Introduction
GB/T 5089—2017 Standard Overview
GB/T 5089—2017 is a national standard of the People's Republic of China, entitled "General Technical Requirements for Electric Fan Motors". This standard replaces the old version of GB/T 5089—2008, and is mainly applicable to AC capacitor-operated asynchronous motors, shaded-pole asynchronous motors and permanent magnet brushless DC motors used in electric fans. Electric fan motors refer to the head part above the connector except the connecting rod, outer cover, mesh cover, and fan blades (wings).
Main changes and technical evolution analysis
- Scope of application expansion: New technical requirements for permanent magnet brushless DC motors have been added, reflecting the development trend of industry technology.
- Update of normative reference documents: The latest relevant standards and test methods have been adopted.
- Newly added recommended optimal values: Added recommended optimal values for parameters such as fan blade diameter and input power to facilitate product selection.
- Optimized technical requirements: Modified motor speed, noise limit and power factor requirements to improve product quality.
Comparison of Standard Frameworks
| Standard Dimensions | GB/T 5089—2008 | GB/T 5089—2017 |
|---|---|---|
| Scope of Application | Limited to AC fan motors | Covering AC and permanent magnet brushless DC motors |
| Technical Requirements | Power factor and speed ratio requirements are not specified | New power factor guarantee value and speed ratio limit are added |
| Test Methods | Specific requirements are not specified for some tests | Cited GB/T 5171 series standards specify the test methods and parameters |
Implementation recommendations and precautions
Case analysis: How to choose a suitable motor?
When selecting a motor for an electric fan, the selection should be based on the specific application scenario and performance requirements. For example:
- AC capacitor-operated asynchronous motor: Suitable for scenarios requiring higher efficiency and stable speed.
- Shaded-pole asynchronous motor: Suitable for applications with simple control and low noise requirements.
- Brushless DC motor: Suitable for occasions requiring high-precision speed regulation and long life, such as high-end electric fans and ceiling fans.
