| 310216066 | Homogeneous core or yoke (e.g., solid core) | 8 |
| 20100289375 | Stator Core - A stator core includes a magnetically conductive member coated with an insulating layer. The magnetically conductive member is integrally formed as a single continuous monolithic piece. The magnetically conductive member includes a ring, a plurality of pole teeth, and a plurality of magnetic pole portions. The ring has an inner periphery defining a compartment. Each pole tooth includes a first end contiguous to the inner periphery of the ring and a second end extending in the compartment. Each magnetic pole portion is contiguous to the second end of one of the pole teeth. The stator core can be utilized to form a stator for an inner rotor motor. Each pole tooth can include arcuate guide portions to allow easy winding of coils. | 11-18-2010 |
| 20110050027 | Motor Rotor - A motor rotor includes a magnetically conducting member having an inner periphery and an outer periphery spaced from the inner periphery in a radial direction. The magnetically conducting member further includes first and second ends spaced along an axis perpendicular to the radial direction. The magnetically conducting member includes a reinforcing portion extending from the first end in the radial direction. A rotatable member is formed by injection molding and embraces and engages the outer periphery of the magnetically conducting member. The rotatable member includes an opening receiving the first end of the magnetically conducting member and is rotatable about the axis. A permanent magnet is coupled to the inner periphery of the magnetically conducting member. The reinforcing portion reinforces the first end of the magnetically conducting member, which is useful during injection molding of the rotatable member. | 03-03-2011 |
| 20110204744 | ROTOR CORE AND ELECTRIC MOTOR - A rotor core includes a body made of a soft magnetic material powder, the body being rotatable about a predetermined rotation axis; plural arms formed integral with the body from the soft magnetic material powder, the arms projecting toward an outside of the body in a diameter direction of the body and being provided with a coil; and salient poles formed integral with the arms from the soft magnetic material powder, the poles being mounted at the side of the respective arms reverse to the body. | 08-25-2011 |
| 20130342069 | IRON OXIDE AND SILICA MAGNETIC CORE - A magnetic core of superparamagnetic core shell nanoparticles having a particle size of less than 50 nm; wherein the core is an iron oxide and the shell is a silicon oxide is provided. The magnetic core is a monolithic structure of superparamagnetic core grains of iron oxide directly bonded by the silicon dioxide shells. A method to prepare the magnetic core which allows maintenance of the superparamagnetic state of the nanoparticles is also provided. The magnetic core has little core loss due to hysteresis or eddy current flow. | 12-26-2013 |

| 20100225195 | Armature Core, Motor Using It, and Its Manufacturing Method - An object is to enable simple manufacture of a motor, especially, a stator core or a field without impairment of motor characteristics. The motor includes a shaft, a rotor fixed to the shaft, and a stator including a stator core that faces the rotor with a certain space therebetween and coils that are attached to the stator core. The stator includes a back yoke, and the stator core having a plurality of teeth that are circumferentially placed in an axial end face of the back yoke so as to stand upright axially of the back yoke, and that are formed of a dust core made of pressed magnetic powder. The above-mentioned teeth are buried axially to a certain depth in the back yoke. | 09-09-2010 |
| 20140265716 | SOFT MAGNETIC CORE AND MOTOR INCLUDING THE SAME - There is provided a soft magnetic core including: soft magnetic powder particles having an insulating coating layer formed on surfaces thereof and metal powder particles positioned between the soft magnetic powder particles. | 09-18-2014 |
| 20160133364 | Fixtures and Methods for Forming Aligned Magnetic Cores - Magnetic cores and method and fixtures for forming the same are disclosed. The magnetic core may comprise a magnetic body including magnetic grains and a magnetic flux path, the magnetic grains aligned in a plurality of distinct directional alignments to conform to the magnetic flux path. The grain orientation of the cores may be provided by fixtures including electrical circuits and/or permanent magnets. The fixtures may be configured to produce magnetic fields that approximate, mimic, or correspond to a magnetic flux path in the magnetic core, once it is consolidated and in use. The magnetic fields may orient the grains of the magnetic core when they are in an unconsolidated state, such that the grains are aligned in a plurality of directional alignments that approximate, mimic, or correspond to a magnetic flux path in the magnetic core. | 05-12-2016 |
