摘要 |
The present invention relates to a motor for a submerged pump, wherein said motor comprises a rotor (5) as well as a body (1) having the magnetic conductor (2) of a stator mounted therein. The stator has a dented area (8) comprising grooves (9) in which are arranged the multiple-coil sections of a dual-layer winding having lobe-shaped portions. The magnetic conductor (2) o f the stator comprises two parts (6, 7), i.e. an inner part (6) whose grooves open towards its periphery as well as an outer part (7) forming an annular magnet yoke. Each section of the stator winding has an essentially square cross section and is formed by the coils (12) of a conductor having an essentially rectangular cross section, wherein said coils rest against each other along their large surfaces. The first and second sides of each section are arranged in the various layers (13, 14) of the dual layer winding so tha t in each groove (9) of the winding layers (13, 14), the large surfaces of the coils (12) are mutually perpendicular and so that the lobe-shaped portions have a height not exceeding that of the groove (9). This motor is mainly intended for submerged pumping equipment used in submerged wells.
