Filed:

Jul 1, 2009

Appl. No.:

12/496458

Inventors:

John Stout - Long Beach CA, US
Daniel M. Saban - Corona CA, US
Paulo Guedes-Pinto - Brea CA, US

Assignee:

Direct Drive Systems, Inc. - Fullerton CA

International Classification:

H02K 3/487
H02K 3/24

US Classification:

310214, 310 52

Abstract:

Electric machines with, and related methods for, improved fluid flow through the electric machines are disclosed. According to some implementations, an electric machine may include a central opening and a plurality of teeth facing inwardly toward the central opening. Slots may be defined between adjacent teeth, and a wedge may be disposed in one or more of the slots, partitioning the slots into a coils portion and an open portion. A gap may be defined between the stator core and the rotor. A fluid flow path defined from the gap and the open portions of the slots provide for improved fluid flow through the electric machine. Wedges disposed in the slots to maintain the coils into a packed state.

Daniel M. Saban - Corona CA, US
Paulo Guedes-Pinto - Brea CA, US

International Classification:

H02K 1/16
H02K 15/08
H02K 3/48

US Classification:

310198, 29596, 310208, 310260

Abstract:

A stator for an electric machine includes multiple conductive coils. Each coil defines a loop that extends axially through the elongate core, exits the core through an end face, and reenters the core through the end face. A first subset of the coils collectively form a first radial layer axially exterior the core and a third radial layer axially exterior the core. Each coil in the first subset resides in both the first layer and the third layer. A second subset of the coils collectively forms a second radial layer axially exterior the core and a fourth radial layer axially exterior the core. Each coil in the second subset residing in both the second layer and the fourth layer.

International Classification:

F01D 17/16
F01D 25/16
F01D 15/10
F01D 17/24

Abstract:

An impeller is configured to be rotated by a flowing fluid. A fluid stator includes a fixed ring parallel to a plane of rotation of the impeller. The fixed ring has a center in-line with a center of rotation of the impeller. A rotatable ring is rotatable relative to, and parallel to, the fixed ring. The rotatable ring has a center in-line with a center of rotation of the impeller. Stator vanes extend between the fixed ring and the rotatable ring. The stator vanes define an inlet cross sectional area upstream of the impeller. The cross sectional area is dependent upon a relative position of the fixed ring and the rotatable ring. An actuator is configured to rotate the rotatable ring. An electric rotor is coupled to, and configured to rotate in unison with, the impeller. An electric stator encircles the electric rotor. The electric stator includes coil windings.

E21B 41/00

Abstract:

This disclosure describes various implementations of a downhole-blower system that can be used to boost production in a wellbore. The downhole-blower system includes a blower and an electric machine coupled to the blower that can be deployed in a wellbore, and that can, in cooperation, increase production through the wellbore.

International Classification:

E21B 43/12
F04C 13/00

Abstract:

Certain aspects of the subject matter described here can be implemented in a downhole-type electric submersible pump system. An electric machine can be disposed downhole in a wellbore. The electric machine is coupled to rotate with an impeller that can be disposed downhole in the wellbore. The electric machine includes a stator assembly with at least three stator sections axially arranged and spaced apart from each other along a longitudinal axis of the electric machine. The electric machine also includes a rotor assembly with at least three rotor sections arranged axially along the longitudinal axis of the electric machine. The rotor assembly is carried within and supported to rotate by the stator assembly
