At present, the international development of motor efficiency standards in the United States, Canada, Mexico, Brazil, Australia and New Zealand. China was in the beginning of this year issued a motor energy efficiency standards, and will officially take effect on August 1, 2002. Agreement on the EU-wide European motors and power electronics manufacturers Association (CEMEP) indicators, although not as a European directive, but the EU environmental and energy-saving programs have been included in the Agreement indicators are a EU unified standards compliance.

    U.S. motor EPACT efficiency indicators are developed according to the standard of Electrical Manufacturers Association (NEMA) 90 NEMA12-10 (NEMA12-6C). Provisions. Canadian motor standard (CSA-390), the same as with the United States EPACT efficiency indicators, Mexico, Brazil motor standards of efficiency indicators efficient motor standards developed by the United States NEMA 1989 NEMA12-9 (NEMA12-6B), and its efficiency compared to the United States The EPACT indicators 0.6 to 1.5 percentage points lower. The four countries on motor efficiency test method using the test method specified by the United States EPACT of Electrical and Electronics Engineers standard IEEE112-B.

    China, Australia and New Zealand efficiency indicators is basically the same as the EU CEMEP indicators, test methods and the International Electrotechnical Commission standard IEC34-2. Thus, the current international motor energy efficiency standards, the United States and the European Union standards with some representative below for further information on the progress of these two aspects.

    1. American Standard

    American NEMA efficiency criteria NEMA12-10 formulation, taking into account the demand for higher levels of efficiency, but also to formulate a NEMA E design criteria, i.e. NEMA12-11 standard, and its efficiency indicators representing NEMA12-10 increased from 1 to 4 percentage points , but its starting performance is decreased. In recent years, due to the tense of the U.S. electricity supply, by the U.S. State power company mainly composed of the Consortium for Energy Efficiency (CEE) developed jointly with the United States NEMA starting performance and EPACT consistent with the requirements of ultra-high efficiency motor (Premium Efficiency) indicators, efficiency levels close to NEMA E design, compared with the the EPACT index 1 to 3 percentage points, loss decreased by about 20% compared with EPACT.

    2. EU standards

    CEMEP standards of the EU for each specification motor provides the level of the two tranches efficiency indicators, the value of the product efficiency is lower than the low index called eff3 motor, between the low index and high index between the called eff2 motor, higher than the high index of said for eff1 motor.

    Of power frequency, power and size measurement of the standard as well as the motor power grade and installation size of relations with Europe, at the same time of the motor basic technical requirements and test methods such as standard also and Europe in line with IEC standards, taking into account the the volume of exports of China's motor has reached a considerable number of which 3/4 is sold in Europe and the Asia-Pacific region, only 1/4 sold in North America, so our motor energy efficiency standards to the European CEMEP low-grade value as the minimum energy efficiency limit, ie To achieve this target in domestic production and imports of motor CEMEP high-end value as evaluating values of energy, which meet or exceed the motor of this indicator can be referred to as high-efficiency motor or energy-saving motor.

    CEMEP-EU slightly different, our standards appropriate to increase the power range and number of poles, according to the domestic situation and evaluating values of energy assessment of products, an increase of stray load loss assessment requirements.
