Electric motor efficiency

Because roughly 60 percent of the world's electricity is used to power motors, motor control is a high-growth market. TI chips decrease motor energy consumption as much as 60 percent by enabling, for example, variable speed drives and properly sized motors for a variety of applications, including heat and air-conditioning systems, appliances, fans, blowers, e-bikes, pumps and compressors. Aside from the tremendous energy savings, these motor drives extend product life spans, reduce noise, and improve reliability.

To improve our understanding of motor control and design new technology to improve efficiencies, we operate a Motor Lab within Kilby Labs. We have several product lines for advanced motor-control and motor-drive solutions, as about 10 billion motors are shipped globally each year and developing countries are beginning to use more.

For example, our electronics are bolstering the efficiency of motors used in building ventilation systems in many ways, bringing them up to speed gradually. This produces much greater efficiency than a simple on/off approach. We are also developing advanced algorithms to replace a number of mechanical parts in these motors, reducing both manufacturing costs and mechanical repairs.

When applying our technology to motors in home-ventilation systems as well – to a typical home's refrigerator, washer, dryer, dishwasher, power tools and even children's electronic toys – the benefits of efficiency spread rapidly.

Battery management

TI has pushed advancements in low power for more than 20 years, starting with the company's early focus on battery-life requirements for calculators. This work continues today based on demand for low-power, energy-efficient solutions. Our dedicated Energy Lab is the focal point for developing intelligent energy-conversion and management systems for accessible and cost-effective power delivery.

Our battery-management solutions can be found in hybrid and electric vehicles, e-readers, digital cameras, tablets and smartphones, power tools, smart grids, smart vehicles, cloud computing, and even medical devices.

At data centers, our energy controllers and sensors protect and prolong battery life, maintain their charge, and balance battery cells to ensure uninterrupted power for the Internet and the transmission of significant digital data.

Electric and hybrid vehicles use lithium-ion battery cells that depend on sophisticated TI semiconductor technologies to deliver top performance. Our solutions allow these batteries to:
  • Perform in extreme environmental conditions.
  • Operate predictably so that consumers can rely on the stored electrical energy.
  • Extend the usable battery life for a decade or more, or 150,000 miles.
  • Be compact and lightweight.
Our battery-management devices are installed in vehicles produced by a variety of American, European, Japanese and Chinese manufacturers.

Lighting/LED

With 20 percent of the world's energy used for lighting – and more than 10 billion lights purchased each year – energy-efficient light-emitting diodes (LEDs) are critical to reducing energy use.

Made with semiconductors, LEDs are twice as efficient as fluorescent lighting, durable, controllable and generate very little heat. Depending on usage, LED light bulbs can last as long as 20 or 30 years. Because LEDs will be widely adopted in the coming years as they become more cost-effective, our LED Lighting division is poised to unveil new technologies that will enable and accelerate mass-market acceptance.

Long-lasting, energy-efficient lighting yields environmental benefits by lowering energy requirements, while reducing the amount of mercury-containing light bulbs disposed in landfills.
