Articulated motor stator assembly for a pump

The motor stator assembly of claim 15, wherein the stator windings are non-overlapping.

A pump for pumping a flow of blood therethrough, the pump having an electric motor comprising a cylindrical stator assembly and a rotatable rotor assembly disposed within the stator assembly, the stator assembly having multiple, non-overlapping windings disposed within corresponding azimuthal sections of the stator assembly;

• the azimuthal sections of the stator assembly being mechanically connected along at least one axially directed pivot, and by a manually operable locking mechanism between any adjacent two of the azimuthal sections, to form a cylindrical structure defining a central aperture within which the rotor is adapted to rotate in response to electrical activity in the stator windings;
• the azimuthal sections of the stator assembly being mechanically separable, by manually releasing the locking assembly, for removal and installation of the rotor assembly.

An articulating motor stator assembly, comprising multiple azimuthal sections positionable in parallel to form a cylindrical structure with each azimuthal section extending the length of the structure;

• the sections mechanically coupled by at least one hinge pivotable about an axis extending along the length of the cylindrical structure;
• the sections each containing a respective electrical winding for receiving electrical current to drive a motor rotor assembly positioned within the cylindrical structure;
• the stator assembly further comprising a manually operable locking mechanism releasably connecting two adjacent azimuthal sections and adapted to be released to enable articulation of the stator assembly for insertion and removal of the rotor assembly.
