Question

Are Electric Motors more powerful than engines?

Answer 1

“not really i mean if you made a 8 cylinder motor with 600 horse it would out run the current elctric motors out there plus they are wimpy soundly

like a blender.”

There are electric motors capable of putting out 600 horsepower continuously (in fact much more powerful motors than that already exist) and they weigh considerably less than any 600 hp combustion counterpart. Electric motors also give instant torque meaning all 600 hp will be released instantly when you ask for them meaning even from a stand still. The combustion engine on the other hand will have to rev up to full rpm before giving its 600 hp while from a stand still its power is really tiny.
The electric motor is also capable of short power bursts during high resistance occurrences where the power surge can rise by several hundred percent. So for a short period this 600 hp electric motor would have no problem giving as much as 2000 or more horsepower where as the combustion engine would still be stuck with its 600 hp… which it can only give at its highest rpm.

Batteries are still the bad part of the electric story and they have a lot of room for improvement. But modern electric motors themselves ridicule combustion engines concerning power and torque.

I fly hobby grade rc helicopters and I want as much power as I can get. I don’t touch combustion engines any more. My electric motors weigh less than the most powerful combustion engines I could use. Still these motors produce about four times more power than these combustion engines.
