These motors comply strictly with GB3836.1-2010 (General Requirements for Equipment in Explosive Atmospheres) and GB3836.2-2010 (Equipment Protected by Flameproof Enclosure "d") standards.
"Ex" indicates the explosion protection mark, "d" stands for the flameproof type, "I" represents the Electrical Apparatus Class (specifically for coal mines), and "Mb" refers to the high Equipment Protection Level (EPL).
It is designed for environments where explosive gas mixtures such as methane or coal dust are present, typically encountered in underground mine operations.
The rated power ranges from 4kW to 1600kW depending on the cooling type, and the available voltage options include 380V/660V, 660/1140V, 1140V, and 3300V at 50Hz.
The motor uses Class 180 (H) insulation with temperature rise ratings of 105K (F) and 135K (H). The ingress protection grade options are IP55 and IP67, ensuring high reliability in harsh environments.
