NTRODUCTION:

The predominant type of prime movers for DP propulsion plant is Electric Drive.


The most commonly used motor drives are:


DC converters, or SCR for DC motors.

Cyclo converters for AC motors ,normally for Synchronous motors .

Current Source Inverters (CSI) for Ac motors (Synchronous Motors )

Voltage Source Inverters ,(VSI)for AC motors ,i.e. asynchronous, ....etc

Abstract-
 As the cost of energy increases it is increasingly more important to remove inefficient motors from operation.
 It describes the results of a very-low-cost & accurate method for determining the motor efficiency without the need for removing the motor & without the need for measuring the output power or torque.
 Test results indicate that the novel method has an accuracy of over 99%.

POTENTIAL OF PIEZO ELECTRIC ECOFLOOR FOR GENERATION OF ELECTRIC POWER


The need to generate electricity is the demand for today’s life because of the fact that even if the planet doubles the amount of solar and wind power available, there would still be a shortage of clean electricity. Comparison of different forms of commercial power generation by use of the fuel cycle methods developed in European studies shows that the health burdens are extreme in areas where power stations (base ....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 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.
