+ * Torque control example using voltage control loop.
+ * 
+ * Most of the low-end BLDC driver boards doesn't have current measurement therefore SimpleFOC offers 
+ * you a way to control motor torque by setting the voltage to the motor instead hte current. 
+ * 
+ * This makes the BLDC motor effectively a DC motor, and you can use it in a same way.
