Calculate DC motor specifications (torque power etc) for electric vehicle?
I want to make an electric car like as shown in figure below., with a DC motor. assume no inclination, road is plain surface. please explain all calculation with formulas. Thanking in anticipation
following is the basic known parameters:
Total mass of car(including rider and everything) = 170kg
initial velocity of car = 0 (still car stop)
max velocity = 30 km per hour
time to reach max velocity = 1 minute = 60 seconds
radius of tyre = 8 inch
please tell me how could i find the following parameters to find accurate DC motor for my car:
how to calculate force needed by my car?
how to calculate torque needed by my car?
how to calculate speed RPM of a motor needed by my car?
how to calculate power (watt) of motor needed by my car?
