Abstract

In this paper, an analysis of the influence of the stator winding resistance on the field-weakening operation of the induction motor drive based on the Direct Rotor Flux Oriented Control (DRFOC) is presented. Two scenarions of the optimal field-weakening algorithm (with and without stator winding resistance taken into account) have been compared and verified through simulation and experiment, under different operation conditions of the DRFOC drive system with 3 [kW] induction motor.

Abstract

In this paper, an analysis of the induction motor control scheme based on the Direct Rotor Flux Oriented Control (DRFOC) for a whole speed range, including field-weakening (FW) regions is presented. Two field-weakening algorithms have been compared and verified through simulation with a 3.0 [kW] induction motor drive.
