This standard is a revision of GB/T50891985 "General Technical Conditions for AC Table Fan Motors", and is renamed "General Technical Conditions for AC Fan Motors". It has been rearranged, combined, appropriately increased and decreased in accordance with the requirements of GB/T1.1-2000, and some changes have been made in the text.
The main differences between this standard and the standard GB/T5089—1985 are: 1. This standard adds the clause "2 Normative references". This standard adds the clause "3 Models, basic parameters and dimensions". - This standard cancels the relevant clauses of "Stalling torque and minimum torque" in the original standard and changes it to "4.7 The motor with corresponding fan blades can start normally at rated frequency, minimum speed gear and 85% of rated voltage." At the same time, other relevant clauses are also cancelled. This standard cancels the relevant clauses of "Speed regulation performance" in the original standard. One standard adds the clause "4.11.4 Turn-to-turn insulation test". One adds the clauses of "5.1 Measuring instruments and measuring tools", "5.2 Inspection of external dimensions and installation dimensions", and "5.6 Determination of radial runout of shaft extension" in the chapter "Test methods". - Adds the clause 6.2.4 of "Qualification determination" in the chapter "Inspection rules". In the chapter "8 Quality assurance period", this standard cancels the sentence "within one year of use of the motor". This standard replaces GB/T 5089-1985 from the date of implementation. This standard is proposed by China Electrical Equipment Industry Association. This standard is under the jurisdiction of the National Technical Committee for Standardization of Rotating Electrical Machines, Small Power Motor Standardization Subcommittee. This standard was first issued on April 26, 1985 and implemented on October 1, 1985. The first revision was in 2003. The main drafting unit of this standard is Guangzhou Electric Science Research Institute. The main drafters of this standard are Yang Zhaote and Lin Tanghua. 1
