Modeling of Armature Controlled D.C Motor

INTRODUCTION
What is DC Motor?

A direct current (DC) motor is a fairly simple electric motor that uses electricity and a magnetic field to produce torque, which turns the motor.
A dc motor is used to convert electrical energy into mechanical energy for driving loads.

PRINCIPLE OF OPERATION

The operation of a dc motor is based on electromagnetism.

FLUX ESTIMATORS FOR SPEED-SENSORLESS
INDUCTION MOTOR DRIVES



Abstract

This thesis deals with flux estimators for speed-sensorless induction motor drives. To enhance
the stability and the performance of state-of-the-art sensorless drives, new flux estimator
designs based on the standard motor model are proposed. Theoretical and experimental
research methods are both used. The dynamics and stability of flux estimators
are analyzed using linearized models, and the effects of parameter errors are investig ....etc

Abstract
A significant percentage of the flux used in submerged are welding gets converted into very fine particles particles
termed as flux dust due to transportation and handling. If these very fine particles are not removed fromt he flux before
welding, it may results ....etc

Abstract:
The field oriented control emerged as an important approach for the control of AC machines, and continues to be explored and developed in the literature. The estimation of the rotor flux from the measurable variables was the only method used to implement the vector control of the induction machine. To replace the estimator based on the mathematical model of the system, which can lead to unintended errors due to uncertainties on the model and on the measures we use an appropriate observer.
