Abstract
An electric motor, particularly for fans for combustion air, or for an air/combustion gas mixture, in gas burners, includes a stator assembly, which in turn includes a lamination pack provided with a perimetric frame with at least one pair of pole shoes, each one of which is constituted by a winding body and an expanded head; a frame for supporting the lamination pack; and a spool of conducting wire for each pole shoe, with the interposition of an insulating support. The assembly further includes elements for reducing rotational friction, for the driving shaft of a rotor, and accommodation parts for the elements for reducing rotational friction. The motor also includes a rotor with a driving shaft, wherein the perimetric frame and pole shoes are mutually distinct elements joined with fixing components.
