Scope

1.1 This Rules is formulated in accordance with the "Measures for the Administration
of Energy Labels" (hereinafter referred to as the "Measures").
1.2 This Rules is applicable to the use, filing and announcement of energy labels
(hereinafter referred to as labels) for general purpose three-phase asynchronous motor
or general-purpose explosion-proof three-phase asynchronous motor. The rated voltage
of the motor is 1000 V and below. It uses 50 Hz three-phase AC power supply. The
rated power is in the range of 0.75 kW ~ 375 kW. The number of poles is 2 poles, 4
poles, 6 poles and 8 poles. It has single-speed closed self-fan cooling, N design and
continuous work system.
Inapplicable motors mainly include.
(1) Motors that are fully integrated with other equipment such as pumps, fans,
compressors and reduction gearboxes and cannot be tested separately;
(2) Motors specially designed for driving special machinery (e.g., with large starting
torque, special requirements for torque stiffness and/or ultimate torque
characteristics, large number of drive/stop cycles);
(3) Specially designed motors that are used in harsh power supply environments (for
example, the starting current of the motor cannot be too large, and the grid voltage
and/or frequency fluctuates greatly);
(4) Motors used under special environmental conditions, such as motors installed at
high altitudes ( >1000 m), smoke exhaust motors (temperature levels exceeding
250°C and above), textile motors, special motors for ships, etc.;
(5) Explosion-proof motors manufactured for safety needs and specific design
restrictions (such as increased air gap, reduced starting current, enhanced sealing);
(6) Motors specially designed for changing working conditions;
(7) Conical rotor motors for electric lifting hoists and construction machinery;
(8) Motors that the electromagnetic brake is inside the motor casing (the fan cover
is inside the casing and outside the casing);
3.2 The format of the "Energy test report for small and medium-sized three-phase
asynchronous motors" (hereinafter referred to as the test report) is shown in Appendix
2.It can be downloaded from the "China Energy Label Network"
3.3 Producers or importers can use their own testing laboratories or entrust third-party
inspection and testing institutions that have obtained qualifications in accordance with
the law to test products. Determine product energy levels based on mandatory national
standards for energy.
Producers or importers who use their own testing laboratories to determine energy
levels shall ensure that their testing laboratories have the ability to conduct testing in
accordance with mandatory national standards for energy, and are encouraged to obtain
accreditation from national accreditation agencies.
3.4 If a self-owned testing laboratory is used for testing, materials proving the
laboratory's testing capabilities (including laboratory personnel capabilities, equipment
capabilities, and testing management specifications) must be provided. If it has been
accredited by a national accreditation agency, a copy of the corresponding accreditation
certificate shall also be provided. If a third-party inspection and testing agency is used
for testing, a copy of the inspection and testing agency’s qualification certificate shall
be provided.
Authorized agencies shall verify the energy labels and product energy test reports used
by manufacturers and importers.
