Help calculating max speed of my electric car

2881 Views 13 Replies 8 Participants Last post by  sadcar
What would be the max speed of my electric vehicle? I need a systemic way to calculate this given BLDC ratings: Voltage, Rated Power, Rated Speed, Rated Torque, Rated Current, No load Current, No Load Speed. Also using these constants: Weight and coefficient of friction. There are two motors. We are ignoring any resistance from the shape of the vehicle. The car is in a vacuum.

you will need the gear ratio and the size of the tires, and pick a max rpm point for the motor. You will need the torque-speed curve of the motor for whatever voltage you have.

And the likely corona discharge problems with the HVDC at partial pressures under vacuum.
