THE ENERGETIC ANALYSIS OF THE DRIVE SYSTEM WITH INDUCTION MOTOR CONSIDERING IRON LOSSES: PART 1 –SINUSOIDAL VOLTAGE SUPPLY

Autor/autori: Eng. Ileana – Anamaria MITRAN, PhD Student, Lecturer Eng. Mihaita LINCA, PhD

Rezumat: In acesta lucrare este prezentata analiza energetica a unui sistem de actionare cu motor asincron cu considerarea piederilor in fier. S-a considerat cazul in care motorul asincron este alimentat de la un sistem trifazat sinusoidal si simetric de tensiuni. Rezultatele obtinute corespund mai multor puncte statice de functionare, pentru diferite frecvente si valori ale cuplului static. In vederea obtinerii inductivitatii de magnetizare si rezistentei echivalente, s-a folosit un algoritm care presupune un calcul iterativ al acestor parametri.

Cuvinte cheie: analiza energetica, indicatori de calitate, sistem de actionare, motor asincron, pierderi în fier


Abstract: This paper presents the energetic analysis of an induction motor drive system considering the iron losses. The induction motor was powered by a symmetrical, sinusoidal three-phase voltage system. The results are obtained for several static operating points corresponding to different frequency and torque values. In order to obtain the magnetizing inductance and resistance an iterative computation algorithm was proposed.

Keywords: energetic analysis, quality indicators, drive system, induction motor, iron losses
