 Please be aware that the information provided below is intended for practical use, but it should be used with caution. Remember, field weakening, because of its nature, will not be efficient.

+### Peak Current Draw Calculator
+
+- **Torque Amps Calculation**: Users can input their torque amps (\(I_q\)) to calculate the torque component accurately.
+- **Field Weakening Calculation**: By entering the initial flux in A, variable flux in mAh, current max speed in km/h, and start speed in km/h, the calculator determines the flux component (\(I_d\)), incorporating field weakening effects.
+- **Peak Current Draw**: With the input parameters, the calculator computes the peak current draw (\(I_{total}\)), providing essential insights into the system's maximum electrical demand.

 2. Go to the field weakening tab and:
   - Enable field weakening for sport mode.
-   - Configure as follows: 15 km/h, 3A, 1000.
+   - Configure as follows: 17 km/h, 5A, 1000.
   
 The rest of the configurations are up to you. Feel free to explore and set up profiles according to your preferences.If it isn't reaching the performance you expected then consider fine-tuning it to your liking.
