Enzymes differ from most other catalysts by being much more specific. Enzyme activity can be affected by other molecules: inhibitors are molecules that decrease enzyme activity, and activators are molecules that increase activity.
This fact sheet briefly discusses several load estimation tech-. niques. Reasons to Determine Motor Loading. Most electric motors are designed to run at 50% to 100% of rated load. Maximum efficiency is. usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of. 5 to 10 hp; peak efficiency is at 7.5 hp. A motor âs efficiency tends to decrease dramatically below. about 50% load. However, the range of good efficiency varies with individual motors and tends to. extend over a broader range for larger motors, as shown in Figure 1.
Which means electric motors are about 4x more efficient than combustion engines. You can find additional details and sources in my other answer to What percentage of battery power is lost due to heat generated by the electric motors in a Tesla Model S?
