Energy saving and emission reduction is an unavoidable topic in today’s world, which affects the development of the world economy. As a key industrial field for energy conservation and emission reduction. Among them, the motor system has huge energy-saving potential, and electricity consumption accounts for about 60% of the country’s electricity consumption, which has attracted the attention of all parties.

On July 1, 2007, the national standard “Energy Efficiency Limits and Energy Efficiency Grades for Small and Medium-sized Three-phase Asynchronous Motors” (GB 18613-2006) was officially implemented. Products that could not achieved the national standard will not be able to continue to be produced and sold.

What is a high efficiency motor

High-efficiency motors appeared in the first energy crisis in the 1970s. Compared with ordinary motors, their losses were reduced by about 20%. Due to the continuous shortage of energy supply, so-called ultra-high-efficiency motors have appeared in recent years, and their losses have been reduced by 15% to 20% compared with high-efficiency motors. The relationship between the power level of these motors and the installation dimensions, and other performance requirements are the same as those of general motors.

Features of high-efficiency and energy-saving motors:

1. It saves energy and reduces long-term operating costs. It is very suitable for textiles, fans, pumps, and compressors. It can recover the purchase cost of the motor by saving electricity in one year;

2. Direct start or use frequency converter to adjust the speed, the asynchronous motor can be fully replaced;

3. The rare earth permanent magnet high-efficiency energy-saving motor itself can save more than 15℅ electric energy compared with ordinary motors;

4. The power factor of the motor is close to 1, which improves the quality factor of the power grid without adding a power factor compensator;

5. The motor current is small, which saves the transmission and distribution capacity and prolongs the overall operating life of the system;

As an industrial power, motor products rely heavily on the country’s development speed and industrial policies. Therefore, how to seize market opportunities, adjust product structure in time, develop marketable products, choose differentiated energy-saving motor products, and keep up with the national industry Policy is the focus.

From a global perspective, the motor industry is developing in the direction of high efficiency and energy saving, with huge development potential. All developed countries have successively formulated energy efficiency standards for motors. Developed countries such as Europe and the United States have continuously improved the energy efficiency access standards of motors, and basically all have used high-efficiency energy-saving motors, and some regions have begun to use ultra-efficient energy-saving motors.
