I am in the process of building an electric go kart, and I came across the expenses associated with such a build. I noticed that motors in the 4kw range are pretty expensive. My only option for keeping the price down would be to get 2 - 1.8kw dc brushless motors instead (about half the price, even though it does not reach 4kw, pretty close).
This is the motor in question: https://www.ebay.com/itm/1800W-48V-...AOSw011blk6z:sc:FedExHomeDelivery!78641!US!-1
At this point, my questions are as follows:
1)Would using 2 motors be a good idea? I imagine one motor spinning slightly faster, or one starting to spin before the other, creating some kind of damage from unmatched rotation; am I wrong in thinking that?
2) Would 2-1.8kw motors give me more speed over just 1 of them? In that case, how? Again, I imagine them spinning at the same speed, so no gain there; maybe the torque would double? How would that contribute to increased top speed?
3) If using 2 motors for the 2 back wheels is plausible, should I use a single axle with both motors connected, or should I give each wheel its own little axle? Why?
On a side note, all replys are welcome, but please try to answer the post questions in your comment (to avoid more confusion).
Thanks for taking the time to answer!
