26 cze 2024 · Calculation Formula. To approximate vehicle speed based on motor speed, you can use the formula: \ [ \text {Vehicle Speed (km/h)} = \left ( \frac {\text {Motor Speed (RPM)} \times 2 \times \pi \times \text {Wheel Radius (m)} \times \text {Gear Ratio}} {60 \times 1000} \right) \times \frac {3600} {\text {Losses}} \] Where: Motor Speed (RPM) is ...
