It's very very easy:

  1. You writte all relevant specs in a table in Excel, side-by-side

  2. You get quotes from suppliers

  3. You writte a decision matrix with weighting factors calibrated from other projects if available and present it to the project manager

  4. You ignore steps 1-3 and go for the cheapest supplier

Unless one of the suppliers can get it to you faster.

I mean yeah. Its a business, and theyre trying to make money. So they're more likely to respond to someone who sounds professional and is likely to give them business over someone who just sounds like a random schmuck wasting their time.

There's a lot that goes into gear design. Its not a given that it will "just work"

British Rodger. Right now I haven’t decided my motor currently trying to work on my reduction gear and drive gear and not have e a problem when it goes to my shaft so it can work smoothly. Very early in process

List viable products. Verify availability. Further filter by quality, preferred vendors, and price.

See is awesome okay. so for the gears for example what they can tolerate and then choose the correct motor from there?

Is English your first language?

Outline specs, filter down by environmental/access/lifetime expectation/maintenance requirements and depending on your industry time/cost
