Japanese seiko corporation in view of the current motor energy requirements rise ceaselessly, the latest developed "energy saving motor with low loss bearing".DU bushing This product can make bearing the internal friction losses to the original half, so as to achieve the purpose of saving energy. NSK forecast that by 2016 the product sales reached 7 billion yen.
Mould guide plate Development background
In recent years, to stop global warming, countries are committed to realize the energy saving and emission reduction. Especially motor, accounting for production in the areas of power consumption by 75%, therefore, countries are actively promote their motor in energy efficiency standards, in order to reduce energy consumption. plasic bushing The international electrotechnical commission (hereinafter referred to as the IEC) in 2008 in a unified release the international motor energy efficiency standards.plain bearing The motor of the factors to energy efficiency, iron loss, copper loss, the line loss, such as wind damage loss of motor itself accounted for 90%, from bearing accounted for only 10% of the loss. brass bushing the future to a higher level with the motor of the ﹡ IE3 IE4, such as the energy efficiency standards, on the low loss of bearing requirement also will be further improved.
IE3, IE4 level: IEC make energy efficiency of the level, IE1 (standard) ? IE2 (a highly energy-efficient) ? IE3 (highly energy-efficient) ? IE4 (high efficiency)
Product features
This product by the following special skill, and realize the high-speed operation but also improves the durability.
Compared with the original products should, loss reduced by half.
Through the bearing optimization design, realization loss in half.
Product performance
1. Improve the motor of high efficiency energy saving effect
Can supply must be in accordance with the IE3 IE4, JIS or energy efficiency standard the energy conservation product, reduce the power consumption of the motor.
2. To improve reliability
Through the low bearing loss, inhibit the rise of temperature of the bearing, so as to improve the reliability of the motor and equipment.
