How Proper Applications of Thermally Conductive Materials will Improve Motor Power Density

Posted on 30 July 2015

      Motor designers have battled heat in motor designs for years. Thermal losses in electric machines rob motion systems of power and degrade efficiency. Excess heat can reduce reliability of motors and shorten their lifetimes. Meanwhile, electrification in all transportation sectors is driving requirements for motors with ever-higher power densities. By Anita LaFond, [...]

Unique PFC Controller for Design Challenges of Packaged Air Conditioner

Posted on 06 August 2014

      Air conditioners are an important appliance in almost every residential and commercial building. While both window-type and duct-type air conditioners are common in the market today, duct-type air conditioners are becoming more main stream today due to their ease of installation. By Wen Chien, BLDC Product Line Marketing Manager, Fairchild Semiconductor However, [...]

Decentralized Drive Technology Solution with MPU

Posted on 05 August 2014

      In factory automation, decentralized drive solutions have many benefits over centralized drive solutions. For the latter, the frequency inverter and control unit is mounted inside a control cabinet and it requires multiple cabinets as well as star cabling topology for each drive. By Thomas Mauer, Texas Instruments Decentralized drives have the frequency [...]
