The energy consumption level of the motor is divided into several levels, and the energy efficiency division standard

The energy consumption level of the motor is divided into several levels, and the energy efficiency division standard   

Electric motors are power-driven equipment for various equipment. They are often used in many industries and fields such as chemical plants, coal mines, metallurgy, and public facilities. In order to respond to the national twelfth five-year plan and consider the economic benefits of the enterprise itself, to save electricity and reduce costs, it is very important to choose an efficient and energy-saving motor.   

But when we buy motors, we don't know how their energy efficiency is divided. How to judge the energy efficiency level of the motor is difficult for us, but after our explanation below, we will understand how the energy efficiency of explosion-proof motors is divided.   

The classification standards of motor energy efficiency standards are not the same according to national standards in different periods, and the standards are also different according to different countries. For our country alone, the division of motor energy efficiency levels also changes over time. In 2006, China issued GB_18613-2006_ motor energy efficiency limit values and standards for energy efficiency rating.

 

GB_18613-2006_Electric motor energy efficiency limit and energy efficiency level   

But in 2012, with the development of China and the internationalization, our country could not issue the GB_18613-2012_ motor energy efficiency limit value and energy efficiency level judgment standards, as shown in the table below.

It is not difficult to see the following table on some models

Take the current energy-saving and explosion-proof motor YBX3, in GB_18613-2006_ motor energy efficiency limit value and energy efficiency standard is first-level energy efficiency, but to GB_18613-2012_ motor energy efficiency limit value and energy efficiency level standard is second-level energy efficiency. The YB2 series belt motor is a second-level energy efficiency motor in the GB_18613-2006_ motor energy efficiency limit value and energy efficiency rating standard, but according to the 2012 motor energy classification standard, it belongs to a third-level energy-consumption explosion-proof motor. Energy consuming motor. Of course, with the development of science and technology and the increase in the requirements for energy saving of explosion-proof motors, the energy efficiency standards may change. Therefore, the energy efficiency levels of different methods of judgment will be different.   

Now we take the latest energy efficiency standards of our country, currently according to GB_18613-2012_ motor energy efficiency limit value and energy efficiency level classification standard requirements, explosion-proof motor energy efficiency level is divided into three levels. One level of energy efficiency is the most energy-efficient, and the two-stage energy efficiency explosion-proof motor is also an energy-saving and explosion-proof motor. Of course, the third-stage energy efficiency is not an energy-saving explosion-proof motor. Of course, the explosion-proof motors at the second level and above (for the time being, the first-level energy-efficient three-phase asynchronous explosion-proof motors have no products in China, and the YBX3 is the best choice) are all promoted by the country now, and some local countries will give certain policy subsidies. . For enterprises, energy saving will also save a lot of money every year.
