Electric cars were designed to ensure that there was an environmentally friendly way to transport yourself from point A to point B. However, many challenges have faced this new breed of car, and one of these difficulties is the lack of miles that someone can get from a fully charged engine. However, recent progress in the field may have created a way around that problem.
So, what has the new progress achieved?
Scientists have been experimenting with the electric car to find out how to increase the number of miles the vehicle can travel when it has been charged. To do this, the basic idea was to make a minor adjustment to the magnetic field inside the car to create a hybrid design. The invention combines the technology found in the traditional permanent magnet machine, and then blended it with the salient pole machine. The latter of the two devices uses electromagnets as opposed to permanent ones, and by combining the best features of the two, the electric motor in the car itself has been significantly upgraded and made more efficient.
The two motors had previously been used to create the hybrid reach peak efficiency at completely different times, which means that any overall benefits aren’t accessible by just combining the two machines. Instead of this, the new motor has been designed to allow the parts to reach peak efficiency at precisely the same time. However, this motor is still in the prototype stage, as reconfiguring the technology is not as straightforward as you would think.
The new challenges we face
The problem is that there is a reduced torque output when the motor is working as a generator, and thus it cannot recycle energy as efficiently as existing models. Therefore, the new challenge to face scientists is making the torque output at the same level as current models before the new engine can be put into use. The new engine utilises wires and magnets to generate the required magnetic field, but the design will need a type of rotor that that can create the necessary shapes for the engine to work.
Overall, while the new technology does sound appealing and is a definite step in the right direction, the technology is still in an experimental phase, and thus it is difficult to predict exactly when the engine will become ready for public usage. The need to find a rotor that can shape the magnetic fields correctly is one of the major issues. There is also the problem of actually configuring the technology of the two engines to create a compatible hybrid that can reach efficiency at the right time as and when needed.
However, the news is promising and does suggest that advancements are being made with regards to electric cars, which may be an indicator that the technology will become more and more efficient as time goes by.
