I'm interested in sourcing an IP67-rated 4-inch motor that operates at 24V and has a power rating of 100W, suitable for handling a load of 50Kg. This component will be a key part of my robot design project, so ensuring its durability and performance in various environments is crucial. Additionally, I would like to request a CAD (Step file) for this motor. Having the 3D design will help me integrate it seamlessly into my existing plans. Please let me know the availability and any relevant specifications or details that could assist in my decision-making.
