The electric motor for the car: the future is already close

Electric motor has long been far from the most recent place in the list of preferences of designers, including in the automotive industry. Most recently all cars were equipped with only ICE. But attempts to create alternative engines continued all the time. The most promising of them is the electric motor for the car. This article considers this type of motor and its features.

A bit of history

The inventor of an automobile electric motor is Starley. He made his discovery in 1888. At the time, electric wires were used to create tractive forces. According to the coefficient of efficiency, such a mechanism was significantly ahead of the internal combustion engines. However, at the beginning of the twentieth century, they decided to abandon such seemingly profitable units, since the problem of limited power reserve was not solved. In view of the fact that it was necessary to travel long distances, and the electric motor for the car could not provide it, it was completely replaced by internal combustion engines. For some time, only a few amateur enthusiasts have been engaged in development in this area, but in the era of rapidly developing technical progress this engine was again recalled, improved and even launched into mass production. True, so far only in small batches. Today such cars are very expensive, but the urgency and urgent need for them is increasing day by day.

Principle of operation

The electric motor for the car works on the basis of electromagnetic induction. This concept is associated with the appearance of EMF in a closed loop and with a change in the magnetic flux in it . Thus, electricity is converted into a mechanical one, due to which the vehicle is moving.

The traction motor for the car is powered by a constant current source. Batteries at the output form from 96 to 192 Volts. To generate an electromotive force, such a voltage is sufficient.

Cars with an electric motor from cars with ICE still distinguish a direct connection to the wheel, so that the handling of the vehicle is much improved. The most modern models working on alternating current can be recharged during braking, which increases their mileage to 20%.

In other respects the electric motor for the car actually differs nothing from the standard, with the engine installed. In it there is a working organ, connecting with the wheel. When electricity is supplied, the winding acts on the rotor, which starts the rotational motion due to the EMF. This is passed on to all other working bodies. The engine can be charged in many different ways, depending on the assembly.

Battery

The electric motor is charged by the battery. Because of the huge cost of batteries on the roads of such cars today is very small.

One of the types of batteries, which are the cheapest, can be called lead-acid batteries. In addition to low cost, the advantage of this type was the possibility of their recycling. Another option, nickel-metal-hybrid, costs more, but its performance is much higher.

Optimal are lithium-ion batteries, which, of course, are the most expensive. But they have the ability to keep a charge well while still being small.

Topical electrovozhki

Interesting options today are the electric motors of hybrid cars, which can be replaced by conventional, internal combustion. Of course, the price of such machines is very high. But they can be called those who have successfully solved the long-standing problem of the missing stock of progress.

From all of the above, it can be concluded that in the near future the electric motors will inevitably take their rightful place in the production of vehicles. Before many domestic motorists today, the desired goal is to create an electric motor for the car with their own hands. It turns out that this is not such an unattainable dream. For a basis any car, and even "Oka" can be taken.
