Since our motors are very efficient, this is also true when operated as generators. The basic calculations between speed and voltage as well as current and torque are very simple.

## Different Types of Electric Motors

A Direct Current Moto r, DC is named according to the connection of the field winding with the armature. Mainly there are two types of DC Motors. The self-excited motors are further classified as Shunt wound or shunt motor, Series wound or series motor and Compound wound or compound motor. The dc motor converts electrical power into mechanical power.

The construction of the dc motor and generator are the same. But the dc motor has a wide range of speed and good speed regulation in electric traction. The working principle of the dc motor is based on the principle that the current-carrying conductor is placed in the magnetic field and a mechanical force is experienced by it. The DC motor is generally used in the location that requires a protective enclosure, for example, drip-proof, the fireproof, etc. The detailed description of the various types of motor is given below.

As the name signifies, the field coils or field windings are energised by a separate DC source as shown in the circuit diagram shown below:. As the name implies self-excited, hence, in this type of motor, the current in the windings is supplied by the machine or motor itself. Self-excited DC Motor is further divided into shunt wound, and series wound motor.

They are explained below in detail. This is the most common types of DC Motor. Here the field winding is connected in parallel with the armature as shown in the figure below:.

I is the input line current Ia is the armature current Ish is the shunt field current. VI a is the electrical power supplied to the armature of the motor. In the series motor, the field winding is connected in series with the armature winding. The connection diagram is shown below:. The connection diagram of the compound motor is shown below:.

In a cumulative compound motor the flux produced by both the windings is in the same direction, i. In differential compound motor, the flux produced by the series field windings is opposite to the flux produced by the shunt field winding, i.

The positive and negative sign indicates that the direction of the flux produced in the field windings. You left out the long-shunt and short shunt compound motor connection. Thank you for such easy explanation through diagrams. I have clearly understood the equations as well. Your email address will not be published.

## The Differences Between Motors & Generators

As we know, an electric motor plays a vital role in every sector of the industry, and also in a wide range of applications. There are a variety of types of electric motors are available in the market. The selection of these motors can be done based on the operation and voltage and applications. The main function of field winding is to produce the fixed magnetic field, whereas the armature winding looks like a conductor which is arranged within the magnetic field. Because of the magnetic field, the armature winding uses energy to generate an adequate torque to make the motor shaft turn. Currently, the classification of the DC motor can be done based on the winding connections, which means how the two coils in the motor are connected with each other.

and direct current (DC) theory, circuits, motors, and generators; AC power and for understanding the basic operation of various types of DOE nuclear facility.

## Commutator (electric)

A Direct Current Moto r, DC is named according to the connection of the field winding with the armature. Mainly there are two types of DC Motors. The self-excited motors are further classified as Shunt wound or shunt motor, Series wound or series motor and Compound wound or compound motor. The dc motor converts electrical power into mechanical power.

Motors and generators are electromagnetic devices. They have current-carrying loops that rotate in magnetic fields. This rapidly changing magnetic field produces electromotive forces, called emfs or voltages. Electric motors and generators are the opposite of each other. Electric motors convert electrical energy into mechanical energy, while electric generators convert mechanical energy into electrical energy.

General Information: Emergency Contact: Email: contactus powerplus. Is your business in need of an AC generator or a DC backup generator? Can you tell the difference between the types of generators available on the market and which one best fits your needs? Here is what you need to know so you can invest in the right generator for your business. In order to determine which generator you need, you should understand a few things first. For example, how do they work? What are the differences between AC and DC?

Even though annealed at the mill, fully processed material may require further stress relief anneal after stamping. The stresses introduced during punching degrade the material properties around the edges of the lamination, and must be removed to obtain maximum performance. Because of its lower electrical conductivity, aluminum wire requires a 1. Insulation Modern magnet wire typically uses one to four layers of polymer film insulation, often of two different compositions, to provide a tough, continuous insulating layer.

Может.  - Сьюзан пожала плечами, демонстрируя равнодушие. - Мы с ним какое-то время переписывались, - как бы невзначай сказал Хейл.  - С Танкадо. Ты знала об. Сьюзан посмотрела на него, стараясь не показать свое изумление.

- Не выпускай ее из приемной. Бринкерхофф кивнул и двинулся следом за Мидж. Фонтейн вздохнул и обхватил голову руками. Взгляд его черных глаз стал тяжелым и неподвижным.

Стратмор молчал. Положение оказалось куда серьезнее, чем предполагала Сьюзан. Самое шокирующее обстоятельство заключалось в том, что Танкадо дал ситуации зайти слишком .
