Harmonic losses of single-phase induction motors under nonsinusoidal voltages

Auditing and analysis of energy consumption of an industrial site in Morocco

“…-Increasing engine losses. In fact, previous studies [26,27] that examined the impact of harmonics on single-phase asynchronous motors of 1.5 kW showed that the injection of one additional harmonic to the fundamental in addition to the fundamental one harmonic can cause an increase the motor losses of about 10%. These losses will have the effect of increasing the temperature of the motors which reduce their lifetime.…”

“…Iron loss is frequency and flux dependent and is expressed by P =P+ core CS cr {ke(oe + kh( e m +{k (So )2/ 2 +k n(su n} Pcore k + S )(t)ek1S) +kh( ±s)22 (15) core ie Rotor iron loss is quite lower than stator iron loss, because stator flux varies at the supply frequency c,e and the rotor flux varies at very lower slip frequency scoe (s< 1). In general if the supply voltage contains lower order harmonics mth switching harmonic iron loss can be considered by (16).…”

“…Analysis of machines under VVVF application is quite involved as conventional equivalent/d-q models are limited, to completely incorporate the non sinusoidal effects of supply voltage. The effects of non sinusoidal voltage supply on the induction motor behavior have been examined extensively in the literature [14][15][16][17][18]. Many modified equivalent circuits [10][11][12][13] and dynamic models [3-9] of the induction motor are proposed, taking into account the frequency-dependent nature of the motor parameters due to various phenomena like skin effect [3-6], saturation [5][6] and various losses like iron loss [7][8][9] and stray load loss [19][20].…”
