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.

This document replaces GB/T 25441-2010 "Vacuum Cleaner Motor". Compared with GB/T 25441-2010, except for structural adjustment and editorial Besides the changes, the main technical changes are as follows.

--- Added the definition of controller and counter electromotive force constant (see 3.9, 3.10);

--- Changed the range of rated parameters (see 4.2, 4.3 of the 2010 edition);

--- Added brushless DC motor performance parameters (see 5.4);

---Changed performance indicators such as maximum suction power, maximum vacuum degree, maximum air volume, maximum efficiency (see 5.4, 5.12 of the 2010 edition);

--- Added technical requirements for brushless DC motors (see 5.4, 5.7, 5.8, 5.10, 5.11, 5.12 and 5.13);

---Deleted the original standard safety item, changed to refer to GB/T 12350-2022 (see 5.9, 5.10, 5.11, 5.13, 2010 edition 5.15, 5.17 and 5.20);

--- Added counter electromotive force constant, controller protection function, reliability requirements and test methods (see 5.10, 5.11, 5.13, 6.10, 6.11 and 6.13).
