Induction machines are the most common option to generate rotary motor in industry, and at
present the use of variable speed drives with these machines is spreading in an …

When driven by an electric motor, the vibration pattern of a rotor is affected by both
mechanical and electric factors. Mechanical factors include the shaft construction, the …

This paper addresses some of the effects of running an electric motor near and in the
saturation zone of the electromagnetic hysteresis curve, namely mechanical effects such as …

The presence of harmonics in power systems is widely studied, but some of its effects are
still only partially studied and addressed in existing works. Traditionally, even the few power …

Over the last few years, there has been a sustained and unprecedented increase in the
number of electric motors driven by variable speed drives. While in some cases the project is …

The presence and effect of harmonics in power systems is widely known, but some of its
effects are still only partially studied and addressed in existing works. Traditionally, power …
