DIRECT CURRENT ELECTRIC MOTOR IN AN EXPLOSION PROOF DESIGN

摘要

The invention relates to a direct current electric motor having a stator (1) comprising motor windings (28), and a rotor (2) which encloses said stator and is designed as an external rotor, as well as a motor housing (3) consisting of a terminal box section (C) and of a motor section (A) comprising a rotor (2) and a stator (1) as well as of an electronics housing section (B) arranged between the motor section (A) and the terminal box section (C), wherein a motor electronics unit (34) is arranged in the interior (4) of said electronics housing section. The electronics housing section (B) which holds the motor electronics unit (34) has an explosion proof design according to the EU Guideline 94/9/EU in accordance with II 2G Ex d e, the interior (4) of which forms a pressure resistant encapsulation according to EN 60079-1. The other motor sections (A, C) are designed as areas with increased safety according to EN 60079-7.
