Electric Motors - Better Than the Combustion Engines
Electric motors are known as a viable alternative to the combustion engines because of their multiple advantages. The majority of brands have made the impossible to work with electric motors and improve them according to the contemporary requirements.
Many people don't believe in the compatibility between an electric motor and a combustion engine. Especially if this is related to the rapid increase in terms of oil pricing. Thus it is always a good idea to know the benefits of running an electric motor as opposed to the combustion engines available nowadays.
Design and performance | E Cars
The electric motors have a more interesting design, being compact and fitting everywhere in the car. When it comes to performance, they are better than the gasoline or diesel models. Why? Because they have a power source (usually batteries) that is connected to the electric motor with the help of a convertor and a controller. This is utilized in order to enable the use of AC to the motor. This means that an electric motor requires a smaller number of mechanical items and causes less tear to the components that are already doing their job.
Friction and maintenance
Another great advantage of the electric motor is the fact that it doesn't have a great friction loss as opposed to the combustion engines. In this case, the energy is transformed into motion while running, making the acceleration constant and immediate.
Moreover, these motors don't need to be maintained that often and don't require engine oil or coolants. They are very silent and the heat liberated is not as intense as in other cases. The vibrations can hardly be perceived, if the engine is not modified in any way.
No gears or tank
Electric motors do not have gear but a mechanism to differentiate the back and forth movement. For some, this represents an opposite of the motor itself. Furthermore, by not having a tank with oil like in any other situation, this motor has the possibility to decentralize the movement generation. This means that more motors are used as opposed to one single motor that is hooked to a transmission. All you need is software to help the motors work together.
An electric motor does not need a clutch to exert torque and it can economize braking energy in order to recharge the batteries. In terms of fuel consumption, it has an efficiency of almost 90 percent. This means that this energy is consumed while driving using the battery to its full potential. On the other hand, the diesel engine has an efficiency of only 40 percent. Not to mention that this technology is eco-friendly and costs less than the existing alternatives.
This is the main weak point of the entire system. But this is not a terrible thing, since batteries are constantly being improved and made easier to charge. Taking into account that more people realize that the Earth should be preserved properly, the ecological responsibility grows too. Giving up on a few commodities is not a big price to pay for a clean and healthy planet.
Everything You Wanted To Know About Electric Car Engines
EV motors (electric vehicle) are basically DC Motors (Direct Current Motors) in most cases and the volt range vary from 96 to 192 volts. However AC Motors (Alternate Current Motors) are also used and in this case, the volt range can be anywhere between 240 and 300 volts. The most common electric car motors are the direct current motors because these motors are very easy to install and are usually not expensive as the alternate current motors. Apart from the simple setup, there is one more reason to rely on DC motors.
It is none other than the ability of electric motors to boost its wattage for a fraction of seconds, usually 5 times than its original output. Due to this, DC cars can have better acceleration for a very short span of time and this will help the car to perform better. However, this can't be done for so long as the engine will blowout. However, AC motors are installed in some cars because these engines can allow any industry specified motor to be used in the car which is quite advantageous.
The car's working principle is quite simple:
Drivetrain - In battery-powered cars, the working principle is very easy to understand. The car is driven by a motor (electric motor) which directly takes its energy from the cells. In hybrid cars, there are gasoline powered generators. Hybrid cars have a very sophisticated mechanism, which is not in the scope of this article. Coming back to electric cars, the straightforward mechanism avoid many components in between and it makes these cars more reliable.
Gear Box - Compared to gasoline powered vehicles, EV engines can't be pressured to produce more torque by switching to a lower gear. As we have seen earlier, DC motors can boost the power for a couple of seconds but car manufacturers do not use this option as a technique to boost the power. We can conclude that the gear box in an electric car engine is only to control speed. The working principle is also very different. It uses a resistor and the lower speed is achieved by putting higher resistance on engine.
Cells - Earlier, the car battery was the biggest downside of electric cars because on average, these batteries weight around 500 to 1,000 pounds. These days, there is sophisticated technology in branded cars but that technology does not come at a very reasonable price. Even the smallest cars with Li-ion battery setup will cost you a lot as the battery pack is quite expensive.
These are the major features of EV engines. Earlier, electric car batteries were identical to the car batteries (even today, many aftermarket electric car kits use the same) but these batteries will not last longer. The gel electrolyte based cells are expensive but long lasting too. If you want a reliable motor and battery setup for your investment, it is a good idea to stick to the latter.
