Which countries have mandatory requirements for energy efficiency of motor products?

In recent years, our country’s energy efficiency requirements for electric motors and other products have gradually increased. A series of limited requirements for electric motor energy efficiency standards represented by GB 18613 are gradually being promoted and implemented, such as GB30253 and GB30254 standards. Especially for general-purpose motors with relatively large consumption, the 2020 version of the GB18613 standard has stipulated the IE3 energy efficiency level as the minimum limit value for this type of motor. International top level.

Motor companies doing export business should understand the requirements in detail, meet the requirements of national standards, and can only circulate in the domestic sales market. To circulate in the international market with energy efficiency requirements or other personalized requirements, they must meet local standards. Require.

1. America

In 1992, the US Congress passed the EPACT Act, which stipulated the minimum efficiency value of the motor and required that from October 24, 1997, all general-purpose motors sold in the United States must meet the latest minimum efficiency index. , the EPACT efficiency index.

The efficiency index specified by EPACT is the average value of the high-efficiency motor efficiency index produced by the major motor manufacturers in the United States at that time. In 2001, the United States Energy Efficiency Coalition (CEE) and the National Electrical Manufacturers Association (NEMA) jointly developed the ultra-high-efficiency motor standard, called the NEMAPemium standard. The starting performance requirements of this standard are consistent with EPACT, and its efficiency index basically reflects the current average level of ultra-high-efficiency motors in the US market, which is 1 to 3 percentage points higher than the EPACT index, and the loss is about 20% lower than the EPACT index.

At present, the NEMAPemium standard is mostly used as a reference standard for subsidies given by power companies to encourage users to purchase ultra-high-efficiency motors. NEMAPmium motors are recommended for use in occasions where the annual operation is > 2000 hours and the load rate is > 75%.

The NEMAPremium program carried out by NEMA is an industry voluntary agreement. NEMA members sign this agreement and can use the NEMAPremium logo after reaching the standard. Non-member units can use this logo after paying a certain fee.

EPACT stipulates that the measurement of motor efficiency adopts the motor efficiency test method standard IEEE112-B of the American Institute of Electrical and Electronic Engineers.

2. The European Union

In the mid-1990s, the European Union began to conduct research and policy formulation on motor energy conservation.

In 1999, the European Commission’s Transport and Energy Agency and the European Motor and Power Electronics Manufacturers Association (CE-MEP) reached a voluntary agreement on the electric motor classification plan (referred to as the EU-CEMEP agreement), which classifies the efficiency level of electric motors, which is:

eff3 – low efficiency (Lowefficiency) motor;

eff2——Improved efficiency motor;

eff1 – high efficiency (Highefficiency) motor.

(Our country’s classification of motor energy efficiency is similar to that of the European Union.)

After 2006, the production and circulation of eff3-class electric motors is prohibited. The agreement also stipulates that manufacturers should list the identification of the efficiency grade and the efficiency value on the product nameplate and sample data sheet, so as to facilitate the selection and identification of users, which also constitutes the earliest energy efficiency parameters of the EU Electric Motor EuPs Directive.

The EU-CEMEP agreement is implemented after voluntary signing by CEMEP member units, and non-member manufacturers, importers and retailers are welcome to participate. At present, there are 36 manufacturing companies including Siemens in Germany, ABB in Switzerland, BrookCromton in the United Kingdom, and Leroy-Somer in France , covering 80% of the production in Europe. In Denmark, users whose motor efficiency is higher than the minimum standard are subsidized by the Energy Agency of DKK 100 or 250 per kW. The former is used to purchase motors in new plants, and the latter is used to replace old motors. In the Netherlands, in addition to the purchase subsidies, they also give Tax incentives; the UK promotes the market transformation of energy-saving products such as high-efficiency motors by reducing and exempting climate change taxes and implementing the “improving investment subsidy scheme”. Actively introduce energy-saving products including high-efficiency motors on the Internet, and provide information on these products, energy-saving solutions and design methods.

3. Canada

The Canadian Standards Association and the Canadian Motor Industry Association formulated a recommended minimum energy efficiency standard for motors in 1991. The efficiency index of this standard is slightly lower than the later American EPACT index. Due to the importance of energy issues, the Canadian Parliament also passed the Energy Efficiency Act (EEACT) in 1992, which includes the minimum energy efficiency standards for electric motors. effective. This standard is enforced by law, so high-efficiency motors have been rapidly promoted.

4. Australia

In order to save energy and protect the environment, the Australian government has implemented a mandatory energy efficiency standard plan or MEPS plan for household appliances and industrial equipment since 1999, which is managed by the Australian government’s Greenhouse Gas Office in conjunction with the Australian Standards Council.

Australia has included motors into the scope of MEPS, and its mandatory motor standards were approved and entered into force in October 2001. The standard number is AS/NZS1359.5. Motors that need to be produced and imported in Australia and New Zealand must meet or exceed the standards stipulated in this standard. Minimum efficiency indicator.

The standard can be tested with two test methods, so two sets of indicators are specified: one set is the index of method A, corresponding to the American IEEE112-B method; the other set is the index of B method, corresponding to IEC34-2, its index The value is basically the same as Eff2 of EU-CEMEP.

In addition to the mandatory minimum standards, the standard also stipulates high-efficiency motor indicators, which are recommended standards and encourage users to adopt them. Its value is similar to Effl of EU-CEMEP and EPACT of the United States.
