Motor design

Carry out field trials.

"Simples!ξ"

What? No calculations? How would you know if you are even in the ball park??

Since there are so few people who are familiar with this specialized field you would probably be best to look at existing equipment used to accomplish this task. This could then be used as your basic information to develop your specialized unit.

On this type of forum it it is difficult to "skim" the "wanna' knows" and "I think" and "know everything" types from the people who really know. Have some basic information yourself so you can cut out the BS from the replies you will get.

Also, the answer you want won't be very useful because you haven't included enough information to deduce an answer accurate enough for that which you want. Answers can only be as accurate as the information provided.

I'm not trying to be derogatory, just trying to help you get the answer which you apparently are looking for.

Good Luck, Old Salt

Thank you, Old Salt I'm abit lacking on how to get an answer or fundamentals form forums in general (my wife would say, a bit rough but meant well). Im trying to supply all required information to solve or ball park an answer but truly do not want to appear as a hand out, I do want and desire to understand. I was also thinking that there was too many variables to find desired torque output required, not too few. Or maybe I was not clear on the given variables? Even knowing how the process of evaluation, is a start or maybe Im asking for too much, what do you think? PWSlack, Is right in field trials, but I need a completed theory or equation to show client its worth investing to build and running trials. (the money to buy the horse to pull the cart) Thank you and you are well spoken
