I'm working in a project that consists of something similar to a motorized skate. I know how to do it, but I don't know what motor to use. I need that the skate to be able to move 90 Kg to 20 Kph (12 miles per hour) or more if it's possible. I also need the motor as cheap as possible.
I have read things about motors but we can say that I don't know anything about them.
What kind of motor and what facts do I need? What transmission ratio should I use between the motor and the wheels? What size and type of wheels? Any special type of transmission?
I know the basic mechanics, but I don't know what motor should I use, my requirements are:
- Move 90 Kg to 20 Kph (if the motor for that is very expensive only 15 kph)
- I don't mind the acceleration
- I think that it should work with battery (I'm not sure)
- The skate is thought for city, but may have to go up small slopes
- As cheaper as possible
I don't have the budget to buy numerous motors and try them all, so I need to be sure that it will work before I purchase one.
