| 310216048 | Having interlamina mating structure on lamina face | 8 |
| 20100219714 | MOTOR AND ELECTRONIC APPARATUS USING THE SAME - A stator core comprises a laminated part made by stacking a plurality of sheet-like plates and one sheet-like plate into an integral unit in a manner to form dimple portions on both surfaces in the stacking direction thereof, and side plates each having extended portions and nib portions formed on a surface opposite the side where the extended portions are provided and disposed in a manner to sandwich the both surfaces of the laminated part, wherein the laminated part and the side plates are fastened together by inserting the nib portions on the side plates into the dimple portions formed on the laminated part. | 09-02-2010 |
| 20120019094 | STATOR CORE AND MOTOR DEVICE INCLUDING THE SAME - Disclosed is a stator core including a core back fixedly inserted onto an outer surface of a stationary member, a plurality of teeth protruding from the core back in an outer diameter direction, wherein a coil is wound around the plurality of teeth so as to allow magnetic flux from a magnet to flow to the teeth, front end portions defining outer edges of the teeth, respectively, and body portions defining a length of the teeth and having a width increasing from the core back toward the front end portions, respectively. | 01-26-2012 |
| 20130134826 | LAMINATE OF METAL PLATES, CORE FOR ROTATING ELECTRICAL MACHINE, AND LAMINATING METHOD FOR LAMINATE OF METAL PLATES - A core is formed by laminating a plurality of core plates. Each of the core plates includes a joint portion for joining the core plates together in the laminated state. Each of the joint portions includes a fixing piece, a passage hole, a receiving portion, and an opening. Each of the fixing pieces is raised in the direction in which the core plates are laminated. Each of the passage holes receives the fixing piece of the corresponding adjacent one of the core plates. | 05-30-2013 |
| 20140015369 | Systems and Methods for Electric Motor Construction - Systems and methods for the construction of electric motors, where multiple laminations within the stator core incorporate interlocking features such as dimples and corresponding depressions or recesses to prevent the laminations from rotating with respect to each other. The end laminations of the stack are welded to snap rings, and the snap rings are welded to the housing to prevent rotation of the laminations within the stator housing. The use of the interlocking features to prevent rotation of the laminations within the housing eliminates the need for compression of the laminations and the use of encapsulants to prevent rotation of the laminations. | 01-16-2014 |
| 20140035429 | STATOR CORE AND MOTOR DEVICE INCLUDING THE SAME - Disclosed is a stator core including a core back fixedly inserted onto an outer surface of a stationary member, a plurality of teeth protruding from the core back in an outer diameter direction, wherein a coil is wound around the plurality of teeth so as to allow magnetic flux from a magnet to flow to the teeth, front end portions defining outer edges of the teeth, respectively, and body portions defining a length of the teeth and having a width increasing from the core back toward the front end portions, respectively. | 02-06-2014 |
| 20140062252 | ROTATING ELECTRIC MACHINE - A rotating electric machine includes a stator and a rotor. The rotor includes a plurality of permanent magnets and a rotor core. The plurality of permanent magnets are to form magnetic poles. The rotor core includes stacked steel sheets, magnet holes, a plurality of cutouts, and fixing elements. The magnet holes are provided in the stacked steel sheets. The plurality of permanent magnets are provided in the magnet holes. The plurality of cutouts are provided between the plurality of permanent magnets located adjacent in a circumferential direction of the rotor core to form different magnetic poles. The fixing elements are to fix the steel sheets to each other. The fixing elements are provided at positions on an outer peripheral side of inner peripheral end portions of the cutouts and between the cutouts and the magnet holes. | 03-06-2014 |
| 20140300243 | ROTOR BLADE SET OF AN ELECTRIC MOTOR - A rotor blade set for an electric motor, having a plurality of axially assembled multi-part and/or single-part blades having circle segment shaped blade sections, between which radial and circumferentially open recesses are formed for receiving a respective magnet, wherein a predeterminable number of blade sections of the single-part or multi-part blades have at least one azimuthal clip on the circle radius, which clip bends axially during the insertion of the corresponding magnet into the respective recess, and wherein the circle segment-shaped blade sections of the single-part or multipart blades have at least one notch on the circle radius, in which notch a corresponding clip of a blade section of an axially spaced blade engages following the axial bending. | 10-09-2014 |
| 20150097462 | LAMINATED CORE AND METHOD FOR MANUFACTURING THE SAME - A laminated core | 04-09-2015 |
