Zusammenfassung:	The present invention relates to a radial fan (1) with an external rotor motor (6+8) and a housing (2), capable of reducing indirect radiation irradiated from a motor. According to the present invention, the radial fan with an external rotor motor comprises: a stator (8) including a plurality of pole pieces (12) and an armature including a stator coil (10); a rotor (8) surrounding the stator from the outside, and including a permanent magnet (7), an external fan blade (3), and a rotor shaft (6) rotatably mounted in the stator; and a printed circuit board (14) spaced apart from the stator coil and having a connection line from the stator coil to operation voltage and ground. At least one conductive connection (18) is connected from a conductive armature (11) of the stator (8) to at least one terminal of the printed circuit board (14) and the terminal is connected to fixed potential (GND, 0, V_CC).
