lego motors to Lego components. I just use a band clamp as is used in plumbing to tighten the motor against two Lego axles.

I glued a couple of the thin Lego strips to the bottom of my HandyBoard to make it quick and easy to plop the board firmly onto a Lego base yet still have it easily removable. Doing this you must be certain to get the correct Lego spacing, so first (...) (26 years ago, 28-Feb-99, to lugnet.robotics.handyboard)

The LEGO purists may not approve of this, but it does work well and it makes it relatively easy to use non-LEGO components. You *do* need to be cautious about what type of glue you use. Many glues will not adhere to the LEGO plastic, others will (...) (26 years ago, 28-Feb-99, to lugnet.robotics.handyboard)
