How Electric Motors Are Used in Automobiles


Today, automobiles are the primary means of transportation for families around the world. In the United States alone, there are 1.4 billion passenger cars in circulation. Of these, one-fourth are foreign-made vehicles. Each year, approximately 70 million new passenger cars are produced. Manufacturers have successfully split the market into multiple segments, allowing them to introduce new designs more frequently.

Internal combustion engine

The internal combustion engine is a powerful source of power for automobiles. It has several advantages over an electric motor, including portability. Internal combustion engines are also commonly used in hybrid cars to recharge their batteries. However, they come with a variety of disadvantages. These drawbacks include noise, waste part emissions, and pollution. Some are even so loud that hearing protection is required in some areas. For these reasons, the internal combustion engine in automobiles is often not a good option for many people. An electric motor can be a viable replacement for this powerful, yet inefficient source of power.

Assembly line

As the world moved toward personal vehicles, assembly line methods became an essential factor in making them. Although Henry Ford is often credited with creating this revolutionary method, his invention actually came from his rival, Ransom Olds. He saw the benefits of this process and decided to introduce it to the Ford Motor Company. The assembly line would become a standard production method, increasing Ford’s production by 485 percent in a single year.

An assembly line allows for the rapid and accurate assembly of automobiles. Unlike other processes, the assembly line can produce large numbers of goods quickly and inexpensively. This reduces the overall production cost, resulting in higher profits. As a result, the assembly line can produce a single car in just under a half-hour.

Gasoline engine

A gas engine in an automobile is used to power a vehicle’s drivetrain. However, the energy contained in gas is lost at various stages throughout the engine’s life. For example, only 15 percent of the energy in gasoline is actually used to move the car. This means that the remaining 85 cents is wasted in various ways. To save energy, automobile manufacturers are trying to make their engines more efficient.

The first gas-fueled automobile was patented in 1886 by Karl Benz. Later, Daimler developed a four-stroke engine with mushroom-shaped valves and two V-slant cylinders. The first four-cylinder automobile was built by Wilhelm Maybach. Many of these early engine designers went on to become major automobile manufacturers.

Electric motor

In automobiles, the electric motor is used to generate torque to turn a load. It converts electrical energy by applying a force between two magnetic fields, one externally excited and the other internally excited. The two types of motors can be classified as synchronous or asynchronous. A synchronous motor generates torque during acceleration and deceleration, while an asynchronous motor produces torque during acceleration.

A typical automobile electric motor contains a rotor and a stator, which spin in opposite directions. The rotor can spin forwards or backwards, or it can stop and change direction. In addition, the rotor can speed up or slow down.
