Motors and engines are more effective than internal combustion engines, but that does not mean that motors are "future". Not so fast.
The motor operates on the basis of the electromagnetic principle, which is driven by a three-phase AC current (in the case of an AC motor) or a battery (in the case of a DC motor), and the only source of low efficiency is friction and transmission loss, which may be secondary although the internal combustion engine itself has a theoretical efficiency limit of 100% (Kano efficiency). Rate).
As a result, the efficiency of the motor is as high as 85% to 90%. If the thermal efficiency exceeds 40%, the internal combustion engine is very lucky.
