At present, my country’s industrial energy consumption accounts for about 70% of the total energy consumption, of which the motor energy consumption accounts for about 60% to 70% of the industrial energy consumption. In addition to the non-industrial motor energy consumption, the actual energy consumption of the motor accounts for about 50% of the total energy consumption. Above, the current application of high-efficiency energy-saving motors is low. According to a sample survey of 198 motors from key domestic enterprises conducted by the National Center for Quality Supervision and Inspection of Small and Medium-sized Motors, only 8% of them have high-efficiency and energy-saving motors that reach level 2 or above, which is a huge waste of social resources.
Features of high-efficiency motors
1. It saves energy and reduces long-term operating costs. It is very suitable for textiles, fans, water 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;
6. Power saving budget: Taking 55 kilowatt motors as an example, high-efficiency motors save 15% of electricity compared to ordinary motors. The electricity bill is calculated at 0.5 yuan per kilowatt-hour. The cost of replacing the motor can be recovered by saving electricity within one year of using energy-saving motors.
Future development of high-efficiency motors
Favorable policies drive the industry to advance to the high-end. The prospects for my country’s motor market are expected. For a long time, due to technical limitations, my country’s motor manufacturers have focused on the low-end market, which has led to more and more crowded domestic markets, but there will be progress if there is competition. , Accompanied by domestic manufacturers "fighting together", my country’s motor market has gradually moved towards the high-end field. In the context of global reduction of energy consumption, high-efficiency and energy-saving motors have become the consensus of the development of the global motor industry.
In the future, my country will gradually increase its efforts to promote high-efficiency motors, eliminate low-efficiency motors in use, develop high-efficiency motor remanufacturing, and comprehensively promote the development of motor products in the direction of high efficiency, high reliability, light weight, and miniaturization, and further promote energy conservation. The length of the motor’s life has a very large relationship with the temperature rise, improving the efficiency of the motor and reducing the temperature rise can effectively extend the service life of the motor. The lightweight and miniaturization of the motor will help save materials and space. Therefore, the development of high-efficiency and ultra-efficient small and medium-sized motors, special motors for speed regulation, energy-saving control products for motor systems, and research on green energy-saving technologies for motors and systems have become a new development trend in the motor industry.
