GB18613-2020
Minimum allowable values of energy efficiency and values of efficiency grades for motors
电动机能效限定值及能效等级
GB 18613-2020 is a current mandatory Chinese national standard for Minimum allowable values of energy efficiency and values of efficiency grades for motors. It appears in the Electronics compliance cluster with a energy efficiency focus and has an implementation date of Jun 1, 2021.
Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.
Compliance overview
Scope and applicability
This standard applies to three-phase asynchronous motors, single-phase asynchronous motors, and air conditioner fan motors. It covers general-purpose or explosion-proof motors with a rated voltage below 1000V (50Hz three-phase AC), rated power from 120W to 1000kW, and 2, 4, 6, or 8 poles. Manufacturers must verify if their specific motor types, including capacitor-start and brushless DC fan motors, fall under this mandatory scope. It references GB/T 755-2019 and GB/T 5171.1-2014 for general performance.
Technical requirements
The standard classifies motor energy efficiency into three grades, where Grade 1 represents the highest efficiency. The minimum allowable values of energy efficiency are defined by the Grade 3 limits. It specifies efficiency requirements for various motor categories, including three-phase asynchronous motors, capacitor-start, capacitor-run, and two-value capacitor asynchronous motors. Additionally, it introduces new efficiency metrics for air conditioner fan capacitor-run motors and brushless DC motors. The measured efficiency at rated output power must strictly meet the corresponding grade limits, with tolerances adhering to GB/T 755-2019 and GB/T 5171.1-2014.
Testing methods
For three-phase asynchronous motors, efficiency must be measured using Method B (loss analysis method of measuring input-output power) as specified in GB/T 1032. For single-phase asynchronous motors and air conditioner fan motors, the direct method outlined in GB/T 5171.21 must be utilized. When testing brushless DC fan motors, the rated speed should be selected as the highest nominal speed indicated on the nameplate.
FAQs
What products are regulated under GB 18613-2020?
It regulates three-phase asynchronous motors, single-phase asynchronous motors, and specific air conditioner fan motors (including brushless DC types) within defined power and voltage ranges.
What is the minimum energy efficiency requirement under this standard?
The Grade 3 efficiency limits serve as the mandatory minimum allowable values. Products must not fall below these Tier 3 limits to be legally sold in China.
Are there updates from the previous version of GB 18613?
Yes, it replaces GB 18613-2012 and GB 25958-2010. Key updates include stricter efficiency limits for three-phase motors, the addition of 8-pole motor grades, and new requirements for air conditioner fan motors.
