Electric motor: more efficient than a combustion engine

Due to certain inherent advantages, electric motors are claimed to be viable and ideal alternatives to internal combustion engines. All brands have launched crazy competitions to launch electric motors and are working hard to achieve the most significant technological advances in this area.

The applicability of using an electric motor instead of an internal combustion engine is often questionable. This is a debt issue due to the sharp rise in oil prices. Therefore, it is important to understand the basic advantages of using an electric motor over current internal combustion engines.

1. Electric motors are more interesting in design because they are compact and can be placed almost anywhere in the vehicle.

2. From a mechanical performance point of view, it is more convincing than a diesel or gasoline model. The principle is simple: the power supply [battery] is connected to the motor through a controller and converter that is used to provide AC to the motor, which requires a smaller number of mechanical components and results in less wear. still need.

The electric motor also has the advantage of not having significant friction losses, as is the case with thermal engines. Instead, energy is converted directly into motion in almost its entity, resulting in immediate and constant acceleration.

4. The motor requires less maintenance and does not require coolant or engine oil.

In fact, they don't generate noise during operation, and the heat generated is negligible.

6. Since the engine is not affected during operation, it is not easy to detect vibration.

7. Except for some mechanisms, the motor does not require gears to distinguish between forward and backward motion, which may be the opposite polarity of the motor itself.

8. A fuel tank that is not filled with fuel powers the engine through pipes, gearboxes and cooling devices, which results in the possibility of dispersing the movement to create and place multiple motors rather than a "central motor" connected to the transmission. You only need some software to synchronize different motors.

9. When it stops, it does not require any clutch to apply torque. Since the motor and generator are substantially identical, it is also easy to recover the braking energy [or a portion thereof] to charge the battery.

10. When it comes to fuel efficiency, the efficiency of the motor is about 90%, which is the percentage of the energy consumed when the battery is available, while the diesel engine is less than 40% efficient due to thermodynamic limitations.

In addition, this latest technology is more environmentally friendly and less expensive than existing combustion fuel driven engines.

The main problem with such motors is not their own, but their power supply - current battery technology is a weak link in large systems. Of course, the battery has been constantly improving, and there are charging methods.

Given the growing ecological awareness of modern society, people are now more than happy to sacrifice the advantages of internal combustion engines rather than electric motors. In fact, if we want to have a cleaner, greener planet, it is wise to make these sacrifices.
