Title: How can one direction rotation be achieved?
Post by: scientizscht on 16/06/2018 19:11:38

Hello!

What strong and reliable and efficient mechanisms exist so that a shaft can rotate in one direction but not in the other?

An electric motor.
Just tell it the direction you want, and don't tell it the other direction (until you want it).
