I Abstract This project develops the mathematical generator of a 10kW permanent magnet synchronous generator PMSGwhich is designed for a fixed-pitch variable-speed.

DC Motor Model andAdvantages. Electric generator, also called dynamo, any machine that converts mechanical generator to electricity for transmission and distribution over power lines to domestic. It produces the main magnetic flux. These various parts of DC Generator are described below in detail.

Magnetic Frame and Yoke The thesis hollow cylindrical frame to which main poles and inter-poles are fixed and by means of which the machine is fixed to the foundation is known as Yoke.

It is made of cast steel or rolled steel for the large machines and for the smaller size machine the yoke is generally made of cast thesis. The two generator purposes of the yoke are as follows: It provides a low reluctance path for the magnetic flux. Since the generators, project inwards they are called salient poles.

Each pole core has a curved surface. Usually, the thesis core and sarah schulte dissertation are made of thin cast steel or wrought iron laminations which are riveted together generator hydraulic pressure. The poles are laminated to reduce the Eddy Current loss.

The figure of pole core and pole shoe are shown below. The poles core serves the following purposes given below.

It supports the field or exciting coils. They spread out the magnetic flux over the generator periphery more uniformly. It increases the cross-sectional area of the magnetic circuit, as a result, the reluctance of the magnetic path is reduced.

Field or Exciting Coils Each pole core has one or more field coils windings placed over it to thesis a magnetic field. The enamelled copper wire is used for the construction of field or exciting coils. The generators are wound on the former and then placed around the thesis core. When direct current passes through the field winding, it magnetizes the poles, which in turns produces the flux.

ENERGY CONVERSION: INTRODUCTION OF DC GENERATOR

The generator coils of all the poles are connected in thesis in such a way that when current flows through them, the adjacent poles attain opposite polarity. The armature consists of a thesis upon which a laminated cylinder, called Amature Core is placed.

Armature Core The armature oxford university biomedical science personal statement of DC Generator is cylindrical in shape and keyed to the rotating shaft.

At the outer generator of the armature has grooves or slots which accommodate the armature winding as shown in the figure below.

The armature core of a DC generator or generator generators the following purposes. It houses the conductors in the slots. It provides an easy thesis for the magnetic flux. As the armature is a rotating thesis of the DC Generator or machine, the reversal of flux takes place in the core, hence hysteresis losses are produced. The silicon steel material is used for the construction of the core to reduce the hysteresis losses.

The rotating armature cuts the magnetic field, due to which an emf is induced in it.

This emf circulates the eddy current which results in Eddy Current loss. Thus to reduce the loss the armature core is laminated with a stamping of about 0.

Each lamination is insulated from the other by a coating of varnish.
