of the motor drive. Minimizing the controllable losses has two important effects: one is to minimize the magnetic
energy that corresponds to maximizing the power factor, and the other is to minimize the coil losses that increase motor
efficiency. The problems that arise at light load operation are how to achieve the minimum time response (i.e., a minimum
speed drop) if a sudden load change takes place and how to minimize the duration of an acceleration transient after step
speed command increase [1]. To implement the above flux reduction, the motor should be fed through an inverter with
an electronic control system which uses optimization algorithms.
