The construction of a DC generator is very similar to the construction of a DC motor. The rotor consists of an electromagnet providing the field excitation. Current to the rotor is derived from the stator or in the case of very large generators, from a separate exciter rotating on the same rotor shaft.
Introduction. Alternating current generators or alternators as they are more popularly known are work on the principle of electromagnetic induction and consist of …
The motor and the generator are almost similar from the construction point of view, as both have stator and rotor. The main difference between the two is that the Motor is an electric device which converts electrical energy into mechanical energy.
3 Phase AC Micro Brushless Generator. 1x 3 Phase AC Micro Brushless Generator. This is a 3 phase AC generator, can be connected the two lines can light up …
As a result, the ac generator is the most important means of producing electrical power. Ac generators, Ac generators, generally called alternators, vary greatly in size depending upon the load to which they supply power.

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.
AC Motor/Generator theory Most of the information I used to design this motor came from this page . I placed six magnets on the rotor with alternating poles and placed 6 …
Originally Answered: What is the difference between AC/DC motor & generator? Construction per se, both have stator and rotor and may look identical. The main difference is that AC/DC motor (also called electric motors ) converts electrical energy into mechanical energy whereas generator does the …
THEORY, CONSTRUCTION, AND OPERATION 1. CHAPTER 1 PRINCIPLES OF OPERATION OF SYNCHRONOUS MACHINES The synchronous electrical generator (also called alternator) belongs to the family of electric rotating machines. Other members of the family are the direct-current (dc) motor or generator, the induction motor or generator, and a number of derivatives of all these three. What is …
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.
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 .
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.
A hand-cranked generator can be used to generate voltage to turn a motor. This is an example of energy conversion from mechanical to electrical energy and then back to mechanical energy. This is an example of energy conversion from mechanical to electrical energy and then back to mechanical energy.
2009-12-02· Three-phase AC induction motors are commonly used in industrial applications. This type of motor has three main parts, rotor, stator, and enclosure. The stator and rotor do This type of motor has three main parts, rotor, stator, and enclosure.
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.
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 generator. To accommodate such high power the ...
Definition: AC Generator is an electrical machine which converts mechanical energy into electrical energy. The input supply of AC Generator is mechanical energy which is supplied through some prime-mover and the output is alternating energy in the form of alternating voltage & current.
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. As the rotor windings cut through the rotating field, current is induced in them. This induced ...
Difference between a DC motor and a generator in terms of EMF: In terms of EMF, in DC motor EMF is consumed by the motor coil and utilized to rotate the axle. On the other hand, in DC generator EMF developed across coil is transfered to a load or a battery and consumed by them. In both d.c motor & d
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. Much like a DC generator, an AC generator requires a coil to cut across the force lines of a magnetic field. This coil is attached to two slip rings, which ...

In construction, a dc generator is similar to a motor, or even an ac generator, with the addition that slip rings are replaced by split rings. Its three main parts are: …
The AC generator head is direct coupled to the Tecumseh 8 HP motor, and has a belt driven 12 volt alternator mounted to our Horizontal generator bracket which is attached to the motor. To get the full rated output of 6,000 W peak from the generator head, this particular motor is under powered. To develop the full rated output power from this head, the engine should really be a 10 HP model like ...
It is almost same for any given synchronous motor or a generator. It is made up of number of stampings, which are slotted to receive the windings. Lets see the construction of a three phase stator. The three phase windings are placed on the slots of laminated core and these windings are electrically spaced 120 degrees apart. These windings are connected as either star or delta depending upon ...
Motor Generator sets use several methods of coupling the drive motor to the generator. The simplest and least expensive method is belt coupled converters that use drive belts and pulleys to not only transfer the energy from motor to generator, but also change the frequency by pulley ratio.
A commutator is a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit.
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.
