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
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

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

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

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
