Reflections on the electric motors of the future

The design, location and integration of electric motors in vehicles is rapidly changing to achieve maximum efficiency without losing power and occupying as little space as possible.

Around 200 companies are engaged in the manufacture of traction motors for electric vehicles. By 2025 the electric vehicle business could move about $ 500 billion, of which $ 25 billion would be motoring. While battery technology seems to be lithium-depleted also for future motors you can check on this website, with some variations in the rest of the chemical components, the industry of electric traction motors is much more complex.

In some cases it is the engine manufacturers who perform the integration in the chassis, the adjustment with the rest of the components of the vehicle and the electronic suitability. In others, the manufacturers themselves carry out this operation. This feature opens up a range of possibilities that can significantly affect the final price of the traction system. Another completely different case is the specific motors for motorcycles and electric bicycles. The price of these vehicles has an important impact on their engines and components such as neodymium and rare earths.

Most pure electric vehicles still place the engine in the front bonnet, although the trend begins to change by bringing them closer to the wheels, so it is not uncommon to find motors on the axles and even on the wheels, releasing much space in the Interior of the vehicle while lowering the center of gravity and increasing power and torque. In the case of in-wheel motors, the disadvantage may be in the instabilities that can be caused by non-suspended masses whose movements are not damped by the suspension.

It is also common to find electric motors integrated in the transmission, especially in the case of hybrids where they are more efficient to obtain increase the energy when working together with the combustion engine. In some cases the electric motor is located near the combustion engine or the exhaust pipe so it is necessary to tolerate very high temperatures.

The requirements that these engines must meet are above all high energy efficiency and profitability. They require peak powers that sometimes reach twice the nominal and a very high torque that is maintained throughout the power range.

Samsung Galaxy S7, Analysis: is It as Good As The Edge Version?

After analysing the Samsung Galaxy S7 edge in depth, today it is the turn to the flat version, ie the Samsung Galaxy S7. As we could see in its presentation, this model has a complete size, so do not compete directly in this aspect, as it did last year with the Samsung Galaxy S6 and S6 edge.In essence, this Samsung Galaxy S7 is the same phone as the Galaxy S7 edge, saving the differences in size and type of screen. Here we have no curved edges, but a standard flat screen. Come on, the one of all the life. Then, we will tell you everything you have to know about the latest Samsung smartphone, do not miss it!

Samsung Galaxy S7, features and technical specifications
On the Samsung Galaxy S7, the screen stays at 5.1 inches, a size for many ideal not to be too large, not too small. The South Korean firm has been able to take advantage of the space well – 72% of the front is screen -, as we are accustomed, so the terminal barely exceeds 14 centimetres high. Of course, the panel also features Super AMOLED technology and Quad HD resolution, which in this case translates to no less than 577 pixels per inch.

Samsung Galaxy S7, Analysis is It as Good As The Edge Version

Of course, this is a premium terminal in every way, and that includes finishes and building materials, glass and glass and aluminium, so it offers the same quality as your brother with curved edges. Therefore, the sensations on the hand are very similar, although evidently, this model is somewhat more comfortable in the use, to be more compact.If we go inside, the chipset that gives life is the Samsung Exynos 8 Octa 8890, ie a powerful octa-core accompanied by the graphics unit Mali-T880 MP12 at 650 MHz. It is noteworthy that there is also a model with The Qualcomm Snapdragon 820, but the Exynos is the one that we have analysed and the main model that is going to be sold worldwide. Next, to this chip, we have 4 GB of RAM with the latest technology in mobile, LPDDR4, and UFS 2.0 memory of 32 or 64 GB of internal storage, with the possibility of expanding it via microSD.

In the section on photography, we see an improved main camera compared to the previous generation Samsung Galaxy, thanks to a sensor of 12 megapixels and better aperture focal (f / 1.7). It incorporates Dual Pixel Sensor technology, optical image stabiliser, and dual LED flash. As for the front camera, we have a 5-megapixel sensor, with the same aperture as your rear camera.

The rest of the features are summarized in the latest software, Android 6.0.1 Marshmallow with TouchWiz as main actor, all kinds of connectivity, but still missing the FM radio as is customary in Samsung, and there is still no trace of the USB type- C, and a battery of 3000 mAh, 600 less than in the Galaxy S6 edge. We must also take into account extras such as water and dust resistance (IP68), the fingerprint reader or Always on Display, among other things.

Price and availability
The official price of the Samsung Galaxy S7 is 719 euros, but in stores such as Amazon or eBay can already be achieved for less than 700 euros and even for less than 600 import.If you want an Android phone in less than 10,000 Indian rupees then I’d recommend you Xiaomi Redmi 3.


The Samsung Galaxy S7 is the perfect phone if you are looking for something compact and above all, a top of the range with all the letters. Here we lose the curves of the S7 edge, but for the rest are two drops of water. So if you like the S7 edge but you do not convince that feature, or want a smaller phone, this is the perfect alternative. And on top of that, it will not cost you that much.

Positive points

  • Camera: Without doubt one of the strongest points of this terminal. The whole photographic set, including rear camera, front and software, make it one of the best phones in this field, if not the best.
  • Performance: Simply spectacular, and it is that everything moves with an incredible ease.
  • Screen: The image quality is the best in the market, and in addition, the size is ideal for many users.

Bad points

  • FM Radio: A phone that has everything … minus the FM radio. Is it so hard for Samsung to incorporate it?
  • Slippery: We have noticed that it is a little more slippery than the Samsung Galaxy S6. With a little care, there is no problem, but it is not bad to notice.
  • Audio: It would not hurt to give a little more prominence to the audio by placing the speaker in a place that helps more to it, as in the front.
