Energy Saving Technologies for Railway Traction Motors

Energy-saving Technology for Railway Traction Systems Using Onboard Storage Batteries

Motomi Shimada Yoshihiro Miyaji Takashi Kaneko Keita Suzuki OVERVIEW: The first application for onboard storage batteries came with the commercialization of series hybrid drive systems that reduced the fuel consumption of diesel trains. Storage battery control has also been used for the absorption of regenerative electric power and to implement the regenerative brake with extended effective spe...

Energy Saving in Evaporative Coolers using Permanent Magnet Brushless Motors

Due to low cost, evaporative coolers are used in most of the central regions and in the warm and dry climate of Iran and are considered as one of the major consumers of electrical power. Most evaporative coolers use single-phase induction motors by connecting directly to the power grid. But their eefficiency is very low, and their replacement with high efficiency electric motors is considered b...

1 Railway Traction

The railway as a means of transport is a very old idea. At its beginnings, it was mainly utilised in the central European mines with different means of traction being applied. But it did not come into general use until the invention of the steam engine. Since the 18th century it has developed faster and faster until in the 21st century it has become the most efficient means of transport for med...
