What the charts show: The curves show the motor's behavior at every speed for a given throttle input. With the default 100% throttle, the chart corresponds to a full-throttle acceleration from 0 km/h: follow the curves from left to right to see torque, power and currents until the speed levels out at the equilibrium speed.
Interaction: Hover over or tap a chart to inspect data at different speeds, and all panels follow along. Click to lock a speed. The vertical line shows the selected point or the equilibrium speed.
Physics model: Three regions: phase current limited (I_fas = limit), battery current limited (I_batt = limit, solves R×I²+V_bemf×I=I_batt×V), and voltage limited (D=100%, I drops linearly).
Disclaimer: The simulator is based on a simplified physics model, and all results are theoretical estimates. Actual performance, range, consumption, and other values depend on many factors and may deviate from what is shown here. The values are provided for guidance only, without any guarantee of accuracy, and GBIKE accepts no liability for decisions made based on the simulator's results. Always verify that your vehicle complies with applicable laws and regulations.
