there are still some enterprises that are reluctant to replace high-efficiency motors, because the price of high-efficiency motors is higher than that of ordinary motors, which will lead to rising costs.

But in reality, this masks the cost of procurement and the cost of energy consumption

The purchase cost of electric motors accounts for only 2% of the total cost

Maintenance costs account for 0.7% of the total cost,

The cost of energy consumption accounted for 97.3%.

This account, boss, you still can’t figure it out?

To explain it in detail with real events on the Internet:

Air China Co., Ltd. (hereinafter referred to as International Airline) was punished by the Beijing Municipal Development and Reform Commission for energy conservation and confiscated energy-using equipment that the state had eliminated. The details are as follows:

It is reported that the Beijing Municipal Development and Reform Commission (NDRC) monitored whether international airlines used energy-using equipment and production processes that had been eliminated by the state from August 2020, 8 to November 31, 2020, according to the daily supervision work arrangement. After verification, 11 motors, including the Y series three-phase asynchronous motor Y12M-225 type used by international airlines, belong to the energy-using equipment eliminated by the state in the “Catalogue of Elimination of Backward Mechanical and Electrical Equipment (Products) with High Energy Consumption (Second Batch)” (Announcement of the Ministry of Industry and Information Technology of the People’s Republic of China No. 4 of 11). The penalty decision to confiscate 2012 motors including Y14M-225 type three-phase asynchronous motor of the Y series was imposed.

In addition to this, there are:

✔ Beijing Beiheavy Truck Turbine Motor confiscated 15 units

✔ Communication University of China confiscated 14 units

✔ Sany Heavy Industry confiscated 15 units

✔ CRRC Beijing Erqi Locomotive Company confiscated 9 units

✔ Beijing Hualian Supermarket confiscated 17 units

In addition to the above-mentioned “negative cases of the use of energy-intensive motors”,

And these market data:

In 2011, China’s motor ownership was about 17.3 billion kilowatts, and the total power consumption was about 64 trillion kilowatt-hours, accounting for <>% of the total electricity consumption of the whole society;

Electric motors in the industrial field consume about 2.6 trillion kilowatt hours, accounting for about 75% of industrial electricity;

The United States and Europe have mandated high-efficiency motors since 1997 and 2011, respectively;

The average efficiency of electric motors in China is 3-5 percentage points lower than that of foreign countries, and the operating efficiency of motor systems is 10-20 percentage points lower than that of foreign countries;

In order to change the status quo of high-energy-consuming motors, China’s electric motor-related mandatory policies and new standards have been issued and implemented.

The Ministry of Industry and Information Technology and the State Administration for Market Regulation issued the “Motor Energy Efficiency Improvement Plan (2021-2023)”, which proposes to guide enterprises to implement the update and upgrading of key energy-using equipment such as electric motors, give priority to high-efficiency and energy-saving motors, and accelerate the elimination of backward and inefficient motors that do not meet the requirements of the current national energy efficiency standards.

Increase the application of high-efficiency and energy-saving motors. Subdivide the load characteristics and different working conditions, and encourage the use of motors with level 2 energy efficiency and above for general equipment such as fans, pumps, compressors, and machine tools. For variable load operation conditions, promote level 2 energy efficiency and above variable frequency speed regulation permanent magnet motor.

And in the recently implemented “Industrial Energy Conservation Supervision Measures” has clear requirements for backward energy-consuming energy-using products, equipment, production process elimination systems, etc

The benefits of energy-saving motor equipment replacement for businesses

The necessity of energy-efficient electric power engines in the fan pump industry

According to statistics, the annual power consumption of fans and pumps in China accounts for 31% of the country’s power generation and about 50% of industrial electricity, of which 70% are in line with operation. It can be seen that the speed regulation and energy saving potential of fans and pump motors is very large.

From the perspective of best economic benefits and energy saving, reducing the power loss in the operation of motors with fans and pumps is an effective measure and the best choice to improve the efficiency of the entire system and achieve high efficiency and energy saving.

The necessity of energy-efficient electric actuators in the textile industry

According to statistics, the annual working time of textile motors is more than 7000h, if the energy-saving program is implemented, its high-efficiency and energy-saving effect will be very prominent.

For example: change the general efficiency motor 91.2% to the national standard 2 level energy efficiency 93.9%, power 37KW, annual operating hours 7000h, annual power saving = power 37X (100/91.2-100/93.9) X 7000=9165.5.

And at present, the textile industry has begun to enter a period of slow development, it is the moment when changes need to be made, the choice of high-efficiency motors is once and for all, but also an effective measure to improve the competitiveness of enterprises.

The necessity of energy-efficient electric motors in the compressor industry

Friends in the compressor industry should know that the motor on the air compressor is a direct converter of energy, and its energy-saving benefits are crucial.

However, many compressor manufacturers are reluctant to use high-efficiency motors because the price of high-efficiency motors is higher than that of ordinary motors, which will cause the cost of rising costs, but this is to cover up the cost of energy consumption.

In the life cycle of the motor, the purchase cost of the motor only accounts for 2% of the total cost, the maintenance cost accounts for 0.7% of the total cost, and the energy consumption cost accounts for 97.3%, in order to improve the efficiency of compressor operation and reduce energy consumption, it is necessary to use energy-efficient motors.
