Summary: Nippon 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, countries are committed to achieving energy conservation and emission reductions. In particular, motors, which account for 75% of the electricity consumed in various fields such as production, are actively promoting their respective motor energy efficiency standards in order to reduce energy consumption. In 2008, the International Electrotechnical Commission (hereinafter referred to as IEC) 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.
IE3, IE4 rating: Energy efficiency rating set by IEC, IE1 (standard) ⇒ IE2 (higher energy efficiency) ⇒ IE3 (high energy efficiency) ⇒ IE4 (ultra high energy efficiency)
Product Features This product achieves ultra-high speed operation and durability by the following features.
â—† Compared with the original product, the loss is reduced by half.
Through the optimal design of the bearing, the loss is reduced by half.
Product Performance 1: Improve the motor's energy-saving effect Energy-saving products that meet JIS or IE3, IE4 high energy efficiency standards can be supplied to reduce the power consumption of the motor.
2: Improve reliability By Reducing the bearing loss and suppressing the temperature rise of the bearing, the reliability of the motor and equipment is improved.
