The AC decelerating motor with superior quality has a service life of several decades or even more without accident. With the progress of production technology of Foshan Yongkun motor and the continuous introduction of new materials and processes, Yongkun launched Y Series and Y2 series later in 2008, and then YX and ye series high-efficiency AC deceleration motors, and ye3 series ultra-high efficiency motors and more energy-saving three-phase AC deceleration motors in 2012. The performance index of these motors is higher and higher, especially the energy saving effect is obvious. Maybe some people will struggle, "the motor that has been used for decades has already crossed several series. Do you want to change it?"?
As the power unit of the driving equipment, the traditional low efficiency AC decelerating motor does not have high requirements for its operation parameters and is not a vulnerable equipment in most operating environments. Many J series traditional low efficiency AC decelerating motors produced in the 1960s are still in normal operation in many enterprises. In the market economy, some enterprises are short-sighted and reduce costs to purchase, which is a contradiction with the high price of efficient motor. As long as the normal operation of the reducer motor production, most enterprises generally do not put forward additional investment to replace the more efficient reducer motor, which is the main factor of the difficulty in promoting the efficient motor. In addition, the information asymmetry, the idea dislocation, the market non-standard, the energy-saving consciousness is not strong and so on also becomes the high-efficiency motor promotion barrier in our country.
In order to accurately test the energy-saving effect of high-efficiency motor and traditional reduction motor, some mechanisms have done experiments. The efficiency of y160m1-2 motor is 82.24%, while ye3-160m1-2 motor is 86.42% and the efficiency is increased by 4.18% when the traditional low efficiency AC reduction motor is operating at 50% load rate; when the low efficiency AC reduction motor is operating at 75% load rate, the efficiency of y160m1-2 motor is 85.59%, ye3-160m1-2 motor is 89.16% and the efficiency is increased by 3.57%. From the field test results, the energy-saving effect is obvious. Therefore, it is necessary to replace the low efficiency AC motor with the high efficiency motor.
Foshan Yongkun precision mechanical and Electrical Co., Ltd. believes that efforts should be made to implement the process of replacing inefficient AC reducer motor with efficient motor from these aspects:
1、 Compulsory laws and regulations, clear rewards and punishments, and in place responsibilities;
Second, put forward higher requirements and implementation goals for the economically (industrial) developed areas;
Third, increase financial subsidies, key subsidies for key enterprises and extra subsidies for excess enterprises;
Fourth, the classified and batch transformation or construction of fully efficient and energy-saving motor application (pilot) enterprises and the transformation of pilot enterprises into benchmark enterprises;
Fifthly, fifthly, research and reduce the production cost of high-efficiency motor; sixthly, try to require high standards or even exceed standards, such as selecting rare-earth permanent magnet NdFeB motor.
In order to save energy, Foshan Yongkun precision mechanical and Electrical Co., Ltd. suggests that the enterprises that still use the traditional low-efficiency AC decelerating motor should be replaced with the high-efficiency and energy-saving decelerating motor, so as to set an example for the task of energy conservation and emission reduction and the special action of industrial green development in the 13th five year plan.
