I'll apologize in advance for a fuzzy question. My problem consists of two parts.
For starters, I'm trying to buy a DC engine for learning purposes and most of them only specifies the watt (which I can use in order to convert and get the horse power that I'm normally used to) or torque. And secondly, I've never built something like this before, usually I build bikes or cars. Normally engines are pre-designed to haul a car or two but when it comes to DC engines I could accidentally buy something that's meant to drive a overhead crane.
What torque would be required to match your run-of-the-mill go-kart that you usually find at theme-parks or amusement parks (I understand that a 70 bhp go-kart doing 120mph is another ballpark)?
Would 1.9 Nm be enough? Sounds weak when my bike weighs 196 kg with 96 Nm does 0-60 in roughly half the time a normal go-cart reaches it's top speed.
Could 1.9 Nm be enough to accelerate 130kg as fast as a "normal" go-kart?
I have no place to ask these silly questions and no friends to ask, that's why I'm asking these vague questions here. Again I'm sorry!
