Do you know the types of electric motors for cars that exist?

Published

As its name indicates, the electric motors of this type of new generation car are formed within an electrified system that is what makes and allows the rest to function. However, something that is paid great attention is that these can be found (and used) with different types in one car or another. However, What are their differences about and how many types are there?

Green cars are the future of clean, emission-free mobility. A type of vehicle that, beyond being the great attention of the present and of the times to come, are also very characteristic because they do not look the same way that we are used to with combustion engines. Everything is seen from his own heart, the motor.

Cars and the electrification of their engines

Because if we look at the mechanics itself, inside we can see that its operation is much simpler than that of a heat engine. Contrary to engines that run on fuel in which the energy is given by explosion, in these the movement occurs thanks to electromagnetic interactions.

That could be, first of all, the great differentiation that we can have between these types of electric motors and those of combustion. However, among them it is possible that there are also notable distinctions, especially when it comes to its format, and that will then affect the vehicle in one way or another.

Thus, as we say, the basic operation of an electric motor is based on electromagnetic rotation. This consists of the use of two magnets that either reject or attract each other, depending on the alignment of their poles. That orientation will be the one that generates a forward or backward movement. With very good reliability and performance as the main fundamentals, electric motors use electricity to create magnetic fields. That is when we can distinguish several types of what these electric motors are.

Electric car motors how are they

What types are there

In this case, we see it from the fact that these electric motors are propellants that do not need internal combustion to provide energy, but rather it comes through the force produced by the stator and rotor. These systems can work both through batteries and connected to an electrical network. Within electric motors we can find a main classification of alternating current for automotive use that distinguishes them into two types.

  • Synchronous. It is characterized because the rotor rotates at the same speed as the stator’s magnetic field, which makes it move. The north face of the rotor magnet will follow the south face of the stator. The rotor uses a series of magnets, usually neodymium. Their rotational speed is constant and they can function as motors or generators.
  • Asynchronous. The asynchronous motor is an alternating current electric motor in which the angular speed of the rotor is less than the rotational speed of the magnetic field. generated by the stator windings, hence the asynchronous.

The end goal is clear, reduce the cost, use lighter materials in the construction of engines, optimize performance based on use or learn to better manage the use of batteries, which is what most manufacturers are doing, including Tesla.

How it works and what are they based on

Thus, and through the two types of motors, what they do is convert battery energy into mechanical energy. Its operation is based on the basic principle of magnetism: charges of the same sign repel and those of the opposite sign attract. As current passes through the stator, a magnetic charge is created that interacts with the poles of the electromagnet built into the rotor, which is the main shaft, and causes it to rotate.

The polarity of the charge in the coils changes according to the direction in which the electric current flows, by changing the direction every half turn the rotor remains in continuous movement. East movement is transferred to the wheels and varies in speed according to the frequency of the current.

These are the most realistic artificial voices of the moment

Published

on

We are used to hearing computer generated voices on different devices. In smart assistants, in gadgets, in ebook readers, on websites…. these voices are more and more present, but they continue to feel artificial, something that will cease to be so in a few years.

The fact is that there are already artificial intelligence engines capable of creating voice systems that are extremely natural, and today I will show you where to listen to them.

Is about vocalora.com, a web project that uses one of the world’s most sophisticated speech engines to simulate the voice of 5 different English accents, using 18 different voices in the process.

We can paste a text (in English) and select the desired voice from all the available ones. Once done, we will click on the Read Text button that appears on the right. If during the reading process we put a different voice, both will be heard at the same time.

Both male and female voices and children’s voices are available, and the result is so impressive that it is difficult to understand how our vacuum cleaner continues to speak with an 80’s movie voice.

We can try vocalora for free, but if we need readings of several hours, we will have to go through the premium subscription (about 20 dollars per month).

At the moment there are no projects with the same quality in Spanish, at least not on a website of these characteristics, available to the general public, although it is a sector that is advancing a lot, so it will not be long before we have something like this soon in our language.

Mobile GeForce RTX 3070 Ti is faster than Titan RTX and nearly as fast as Radeon RX 6800

On January 5 at CES 2022, Nvidia introduced new graphics cards, including the mobile GeForce RTX 3080 Ti and GeForce RTX 3070 Ti. During the announcement, Nvidia revealed that the top model is faster than the desktop GeForce Titan RTX, but what about the GeForce RTX 3070 Ti? Now this 3D accelerator has been tested in Geekbench (as part of the MSI Vector GP66 laptop), and in the OpenCL test, it showed a result exactly on the level of Titan RTX. What’s more, the desktop Radeon RX 6800 isn’t far ahead.

Given that GeForce RTX 3070 Ti laptops start at $1,500, this is a very good deal for both gamers and those looking to purchase a laptop for professional use. Mobile PCs with the GeForce RTX 3080 Ti are already much more expensive, starting at $2,500. Interestingly, the Radeon RX 6800 retails for around the same $1,500, so users will have the choice of buying just the graphics card for the same amount, or an entire laptop with graphics performance nearly equivalent to that graphics card.

Recall that the mobile GeForce RTX 3070 Ti is built on a GA104 GPU with 5888 CUDA cores with a frequency of 1035-1485 MHz. The GPU is connected to 8GB of 14GHz GDDR6 memory via a 256-bit bus.

The Samsung Galaxy A53 looks no different from the Galaxy A52. Published a live photo of the back of the smartphone

Live photos of the rear panel of the promising Galaxy A53 smartphone, which replaces the current Galaxy A52, have been published on the Web. Given that modern smartphones differ only in camera blocks, the Galaxy A53 will almost repeat the Galaxy A52: they have the same camera blocks.

On the shelf of the Galaxy A52 and A53 it will be difficult to distinguish, but in technical terms, the novelty will not go far from the current model. For example, sensors with a resolution of 64, 12, 5 and 5 megapixels, according to preliminary data, will remain in the main camera. What will change then? Galaxy A53 is credited with a more powerful SoC (Snapdragon 778G or Exynos 1200), and the battery capacity will also increase to 5000 mAh. The 6.5-inch AMOLED screen will remain, but the frame rate will increase to 120 Hz.

Galaxy A53 will most likely be released in March. And in February, the premiere of more affordable models is expected – Galaxy A13 and Galaxy A33.
