*
* 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 of the current.
*
* This makes the BLDC motor effectively a DC motor, and you can use it in a same way.
