hey guys,
I am building an electric go kart for a final project, and I'm just trying to get my initial justifications correct, with respect to the classical physics involved.
SPECS: i was the car to be able to reach 15km/h,
The total weight of the car will be approx 200kgs.
the size of the tires of the car are 30 cm in diamator.
Motor Type: BLDC Motor
Maximum Power: 350 Watt
Max. Operating voltage: 48v
so i need to calculate the torque... at the wheels , and then decide on the gearing ratio! this decision is obviously indicative on the parametors of the motor i have! and the goals i want to achieve! The Motor i have has a max RPM of 4000, and a peak torque of 12NM.
can anyone show me best how to perform these calculations ? i understand that i need acceleration ! can i assume constant acceleration ? if that is the case can i just say i would like the car to accelerate to 15km/h in 10 seconds
... any help will be much appreciated !
Thank You
