Abstract: The torque characteristic of an electrically driven brushless motor may be optimized by driving the phase windings of the motor with predefined, digitized and stored current or voltage profiles. Appropriate sequences of digital samples of the predefined driving profile are sequentially read from a nonvolatile memory where they are permanently stored to drive, through a DAC, the relative winding of the motor in synchronism with a signal representative of the rotor position.
