Title: MOTORISED PUMP WITH AN EMBEDDED ROTOR
Abstract:
The present invention relates to a motorised pump (1) with an embedded rotor, comprising: a casing (10) including a body (11) and a motor jacket (12), a synchronous electric motor (20) that is arranged in the motor jacket (12) and includes a stator (30) and a magnet rotor (40), a shaft (50) that extends along a central axis (X1), and a wheel (60) that has a hydraulic profile adapted for the movement of a fluid (F) in the body (11), the rotor (40), the shaft (50) and the wheel (60) forming a rotary assembly (ER1) freely rotating about the central axis (X1), the stator (30) including a magnetic core, a coil (32) and an encapsulation (34), in which the coil (32) and the magnetic core are embedded, a magnetic gap (22) being radially defined between the coil (32) and the magnets (42), the encapsulation (34) comprising an annular part (35) that surrounds the rotor (40) and a bottom (36) that passes through the central axis (X1), the bottom (36) of the encapsulation (34) being in the shape of a convex bell.
