LINEAR MOTORS AND IT’S USE IN MAGLEV TRAIN
INTRODUCTION
A LINEAR MOTOR OR LINEAR INDUCTION MOTOR IS AN AC ELECTRIC MOTOR THAT HAS ITS STATOR UNROLLED SO THAT INSTEAD OF PRODUCING A TORQUE(ROTATION) IT PRODUCES A LINEAR FORCE ALONG ITS LENGTH.
HOW LINEAR MOTORS WORK
SPLIT A ROTORY MOTOR RADIALLY ALONG ITS AXIS OF ROTATION
FLATTEN IT OUT:
RESULT: A FLAT LINEAR MOTOR THAT PRODUCES A DIRECT LINEAR FORCE INSTEAD OF TORQUE.
ANALYSIS METHO ....etc

A Robust Sensorless Direct Torque Control of Induction Motor Based on MRAS and Extended Kalman Filter
Presented By:
Mustapha MESSAOUDI, Habib KRAIEM, Mouna BEN HAMED, Lassaad SBITA and Mohamed Naceur ABDELKRIM

Abstract
In this paper, the classical Direct Torque Control (DTC) of Induction Motor (IM) using an open loop pure integration suffers from the well-known problems of integration especially in the low speed operation range is detailed. To tackle this problem, the IM variables and parameters estimation is pe ....etc

Power Factor Correction of Linear and Non-linear Loads Employing a Single Phase Active Power Filter Based on a Full-Bridge Current Source Inverter Controlled Through the Sensor of the AC Mains Current
Abstract:
In the last years the number of non-linear loads has been increasing rapidly. This non-linear load had drawn a current form the AC Mains with harmonic components, leading to low power factor, low efficiency, interference by the EMI, among others. A classic solution is the use of passive filters, which ....etc

LINEAR INDUCTION MOTOR



INTRODUCTION


In a sector motor when the sector is laid out flat and a flat
squirrel-cage winding is brought near to it ,we get a Linear
Induction Motor.In practice,instead of a flat squirrel-cage
winding ,an aluminium or copper or iron plate is used as a
‘Rotor’.The flat stator produces a flux that moves in a straight
line from its one end to the other at a linear synchronous speed
given by:
Vs = 2Wf
As the flux m ....etc

ABSTRACT
Indirect field orientation (IFO) induction machine drives are increasingly employed in industrial drivesystems, but the drive performance is often degrades. Motor works on best performance at certain voltageand frequency for certain loads. In this paper artificial neural network is used to predict the operatingvoltage and frequency when the load torque and speed going changed so motor efficiency is increased.Simulation and experimental results are shown to validate the scheme.
