| 310216011 | Circumferentially offset laminations | 8 |
| 20100327690 | LAMINATED STATOR CORE AND METHOD FOR MANUFACTURING THE SAME - A laminated stator core | 12-30-2010 |
| 20120104894 | AXIAL FLUX PERMANENT MAGNET MACHINE - Permanent magnet synchronous machines ( | 05-03-2012 |
| 20120153769 | ROTOR CORE AND METHOD OF MANUFACTURING THE SAME - A rotor core includes m number of rotor core blocks constituted by stacking annular sheet-like core materials in a direction of sheet thickness of each core material where m is an integer that is 2 or larger than 2, slots circumferentially arranged at regular intervals in an outer circumference of each core material, m number of catch recesses circumferentially disposed in an inner circumference of each core material at an interval obtained by (360÷m)° so as to extend radially outward, the catch recesses having an equal circumferential length and a different radially outward depth. Each rotor core block is constituted by stacking the core materials so that the catch recesses having an identical configuration in the direction of sheet thickness of each rotor core block correspond with one another. Each rotor core block is circumferentially shifted relatively by (360÷m)° from a location where the catch recesses correspond with one another. | 06-21-2012 |

| 20100052466 | ELECTRICAL MACHINE WITH SKEW-RUNNING MAGNET POLE BOUNDARIES - According to the invention, the torque ripple of electrical machines is supposed to be further reduced. For this purpose, it is provided to dispose the magnetic poles, for example, on the surface of a rotor in a plurality of sections (A | 03-04-2010 |
| 20140132108 | ELECTRIC MACHINE, SYNCHRONOUS GENERATOR-FIELD POLE, SYNCHRONOUS GENERATOR-ROTOR COMPRISING A PLURALITY OF FIELD POLES AND METHOD FOR PRODUCING A SYNCHRONOUS GENERATOR-FIELD POLE OF AN ELECTRIC MACHINE - There is provided a synchronous generator rotor pole assembly having a plurality of mutually displaced pole assembly segments which respectively have a plurality of identical pole assembly plates. Each pole assembly plate has a pole shank having a first center line, and a pole head having a second center line. The first and second center lines can be different from each other in adjacent pole assembly segments. | 05-15-2014 |
| 20150303746 | STATOR CORE FOR ROTARY ELECTRIC MACHINE - When a plurality of core plates are stacked and fixed to form a stator core, fixation portions are set in accordance with the relative positional relationship with magnetic poles of a rotor to suppress torque fluctuations. The number of rotational buildup states which is a value obtained by dividing 360 degrees by a rotational buildup angle by which the core plates are rotated in units of a predetermined number of plates to be stacked, the number of magnetic poles which is the number of magnetic poles M of the rotor, and the number of fixation portions which is the number of fixation portions are set such that the number of fixation portions is an integer number of times the number of rotational buildup states and at least common divisors of the number of fixation portions and the number of magnetic poles include “1” only or “1” or “2” only. | 10-22-2015 |
| 20150364955 | STATOR FOR AN ELECTRIC MACHINE - The invention concerns a stator for an electric machine, comprising a plate stack comprising a plurality of superposed stator plates, the plate stack being delimited at the ends by cover plates and an insulating plate being disposed on at least one cover plate in the plate stack, the insulating plate interlocking with the adjacent cover plate. | 12-17-2015 |
| 310216013 | Having axially extended spirally-laminated core | 1 |
| 20120019093 | LAMINATED CORE - A laminated core | 01-26-2012 |
