Impact of magnetic saturation on the steady-state operation of the controlled induction motor
Petar Ljušev, Drago Dolinar, Gorazd Štumberger, 2003, original scientific article

Abstract: The paper presents a method for determination of the steady-state torque characteristics of the induction motor in the case of rotor field-oriented control (RFOC) with nonlinear magnetizing characteristic of the iron core included. The torque characteristics are determined for the constant stator current and the constant d-axis stator current. The characteristics obtained at a constant stator current are used to maximize the torque capability of the RFOC induction motor. The aim of the presented work is to obtain required steady-state torque with minimal stator current. Experiments show that the proposed selection of a magnetizing reference is promising.
Keywords: induction motor, torque characteristics, magentic saturation
