Vector control is becoming the industrial standard for induction motor control. The vector control technique decouples the two components of stator current space vector: one providing the control of flux and the other providing the control of torque. The two components are defined in the synchronously rotating reference frame. With the help of this control technique the induction motor can repl...

Induction motors are widely used in the industry due to its relative low cost, low maintenance and high reliability. The development of the computer and electronic industry, as well as design of new control methods, has opened the door to control induction motors. In order to control the induction motors, scalar and vector control methods are used. Vector methods have faster response and more p...

Introduction. Wound-rotor induction motors are less common compared squirrel-cage motors. However, they occupy a significant share among electric drives with difficult starting conditions. Their advantage is obtaining high electromagnetic torque at lower values of currents. Problem. Due to the possibility including different devices in rotor circuit, it possible shape characteristics according ...

In recent years, synchronous reluctance motor (SynRM) has attracted the attention of researchers and well-known companies have been involved in designing manufacturing electric motors due to its simplicity (no need for a rotor cage permanent magnet), similarity production line analogous that induction motor, low cost also, compared better performance, if optimally designed. Saliency ratio, defi...

A direct-on-line synchronous reluctance motor (DOLSynRM) with a rotor topology defined by the natural flux line curve approach is studied as an alternative to induction (IM) using 1.5 kW, 50 Hz example. If IM stator used, direct squirrel cage replacement equipped damper winding might not guarantee sufficient starting performance. To ensure strong enough capability, was modified in design. The p...

Three-phase induction motors are widely used in electric traction systems. Impacts of the traction vehicle equipped by three-phase induction motors on power quality are much different from the impacts of vehicles with DC traction motors. In this paper, the effects of the traction vehicle operation with threephase induction motors on power quality in 110 kV transmission network are investigated....

pulse-width modulated (pwm) adjustable frequency drives (afds) are extensively used in industries for control of induction motors. it has led to significant advantages in terms of the performance, size, and efficiency but the output voltage waveform no longer remains sinusoidal. hence, overshoots, high rate of rise, harmonics and transients are observed in the voltage wave. they increase voltag...

this paper presents an indirect adaptive system based on neuro-fuzzy approximators for the speed control of induction motors. the uncertainty including parametric variations, the external load disturbance and unmodeled dynamics is estimated and compensated by designing neuro-fuzzy systems. the contribution of this paper is presenting a stability analysis for neuro-fuzzy speed control of inducti...
