The electric motor is intended to be a part to be used in any vehicle, and the reason for this is the important advantages it presents compared to what can be the gasoline or diesel propellant of a conventional vehicle. However, this type of electrified motor has several fundamentals and behaviors that they distance him considerably of the old generation.
The advantages of the electric motor are considerable
Since they revolutionized the market with their appearance, hybrid and electric cars have become more and more normalized. Its price is democratizing and cities offer a higher number of charging stations. But what do their electric motors have to do with it? Or what is the same; Beyond being more sustainable, what other advantages do we have with them?
First of all, we have to emphasize that this type of propellant is a type of rotating machine or device that converts electrical energy into mechanical, this by means of electromagnetic interactions. Much simpler than conventional ones, they are able to deliver the same power with less effort.
As we will see below, the good work of these propellers also translates into an efficiency that increases considerably. up to over 90% in many cases, since heat losses are considerably reduced by reducing the friction of moving parts. But there are others that make the electric motor have multiple advantages over gasoline or diesel combustion.
All your plus points
Something also to value is that these can be reversible, that is; act as generators and transform mechanical energy into electrical energy. There are even those that can produce both types of energy at the same time, as in the case of some hybrid cars.
In those, as we say, the electrified device can be equipped and combined with other parts that are then the car can work in a different way than another. Following this line, we also have them in that, by using fewer pieces, they suffer a much less wear over time, as well as having less maintenance.
About them, we have to take into account aspects that will tell us, later, if it is possible to make these cars have more efficient levels. This translates into lower energy consumption, for example.
- Pollution. This is where electric motors win and why they are so sought after. They do not generate emissions compared to the innumerable types of polluting elements that are emitted by those that are powered by gasoline, such as CO2, or all the greenhouse gases produced by the combustion of fossil fuels.
- energy expenditure. With clear advantages of the electric motor, the alternative to electricity is seen as a more than obvious saving compared to gasoline.
- Noise. Very favorable for these engines, they do not have any type of internal process, so the noise decreases to zero, unlike conventional ones, which cause a large amount of noise pollution in large urban areas.
- Reduction of parts and maintenance. Unlike conventional ones, these do not need maintenance as they do not have moving parts subject to friction or high temperatures. In addition, although the electric car as we know it today is something very recent, the reality is that it is a very proven technology and that it was invented even before the combustion engine.
- Immediate response. There is no burning or explosion in the electric motor. It works with a set of coils and works with inversion of magnetic fields. This, for its part, makes the response when accelerating much faster and more controlled.
- more efficient. As such, and as a point that becomes important towards its lower cost of recharging, it is that these propellants are much more energy efficient than combustion engines; use between 0.1 and 0.23 kW/h per kilometer
- regenerative braking. During car braking, an electric motor works as a generator. The energy output produced after converting is used to recharge the batteries. This means that the vehicle returns energy to the system.
A change more than justified
As we have seen, based on all these seven advantages that we have with this type of electric motor, they make themselves look like machines essentially better than those that can be combustion to generate movement.
For its part, and taking into account the growing ecological awareness of modern societies, we can say that, if we are willing to make small sacrifices in exchange for the substantial improvements that the electric vehicle promises, it is possible that the time has come to carry out its complete transition. The change would be fully justified.
