Hi I'm Wayne
I will help you with this
Good Morning

Is this on land or water
wheels or sled
let me know please

Customer replied 290 days and 9 hours ago.

It will power a tire on a wheel of a trackless train. Here is a different way of posing the question:

How to build a trackless train and how much horsepower needed to pull 1500 pounds 5 mph. How many 12 volt batteries are needed to create power for the horsepower engine.

Thanks!

If you need any more info, just ask! (Also, it will be connected to a gear to power a wheel and sit on a thick plywood base.)

Hi

If the drawbar force (F) is measured in pounds-force (lbf) and speed (v) is measured in miles per hour (mph), then the drawbar power (P) in horsepower (hp) is:

P / {\rm hp} = {(F / {\rm lbf}) (v / {\rm mph}) \over 375}

Example: How much power is needed to pull a drawbar load of 2,025 pounds-force at 5 miles per hour?

P / {\rm hp} = {{2025 \times 5 } \over 375} = 27

Is 15 HP enough to power 1500 pounds at 5 mph? Answer: No. It would require 20 HP.

P/hp = (1500 x 5) divided by 375 = 20 wtolkson41079.5834596875

Hello!

Thanks for your information on this subject! It really helped! However, I do have 2 questions: How did you receive the constant 375?

And also, I know this is kinda a new question, but how many volts (in 12 volt batteries) will it take to power to 20 hp engine for say 3 hours?

Thank you very much!

The motor is 55 amps, and it is 230 volts. How many and what size 12 volt batteries will work in this machine to allow it to run for 3 continuous hours?

Thanks, XXXXX XXXXX coming soon!
