Energy storage motors utilize various energy storage technologies, such as batteries, supercapacitors, or flywheels, to enable high-frequency energy delivery. These storage mediums ensure rapid
Motor-driven systems in the industrial sector consume approxi-mately 632 billion kWh/year, or 44% of all motor-driven system energy use. This industrial sector motor use equates to about 17% of the total U.S. electrical energy use. Within the industrial sector, about 62.5% of the total electrical energy use is for motor-driven equipment.
Full-load motor eficiency values are available from the motor nameplate or manufacturer’s catalog, while part-load eficiency values can be obtained from the manufacturer or DOE’s MotorMaster+software tool.
The energy savings summary above shows that a 3% gain in motor eficiency saves far more (over 455% more) than the annual dollar savings due to a 5 mpg increase in vehicle fuel economy. Over a 20-year operating period, the standard eficiency motor would consume over 330,000 kWh more than a premium eficiency motor put into the same service.
In the scenario of a new motor purchase, Table 4-1 shows the annual energy and dollar savings from the selection and use of a premium efi-ciency, rather than an energy eficient motor model. Dollar savings are based on an average energy rate of $0.08/kWh.
The minimum eficiency level for energy eficient and premium eficiency four-pole (1,800 RPM) motors is given as a function of motor horsepower rating in Figure 2-1. The performance of typical standard eficiency motors is also shown. Figure 2-1 indicates that motor eficiency increases with motor size.
Energy and power savings can be obtained directly by shutting off idling motors to eliminate no-load losses.5-16 This action also greatly improves the overall system power factor, which in turn, improves in-plant electrical distribution system eficiency. Typical no-load or idling motor power factors are in the 10% to 20% range.
