” because they make maximum torque at ANY AND ALL RPMs.”
Each type of motor has a characteristic torque curve. None make max torque at all RPMs.
“Each type of motor has a characteristic torque curve. None make max torque at all RPMs.”
WRONG, electric motors have the same torque at all RPM. Engines have a torque curve.
When measuring torque in lb.ft., the torque and horsepower will be the same at 5252 rpm. Torque is higher than HP below 5252 rpm and HP is higher than torque above 5252 rpm. The 5252 is a mathematical constant that converts the formula for linear horse power into a formula for rotational horsepower. The formula is Torque x HP / 5252.
