Patent ID: 7232292

Claim:
An integrated motorized pump, comprising: (i) an impeller that is mounted on an axle and comprising at least one impeller disk and blades attached to said at least one impeller disk, at least one magnetic drive electro magnetically coupled with an electric motor, and a casing with a flowing space and inlet and outlet channels, wherein: (ii) said impeller being placed inside said flowing space and along with said flowing space, inlet and outlet channels forms pump flowing part; (iii) said impeller having circumferential arrayed magnetic means magnetized in the direction parallel to said axle; (iv) said magnetic drive comprising at least one stator and at least one magnetized disk, wherein: (v) said stator comprising circumferential arrayed coil windings, and said magnetized disk is mounted on said axle and having a circumferential array of radially extending magnetized poles and being mounted perpendicularly to the axle, said magnetized poles of said magnetized disk being spaced axially from the magnetic means of said impeller to form a gap, and at least part of said magnetized poles of said magnetized disk being magnetically opposite to the magnetic means of the impeller, such that the flux lines of the magnetized N poles of said magnetized disk extends to S poles of the magnetic means of the impeller in the shortest axial flux dimension across said gap; (vi) said electric motor comprising said impeller as a rotor, and at least one stator plate; (vii) said stator plate being covered with a liquid tight coating and comprising circumferential arrayed coils etched on circuit board metal layers and said coils being at least partially positioned within said gap between said magnetized disk and said magnetic means, and the number of said coils is divisible in respect to the number of said magnetic means and said magnetized poles; (viii) said casing is rigidly secured with said axle and said stator plate.
