I am working on a project that requires a wing to be rotated and I need the rotation mechanism to be fail-safe -- if power fails, the wing will stay in place and not move around. My thought was to use a worm drive since they are not reversible. However, worm drives typically reduce speed.
Would there be anyway to make this reduction in speed from the motor to the gear as little as possible using a worm drive?
Should I just forget the idea of a worm drive and use a motor that can hold its position even if turned off (if so what type of motor could do this?)?
