SUMMARY

The torque for an electric go-kart motor can be calculated using the motor's specifications, including a maximum RPM of 1600, an output of 425 watts, and a gear reduction ratio of 10:1. To achieve an acceleration of 60 km/h in 10 seconds, approximately 1275 watts of power is required, which is three times the current output. Utilizing a simulator can provide practical insights into these calculations and the underlying physics.

PREREQUISITES
  • Understanding of torque and power calculations
  • Familiarity with gear reduction ratios
  • Basic knowledge of electric motor specifications
  • Experience with physics principles related to acceleration
NEXT STEPS
  • Research how to calculate torque using the formula: Torque = Power / (RPM × 2π / 60)
  • Explore electric motor simulators for practical application of torque calculations
  • Study the impact of gear ratios on acceleration and speed
  • Investigate power requirements for different acceleration scenarios in electric vehicles
USEFUL FOR

Engineers, hobbyists building electric go-karts, and anyone interested in understanding the physics of electric motor performance and acceleration calculations.

I am building an electric go kart , and I'm just trying to get my initial justifications correct, with respect to the classical physics involved.
SPECS: motor rpm 1600
: motor output watts 425
:gear reduction ratio 10:1
. The Motor i have has a max RPM of 1600, an anyone show me best how to perform these calculations ? i understand that i need acceleration if that is the case can i just say i would like the car to accelerate to 60km/h in 10 seconds. please provide me the best specification with above details,

Although an electric motor can often produce more power for a short period of time, you will probably no be able to reach 60 km/h with 425 W. You would require about 3 times that power to reach 60 km/h in 10 s. Play around with this simulator and read the theory about it to learn more.
