Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents" Drafting is required.

This document replaces GB/T 13537-2009 "General Technical Requirements for Electric Motors for Electronic Household Appliances" and is consistent with GB/T 13537-2009.

In addition to structural adjustments and editorial changes, the main technical changes are as follows.

Changed the scope (see Chapter 1, Chapter 1 of the 2009 edition);

Added terms and definitions (see Chapter 3);

In the "Power Frequency and Voltage Level Classification", three voltage levels, "140, 280, 310", are added to the "DC" type.

The voltage level "110" has been deleted from the "AC" type (see Table 1, Table 1 of the 2009 edition);

Increased heat resistance level (see 4.4);

The technical requirements for appearance and assembly quality have been changed (see 5.1.1, 4.1.1 of the 2009 edition);

The technical requirements and test methods for radial runout of shaft extension have been changed (see 5.5, 4.4 of the 2009 edition);

The coaxiality of the mounting mating surface and the perpendicularity of the mounting mating end surface have been changed (see 5.6, 5.7, 4.5 of the 2009 edition);

Modified insulation resistance and insulation dielectric strength (see 5.9, 5.10, 4.8, 4.9 of the 2009 edition);

Added leakage current technical requirements and test methods (see 5.11);

Added technical requirements and test methods for creepage distance and electrical clearance (see 5.12);

Added technical requirements and test methods for protection level (see 5.13);

Added "efficiency" [see 5.15.1.2d), 5.15.1.3e)];

The technical requirements for rated data have been changed (see 5.15.1.4, 4.11.1.4 of the 2009 edition);

Added technical requirements and test methods for pull-out torque (see 5.16);

The technical requirements and test methods for the mechanical strength of lead wires have been changed (see 5.23, 4.18 of the 2009 edition);

The technical requirements and test methods for noise have been changed (see 5.25, 4.21 of the 2009 edition);

The values for copper windings and aluminum windings in the temperature rise test method have been changed (see 5.26.2, 4.22.2 of the 2009 edition);

Changed the technical requirements and test methods for low temperature storage, low temperature operation, high temperature storage, and high temperature operation (see 5.27, 5.28, 4.23 and 4.24 of the 2009 edition);

Changed the technical requirements and test methods for electromagnetic compatibility (see 5.31, 4.28 of the 2009 edition);

Added technical requirements and test methods for thermal shock, free fall, shaft electrical corrosion, and salt spray (see 5.30, 5.34, 5.35, 5.36);

The reliability index of life span has been changed (see Table 5, Table 5 of the 2009 edition);

The technical requirements and test methods for packaging testing and safety have been changed (see 5.39, 5.40, 4.30, 4.31 of the 2009 edition);

The inspection items and order have been changed (see Table 6, Table 6 of the 2009 edition).
