Alternate motors with anti-backdrive systems

[inphiniti]

Hi all,

I'm looking for motors that have a mechanical anti-backdrive system to the DeWalt gearbox or the Denso window motors for a research project. The DeWalt motor+gearbox fits a little too oddly, and the window motors are difficult to find.*

The AndyMark snow blower motor looks like it would be useful, but I'm unsure of whether or not it has an anti-backdrive mechanism. It looks like it's worm-driven which is nice, but it'd be nice to have a more direct system like DeWalt and Denso. Along similar lines, this window motor from Robot Marketplace looks great as well, but I have the same uncertainty.

Does anyone know of other transmissions or motors that have anti-backdrive mechanisms?

Much appreciated,
-Ron


*Other window motors are easy to find, but are the FIRST supplied Denso motors the only ones that have the anti-backdrive pins? I've done some extensive searching and CD is the only place where these mechanisms are mentioned with regards to window motors, and it's specifically for the kit motors.
