Construction of a DC GeneratorCircuit Globe

An alternator or AC generator is an electrical machine which converts mechanical energy into alternating electric energy. They are also known as synchronous generators. The working principle of an alternator or AC generator is similar to the basic working principle of a DC generator.

AC generator (alternator)construction and working

Note: A DC generator can be used as a DC motor without any constructional changes and vice versa is also possible. Thus, a DC generator or a DC motor can be broadly termed as a DC machine . These basic constructional details are also valid for the construction of a DC motor .

AC Generators and Motors Course No: E03-008 Credit: 3 PDH A. Bhatia Continuing Education and Development, Inc. . Explain the factors that determine the maximum power output of an ac generator, and the effect of these factors in rating generators. . the rotor is turned determines certain characteristics of alternator construction and operation.

Course No: E03-008 Credit: 3 PDHCED Engineering

In most practical construction of alternator, it is installed with a stationary armature winding and a rotating field unlike in the case of DC generator where the arrangement is exactly opposite. This modification is made to cope with the very high power of the order of few 100 Megawatts produced in an AC generator contrary to that of a DC .

Construction of Alternator

The rotor is a moving component of an electromagnetic system in the electric motor, electric generator, or alternator.Its rotation is due to the interaction between the windings and magnetic fields which produces a torque around the rotor’s axis.

Alternator StatorsConstruction and Design

The three phase induction motor is the most widely used electrical motor.Almost 80% of the mechanical power used by industries is provided by three phase induction motors because of its simple and rugged construction, low cost, good operating characteristics, the absence of commutator and good speed regulation. In three phase induction motor, the power is transferred from stator to rotor .

THEORY, CONSTRUCTION, AND OPERATION 1. CHAPTER 1 PRINCIPLES OF OPERATION . (dc) motor or generator, the induction motor or generator, and a number of derivatives of all these three. What is common to all the members of this fam-ily is that the basic physical process involved in their operation is the conversion . (AC) As it will be shown .

THEORY, CONSTRUCTION, AND OPERATION

For example, little electric motors, for instance, individuals who electric energy dishes blenders, tiny household equipment, and flooring cleaners get the job done very nicely on AC electrical energy, yet, large big electric motors, for instance, those which electric energy subway trains regularly execute lot better on DC electrical energy.

Difference between DC Motor and DC Generator

These components complicate the motor construction, add cost to the motor design, and require considerable maintenance. As a result, a majority of the AC machines in service, particularly small- to medium-sized motors, belong to the other general category — the induction machine.

The Basics of AC Motors | Electrical Construction

DC motor and DC generator are similar from the mechanical perspective, however from a technical stand point, both differ from each other significantly. The most significant difference between DC motor and DC generator lies in the conversion mechanism. DC motor converts electrical energy into mechanical energy whereas DC generator converts mechanical energy into an electrical energy.

What is the difference between a DC motor and a generator

These generators are packaged with an engine or turbine to be used as a motor-generator set and used in applications like naval, oil and gas extraction, mining machinery, wind power plants etc Advantages of AC Generator:

GeneratorWorking Principle and Explain about Ac and DC

AC generators are opposite from motors, because they convert mechanical energy into that of electrical. Mechanical energy is used to rotate the loops in the magnetic field, and the generated emf is a sine wave that varies in time.

The Differences Between Motors & Generators | Sciencing

An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature . [3]

AlternatorWikipedia

An alternating current generator, or AC generator, produces an alternating current, which means the voltage produced alternately reverses from positive to negative polarity, producing a corresponding change in the direction of current flow.

Construction of Induction Motor The three phase induction motor is a preferable type of motor. It is mostly used in industrial drives because it is very reasonable and vigorous, economical and reliable.

Construction of Induction MotorCircuit Globe

An induction generator is identical in construction to an induction motor. The stator windings are connected to a 3-phase power system, and the three phases create a rotating magnetic field. The induction generator’s rotor is rotated by a prime mover, which turns faster than synchronous speed.

Answering Seven Common Questions on Generator and Motor

Your permanent magnet electric motor can be used as a generator. All that needs to be done is to apply an external power source to spin the shaft of any permanent magnet electric motor and your motor becomes a generator.
