The gist, the gas engine wasn’t born a small zippy little engine that could do 30 to 40 miles a gallon. The horse power squeezed out of a 2 liter engine now days wasn’t even extracted from a 12 liters 70 years ago. Yet, it matured. The same thing will happen with the electric engine that will power tomorrow’s cars.
In its basic fundamentals, an electric engine are magnets attracting and repulsing copper coils. But the basic designs are maturing and becoming increasingly sophisticated, which means more and more efficient. Articles, as TheGreenCarWebsite‘s on breakthrough on electric motor efficiency prove the technology is evolving, but more importantly is now recognized as the propulsion choice of the future.
Boosting Efficiency. Can an electric engine’s efficiency be boosted by 97%? The UK-based firm Isis Innovation Ltd believes it can. By redesigning it and using a different lay out from traditional electric engines, along with the use of different materials which reduces the weight, engineers believe overall efficiency goes to 97%. A far cry from gasoline engine’s 66% inefficiency. In other words, a lighter engine developing more torque with less power is the way forward for EVs. The engine could be used for wind turbines, but would excel with regenerative braking systems in EVs and hybrid cars, HEV.
Expect this year to unfold with breakthroughs and innovations as the electric engine matures. After all, electric locomotives have been improving these types of engines for decades.
