20080272663 | MAGNETO ROTOR - A magneto rotor in which a plurality of magnets are secured on an inner periphery of a peripheral wall portion of a cup-like rotor yoke, and a magnet protecting cover is provided that integrally has a cylindrical portion that covers inner peripheries of the magnets, and an outer flange that is formed at one axial end of the cylindrical portion and covers end surfaces of the magnets, wherein an annular protrusion protruding toward the opening of the rotor yoke is formed on an area closer to an inner periphery of the outer flange of the magnet protecting cover, an annular adhesive storage portion is formed between the peripheral wall portion closer to the open end of the rotor yoke and the annular protrusion, a groove opening into the adhesive storage portion and continuing circumferentially of the rotor yoke is also formed in the peripheral wall portion closer to the open end of the rotor yoke, and the adhesive storage portion and the groove are filled with an adhesive to seal a boundary between the outer flange of the magnet protecting cover and the peripheral wall portion of the rotor yoke with the adhesive. | 11-06-2008 |
20080278016 | ROTOR OF MAGNETO GENERATOR - In a rotor of a magneto generator in which permanent magnets are attached to the inner circumference of a peripheral wall of a cup-shaped formed flywheel, and a plurality of trigger poles are arranged on the outer circumference of the flywheel; the plurality of trigger poles are simultaneously punched out by press working to form a protrusion ring which is formed of a separate member from the flywheel, and the protrusion ring is integrally incorporated to the flywheel to configure the rotor. | 11-13-2008 |
20090134728 | MAGNETO GENERATOR - A magneto generator can reduce the man-hours of processing and an amount of use (i.e., an amount of material) of permanent magnets used per generator. The magneto generator includes a bowl-shaped flywheel that rotates about an axis of rotation, a plurality of permanent magnets that are fixedly secured to an inner peripheral wall surface of the flywheel, a stator core that is arranged at an inner side of the permanent magnets and has a plurality of teeth protruding to a radially outer side, and magneto coils that are formed of conductors wound around the teeth, respectively. Each of the permanent magnets is composed of a plurality of magnet pieces that are formed by dividing a hexahedral magnet main body with a division surface extending in a radial direction. | 05-28-2009 |
20090174271 | Combined generator with built-in eddy-current magnetic resistance - A combined generator with built-in eddy-current magnetic resistance including a rotor and a stator iron core with generating coils winding therearound. The rotor consists of an outward turning type inertia flywheel and permanent magnets. A self-generated supply is achieved when the flywheel is driven by a fitness apparatus or a rehabilitation apparatus. An internal ring (A magnet-conductive ring) between the wheel hub and the external ring of the flywheel is extended from the internal wall toward the opening end. The internal diameter of the stator iron core is greater than the external diameter of the magnet-conductive ring such that a magnetic field gap is created. At least one receiving portion is formed in at least one portion of the internal circumference of the stator iron core for receiving at least one solenoid. The power required by the solenoid is supplied by the self-generated system such that the solenoid produces a magnetic field (by input of the power), thereby providing the magnet-conductive ring coupled to and rotated on the inertia flywheel with an eddy-current magnetic resistance. In this way, a reverse resistance acts from the inside on the inertia flywheel such that a braking effect is achieved. | 07-09-2009 |
20100072847 | Electromagnetically Driven Configuration of Flywheels And Rotors To Power Zero Emission Vehicles - An electric vehicle drive system includes an improved mechanical flywheel, rotor and friction disc assembly comprised of a plurality of coaxial flywheels, friction discs and rotors being driven by electromagnets placed on the outer circumference of the assembly containment ring and interspersed on the outsides of the assembly end plates. | 03-25-2010 |
20140125178 | MAGNETIC ELECTRICAL GENERATOR - A magnetic electrical generator includes a rotational device that rotates a flywheel. The flywheel includes a plurality of magnetic elements that are arranged to alternate in polarity. The plurality of magnets is rotated in between a top and a bottom of at least one pole piece, which creates an alternating B field that is coupled to a pickup coil. | 05-08-2014 |
20140333167 | MAGNET-TYPE ROTATING ELECTRIC MACHINE - There is provided an alternating current generator for a vehicle, including: a rotor ( | 11-13-2014 |
