Particularly for fans for combustion air or air / combustion gas mixtures of gas burners, stator assemblies for such electric motors, and assembly methods for such stator assemblies

摘要

In particular, the electric motor 10 for fans for the combustion air or air / flue gas mixture of gas burners comprises: a stacked pack (10) provided with an outer frame (13) with at least one pair of pole shoes Each of the pole shoes being constituted by a winding body 16 and an extended head 18 and a frame 20 for supporting the stacked pack 12, Spools 21 and 22 of a conductive wire for each pole shoe 14 and 15 interposed between the drive shafts 26 and 23 of the rotor 25; - a stator assembly (11) comprising receiving parts (27, 28) for the means for reducing said rotational friction; And a rotor (25) having a drive shaft (26). The electric motor being characterized in that the outer frame (13) and the pole shoes (14, 15) are separate elements joined by a securing means (29); - each insulator support (23, 24) is constituted by annular bodies (30, 31) with perforation shaft openings (32, 33) which are contoured to surround the corresponding winding bodies (16, 17); Characterized in that the support frame (20) for the laminate pack (12) is interlocked between the outer frame (13) of the pack (12) and the insulation supports (23, 24) do.
