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.
An electric motor is an electrical machine that converts electrical energy into mechanical energy. The reverse of this is the conversion of mechanical energy into electrical energy and is done by an electric generator. In normal motoring mode, most electric motors operate through the interaction between an electric motor's magnetic field and winding currents to generate force within the motor.
