Considering the situation where:
- A non-waterproof motor is used inside a waterproof box
- Something must be rotated by that motor in a wet environment outside the box
What is the correct way to transmit the rotational power from the motor to the exterior environment?
Notes :
- Rotation speed 1-10 rpm
- Exterior environment has constant low power water spray
- Low cost is a priority
NB : Apologies for using incorrect engineering language. I do not have an engineering background. I invite anyone to correct my words as appropriate.
Thank you Elliot
