US Patent:

6744166, Jun 1, 2004
Filed:

Jan 4, 2001
Appl. No.:

09/754537
Inventors:

Bernard G. Harter - Lynnville IN
James A. Wafer - Belleville IL
Donald J. Williams - Pierron IL
Assignee:

Emerson Electric Co. - St. Louis MO
International Classification:

H02K 348
US Classification:

310214, 310215, 310217, 310 71, 310254
Abstract:

A winding end cap assembly for an electric machine with a stator and stator poles includes first and second end caps that are connected to opposite axial end surfaces of one of the stator poles. First and second inner winding retainer sections extend axially to connect an inner end of the first end cap to an inner end of the second end cap. The first and second end caps include an outer section, an inner section and a hub section that connects the outer section to the inner section. The first and second end caps and the first and second inner winding retainer sections define a continuous annular channel that receives and retains winding wire. First and second outer retainer sections connect the first and second end caps adjacent to the outer sections or the hub sections of the first and second end caps.

US Patent:

20020093269, Jul 18, 2002
Filed:

Jan 16, 2001
Appl. No.:

09/761125
Inventors:

Bernard Harter - Lynnville IN, US
Richard Hartsfield - Chesterfield MO, US
James Wafer - Belleville IL, US
International Classification:

H02K001/12
H02K001/14
US Classification:

310/254000, 310/216000
Abstract:

A stator for an electric machine such as a motor or a generator includes a plurality of stator segment assemblies. The stator segment assembly includes a stack of stator plates forming a stator segment core. The stator plates include an outer rim section and a tooth section that extends radially inwardly from a center portion of the outer rim section. A radially inner surface of the outer rim section is generally perpendicular to the tooth section. Undercut portions are formed in the radially inner surface of the outer rim section adjacent to the center portion. The undercut portions increase slot area and allow additional winding wire to be wound around the stack. The additional winding wire increases the current carrying capacity of the electric machine through reduced resistance or increased torque per unit volume.

US Patent:

6040647, Mar 21, 2000
Filed:

Dec 18, 1998
Appl. No.:

9/216328
Inventors:

Cary Lee Brown - Evansville IN
Richard C. Hartsfield - Chesterfield MO
Bernard Gerald Harter - Lynnville IN
Brian Schoolcraft - Statesville NC
Assignee:

Emerson Electric Co. - St. Louis MI
International Classification:

H02K 500
US Classification:

310 89
Abstract:

An electromagnetic device, such has an electric motor, having a stator with a stator bore having a center axis that is precisely aligned with the center axes of the rotor and bearings supporting the rotor, self-broaching pins in endbells of the motor which align the stator bore with shaft openings of the endbells and radial spokes in the endbells that allow communication from the endbells into the stator enclosure to permit the injection of encapsulating resin into and through the endbells into the stator enclosure where the encapsulant permeates the stator assembly and secures the endbells to the stator.
