Japan Seiko successfully develops low-loss bearings for energy-saving motors

Japan Seiko Co., Ltd. has recently developed a "low-loss bearing for energy-saving motors" in response to the continuous improvement of current motor energy-saving requirements. This product can reduce the friction loss inside the bearing to half of the original, so as to achieve the purpose of energy saving. NSK predicts that sales of this product will reach 7 billion yen by 2016.

Development Background In recent years, in order to prevent global warming, all countries are committed to achieving energy conservation and emission reductions, especially for motors, which account for 75% of power consumption in various fields such as production. For this reason, countries are actively implementing their respective motor energy efficiency standards. Reduce energy consumption. In 2008, the International Electrotechnical Commission uniformly formulated and issued international standards for motor energy efficiency. Of the factors that determine the energy efficiency of a motor, the loss of the motor itself, such as iron loss, copper loss, line loss, and wind loss, accounts for 90%, and the loss from the bearing only accounts for 10%. With the advancement of the motor to higher-level energy efficiency standards such as *IE3 and IE4, the low-loss requirements for bearings will be further increased.
