synchronous electric motor, particularly for pumps and pump immergibili acquiring such an engine

摘要

a synchronous electric motor is formed by a package sheet statorico (2) with at least one winding (6, electric(6) and a rotor (3) in a material with high magnetic retentivitu00e0; thin sheet (4) of the package (2) are arranged in parallel to the axis of the rotor (2) to limit the size of motor cross(1).the package sheet (2) is substantially rectilinear form of the sections (5, 5 ') which are provided for coils (6,6) with axes of the coils substantially parallel to the axis (z) of the rotor (3) and the sheet (4), in correspondence of the sections (5, 5 ').different heights along a transverse direction (x) with respect to the axis (z) of the rotor (3).the package sheet (2) with its windings is drowned in a matrix of resin duct (12).in turn, hermetically sealed within a casing (11) substantially rigid dielectric material forming a modular sealed capsule.the capsule may be coupled to different units rotoriche type to form immergibili pumps.
