There is an additional caveat: if you search for "electric motor efficiency map" you will find graphs that show that at low power (rpm x torque) electric motors have low(-ish) efficiency.
If I get this right it means you still have an area of rpm x torque where you want your electric motor to be for peak efficiency.
