| 310216007 | Plural laminated segments radially united | 9 |
| 20100013346 | LOW SPEED, PERMANENT MAGNET BRUSHLESS MOTORS AND GENERATORS - Low speed permanent magnet brushless motors and generators are described that employ an internal or external rotor in a radial form with a high or variable rotor pole to stator pole ratio. The devices incorporate multiple stators joined with parallel connections, which provides high efficiency and variable torque. Methods of construction, materials and uses are presented. | 01-21-2010 |
| 20110309711 | Separable Tooth Tip Armature Construction - In a process of producing a stator forming part of a rotary motor arrangement, a multiplicity of laminations are joined together to produce a first stack of laminations defining teeth, slots between adjacent teeth, and a yoke section connecting the teeth together. Coil elements are then mounted on the teeth so that the coil elements are disposed in the slots between the adjacent teeth, and a second stack of laminations is fitted onto an inner diameter of the first stack of laminations and fixed in place to function as tooth tips. At least part of the second lamination stack is then bored out or otherwise removed to dispose of all but a thin layer of the second stack of laminations bridging adjacent teeth defined by the first stack of laminations. A rotary motor stator produced by such a process is also described. | 12-22-2011 |
| 20120139384 | GENERATOR CORE - A generator core that increases the amount of power generated by a generator is provided. A plurality of magnetic steel sheets including non-divided magnetic steel sheets and divided magnetic steel sheets are stacked on each other to form a plurality of divided cores. The divided magnetic steel sheets are disposed to form a gap portion that crosses a magnetic path in one magnetic steel sheet. Each gap portion is positioned and shaped such that magnetic resistances of magnetic pole portions of the plurality of divided cores are not different from each other. | 06-07-2012 |
| 20130119816 | SEGMENTED MAGNETO-CONDUCTIVE STRUCTURE APPLIED IN ROTATING MACHINES - A segmented magneto-conductive structure applied in rotating machines comprises a rotor assembly and a stator assembly. The rotor assembly includes a rotor yoke component and a plurality of rotor teeth components. The rotor yoke component is made of non-oriented silicon steel. The rotor teeth components are made of grain-oriented silicon steel. The stator assembly includes a plurality of stator yoke components and a plurality of stator teeth components. The stator yoke components and the stator teeth components are made of grain-oriented silicon steel. Thereby, an operational efficiency of a motor applying the segmented magneto-conductive structure is enhanced. | 05-16-2013 |
| 20130200746 | COIL TOOTH ASSEMBLY - A stator back-iron or rotor back-iron of an electric motor, for receiving coil windings comprises a support ( | 08-08-2013 |
| 20130207507 | ROTOR ASSEMBLY FOR MOTOR AND MANUFACTURING METHOD THEREOF - Disclosed herein are a rotor assembly for a motor in which separation type rotor cores having the other polarity are disposed between core members of integral type rotor cores having one polarity and the separation type rotor cores and the integral type rotor cores are fixed to each other using wedges or injection molding materials that are formed of a non-magnetic material, such that movement of magnetic fluxes between the integral type rotor cores and the separation type rotor core may be minimized, and a manufacturing method thereof. | 08-15-2013 |
| 20140042866 | MOTOR CORE COMPONENT AND METHOD FOR INCREASING MATERIAL UTILIZATION AND SLOT FILL RATIO THEREOF - A motor core component ( | 02-13-2014 |
| 20150054378 | INTERLOCKED STATOR YOKE AND STAR FOR ELECTRIC MOTOR - A stator for an electric motor includes a yoke and a star disposed in the yoke. The star is configured to receive a rotor therein and has at least one wire coiled thereat. The yoke and the star are configured such that the star is axially insertable into the yoke with reduced interference and reduced insertion force. The star is axially inserted into the yoke in an unlocked position. When the star is inserted into the yoke, the star is rotatable to a locked position, whereby the star is retained at the yoke via an interference fit. | 02-26-2015 |
| 20160065011 | INDIVIDUAL-SEGMENT ROTOR HAVING INDIVIDUAL SEGMENTS RETAINED BY FLEXURAL SUPPORTS AND PRODUCTION METHOD - The aim is to provide an individual-segment rotor, the construction of which requires low production expenditure. For this purpose, an individual-segment rotor having an axis of rotation and a plurality of laminated core segments ( | 03-03-2016 |
