I have a problem I am hoping someone can help me with. I am designing a moving cart that will need to transport a 2000 lb load from point A to point B. The speed of the cart will need to be approximately 2.3 MPH. I have done some initial calculations. If the electric motor were to spin at 2500 rpm, I would need to reduce it by a ratio of 39.06:1. The gear reduction calculation was based on the spur gears driving a 12" tall tire. This gave the final drive speed of 2.3 MPH. Considering this ratio of reduction, what horsepower requirement would be needed to achieve this. Second, if the cart had to travel up a moderate slope of say 9 degrees, what power requirement would then be needed.
Can anyone help me with these numbers, as the math involved is just simply is over my head. Or if anyone knows if there is a spreadsheet or calculator out there that I can put my numbers into get the appropriate results. The variables in this project may change slightly, so it would be helpful to be able to figure it out myself.
Thank you in advance for any help!
