A motor is a machine that converts electric energy into kinetic energy, and works behind the scenes to support our pleasant and convenient lifestyles.
In 1910, the history of the Hitachi Group began with the completion of a "5-horsepower motor" as the first all-Japanese motor. Over more than 100 years since then, motor performance has steadily evolved. And now, motors must be highly efficient while saving energy.
Motors serve active roles in various fields, even though we may not often notice them in our daily lives.
In our immediate surroundings, motors are used in home appliances (such as washing machines and air conditioners), vehicles, production facilities (in all fields of industry), building equipment (such as elevators and escalators), and railway cars.
In January 2011, the Ministry of Economy, Trade and Industry in Japan (METI) decided to apply "Top Runner Energy Efficiency Standards" to industrial motors.
The standards mainly apply to "three-phase induction motors" that are used for such equipment as pumps, blowers, and compressors in many industrial sectors.
According to survey results obtained in 2009 by the Agency for Natural Resources and Energy, about 100 million three-phase induction motors are now being used in Japan, and their power consumption accounts for about 55% of the nation’s total power consumption.
According to a certain provisional estimate, replacing all industrial motors with motors that meet Top Runner Energy Efficiency Standards could reduce power consumption by about 15.5 billion kWh per year, thus achieving an extremely high energy saving effect.*1
The Top Runner Energy Efficiency Standards will apply to all three-phase induction motors starting in 2015.
The "Top Runner Energy Efficiency Standards" are regulations aimed at conserving energy as applied to manufacturers. For each commercialized target product item, a product having the highest energy efficiency is deemed a top runner, and the regulations require manufacturers to produce products targeting the top runner as the standard. The target values are very high out of necessity, as these regulations are intended to prompt manufacturers to develop products of higher efficiency. Consumers can contribute to energy conservation by simply replacing their old products with such new ones, thereby promoting global energy conservation.
In response to the determination of the outline of Top Runner Energy Efficiency Standards concerning three-phase induction motors, Hitachi Industrial Equipment Systems Co., Ltd. has released "The Motor Neo100 Premium" series of highly efficient motors.
Based on the results of long years of developing highly efficient motors, "The Motor Neo100 Premium" series introduced by Hitachi Industrial Equipment Systems achieves higher energy efficiency and thus meets Top Runner Energy Efficiency Standards. In particular, great energy saving effects can be expected from equipment (such as pumps and blowers) being used continuously for a long time.
Motor technology continues evolving in pursuit of higher efficiency. The industrial Amorphous PM Motor, which is not using rare earth metals that may soon be depleted, is scheduled to be available in 2015.

Hitachi also succeeded in developing another industrial motor which achieved the world's highest energy efficinecy level(IE5).
In order to assume a long, pleasant, and convenient life, we must continue to reduce environmental burden such as saving energy.
Hitachi will continue to help save energy with our highly efficient motors, and promote the development of environmentally conscious products.
