摘要

The invention regards a permanent-magnets mono-phase synchronous electric motor (7) for washing machines and the like, in particular for washing pumps (1), with improved stator (4) structure and of the type centrally comprising a permanent-magnets axial rotor (2) and a stator (4) with a lamination pack core (5) and a couple of pole pieces with ends enveloping the rotor (2), of which they have substantially the same axial length and from which they are spaced by respective aircore. Such a motor is distinguished in that the lamination pack core (5) has a shorter axial length with respect to the ends (10, 11) of said pole pieces.;Advantageously, the stator (4) pole pieces are obtained through moulding magnetic powders.
