GB/T 18211-2017General requirements for safety of electrical micro-machines (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 18211-2000 "General requirements for micro-motor safety," and GB/T 18211-2000 compared to the main technical changes as follows.

--- Modify the definition of creepage distance, clearance two terms (see 3.1 and 3.2, 2000 version 3.1 and 3.2);

--- Added nameplate content (see 4.1);

--- Modify the leakage current parameters and detection time (see 5.1 and 5.2, 2000 version 5.1 and 5.2);

--- Modify the clearance and creepage distances (see Chapter 8, 2000 edition Chapter 8);

--- An increase of electromagnetic compatibility project (see Chapter 18).

1 Scope

This standard specifies the micro-motor safety requirements, including signs, leakage current, dielectric strength insulation, insulation resistance, clearances and creepage Distance, structure, mechanical strength, protective earthing, protection, antirust, dampness, heat deformation, flame retardance, abnormal work, electromagnetic compatibility and inspection rule.

This standard applies to the control of motors and other uses of micromotors (hereinafter referred to as motor) GB/T 7345 provisions.
