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
In the present scenario, bomb blasts are rampant all around the world. Bombs went of in buses and underground stations, killed many and left many injured. Bomb blasts can not be predicted before hand. This paper is all about the technology which predicts the suicide bombers and explosion of weapons through IMAGING FOR CONCLEAD WEAPON DETECTION, the sensor improvements, how the imaging takes place and the challenges. And we also describe techniqu ....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

Concealed weapon detection (CWD) is an increasingly important topic in the general area of law and enforcement and it appears to be a critical technology for dealing with terrorism, which appears to be the most significant law enforcement problem for the next decade.
Since no single sensor technology can provide acceptable performance in CWD applications, image fusion has been identified as a key technology to achieve improved CWD procedures.
Existing image sensing mechanisms include thermal/infrared (IR), millimeter wave, and visual.
In o ....etc

Magnet (PM), Pulse Width Modulation (PWM)
Abstract
A new concept in Urban Maglev transportation design is in the testing phase. The vehicle uses
permanent magnets (PM) for both the electro-dynamic suspension (EDS) and linear synchronous
motor (LSM) propulsion. Because of the 3D coupled non-linear velocity-dependent magnetic
levitation, the LSM must provide stabilizing forces to the vehicle. To do this, Vector Control is used

ANALYSIS OF PERFORMANCE OF SINGLE- PHASE RELUCTANCE LINEAR MOTOR
Abstract
This article describes the design and principle of operation, and the electromechanical phenomena of a single phase induction motor.The motor has a primary part which is moving and a stationary secondary part which does not have any winding. AC or DC supply can be used to operate the motor. A capacitor connected in series with the coil must be used when the motor is fed from the AC source. Whereas, a controlled switch connected to the primary circuit mus ....etc

ABSTRACT
High Power Electromagnetic Pulse generation techniques and High Power
Microwave technology have matured to the point where practical E-bombs (Electromagnetic
bombs) are becoming technically feasible, with new applications in both Strategic
and Tactical Information Warfare. The development of conventional E-bomb devices
allows their use in non-nuclear conf ....etc

Abstract
An alternating current (AC) electric motor that has had its stator unrolled so that instead of producing a torque (rotation) it produces a linear force along its length is called a linear motor or linear induction motor. The most common mode of operation is as a Lorentz-type actuator, in which the applied force is linearly proportional to the current and the magnetic field.

Many designs have been put forward for linear motors, falling into two major categories, low-acceleration and high-acceleration linear motors. Low-ac ....etc
