Abstract
The driving voltage of the motor is incremented a quantity proportional to the speed of the motor according to a proportionality factor that is adjusted to compensate the back electromotive force. A method includes open-loop voltage control of a DC motor having a certain design speed constant, through a driving signal that is determined for imparting a certain acceleration to the motor and by generating a driving voltage of an output power stage to which the winding of the motor is connected as a function of the driving signal.
