Geralmente, um motor elétrico é uma máquina que converte energia elétrica em energia mecânica e usa a energia elétrica gerada para gerar movimento rotacional e, assim, realizar o trabalho.

Embora existam muitos tipos diferentes de motores, esta página se concentra nos motores CC, que são motores conduzidos pela corrente direta (DC).Motores DCsão usados ​​em vários dispositivos e aparelhos que afetam nossas vidas.

Esta passagem vai falar sobre os seguintes do Motor DC:

(1) Introdução ao motor CA

(2) o princípio de trabalho do motor CA

(3) o amplo uso de motores CA

Introdução ao motor DC

Um motor de corrente direta (CC) é um motor que converte energia elétrica em energia mecânica. Um motor CC obtém energia elétrica da corrente direta e converte a energia em rotação mecânica.

Amotor DCusa um campo magnético gerado por uma corrente gerada, que alimenta o movimento de um rotor fixado no eixo de saída. O torque e a velocidade de saída dependem da entrada elétrica e do design do motor.

O princípio de trabalho do motor DC

Como funciona um motor DC?

O motor CC inclui dois componentes principais: o estator e a armadura. O estator é a parte fixa do motor, enquanto a armadura gira. Em ummotor DC, o estator fornece um campo magnético rotativo para acionar a armadura para girar.

A simple DC motor uses a set of fixed magnets in the stator and generates an electromagnetic field aligned with the center of the coil in a wire coil through which current passes. One or more windings of insulated wires are wound on the iron core of the motor to concentrate the magnetic field.

The winding of the insulated wire is connected to a commutator (rotary electrical switch), which applies current to the winding. The commutator allows each armature coil to be energized in turn, thereby generating a stable rotational force (called torque).

When the coils are opened and closed in sequence, a rotating magnetic field is generated, which interacts with the different magnetic fields of the fixed magnets in the stator to generate a torque, thereby rotating the torque. These key operating principles of DC motors enable them to convert electrical energy in DC power into mechanical energy through rotational motion, and then use it for the propulsion of objects.

Who invented the DC motor?

This amazing electrical device has changed our lives in many ways, but who invented themotor DC? As with all major innovations, many people have a role to play in developing similar mechanisms.

In the United States, Thomas Davenport is recognized as the inventor of the first electric motor. There is no doubt that he was the first person to obtain a patent for a usable electric motor in 1837. However, Davenport was not the first to make an electric motor with various functions. When Davenport applied for a patent, European inventors had already developed a more powerful version.

In 1834, Moritz Jacobi proposed a kind of power, its power is three times that of Davenport later patented, and Sibrandus Stratingh and Christopher Becker was the first to demonstrate the practical application of electric motors by driving a small model car in 1835.

A few years later, in 1886, Frank Julian Sprague invented the first practical DC motor. This invention invented the first electric trolley system in 1887 and invented it in 1892 The first electric lift. Various applications will reshape the face of industry and manufacturing.

The wide usage of DC motors

The term \"DC motor\" is used to refer to any rotating electrical machine that converts DC electrical energy into mechanical energy. The size and power ofDC motorsmay vary, from small motors in toys and household appliances to large mechanisms that power vehicles, traction lifts and hoists, and large mechanisms that drive steel rolling mills.

Although each type has its advantages, in a broad sense, DC motors have many uses. At home, small DC motors are used for tools, toys and various household appliances. In retail, applications for DC motors include conveyor belts and turntables, while in industrial environments, applications for large DC motors also include braking and commutation applications.

The following are some specific uses of DC motors:

Fan DC motor

DC motor for pump

Toy DC motor

DC motors for electric vehicles

Robot DC motor

Bicycle DC motor
