20080289891 | Mounting structure of part - A breather device provided on the outer peripheral section of a case of an in-wheel motor is located at a position above the rotation shaft of the in-wheel motor, between the in-wheel motor and a wheel. The position is inside the wheel in the width direction of a vehicle. | 11-27-2008 |
20090025991 | Electrically Driven Wheel and Vehicle - An electrically driven wheel includes a wheel disc and a wheel hub; an in-wheel motor mounted within the wheel disc to drive the wheel disc and the wheel hub or to be driven by the wheel disc and the wheel hub; a brake rotor and a brake caliper suppressing rotation of the wheel disc and the wheel hub while a vehicle is moving; and a parking lock mechanism provided in the in-wheel motor separately from a brake mechanism formed of the brake rotor and the brake caliper. The parking lock mechanism is a band-type brake frictionally engaging a planetary carrier serving as an “output portion” of a “reduction mechanism”. | 01-29-2009 |
20090038865 | Cooling Structure for In-Wheel Motor - A cooling structure for an in-wheel motor includes an in-wheel motor mounted within a wheel of a vehicle to drive the wheel or to be driven by the wheel, and an oil channel and a fin serving as “heat radiating portions” to facilitate cooling of the in-wheel motor. The in-wheel motor has a case serving as a “housing”. The “heat radiating portion” is located apart from the case. | 02-12-2009 |
20090088914 | Driving Power Control Apparatus for Four Wheel Drive Vehicle - Front left and right wheel units (FL, FR) are driven by an engine (ENG) and a motor generator (MG | 04-02-2009 |
20090121577 | Stator core, motor, and method of manufacturing stator - A stator core installed around the rotating shaft of a motor, comprising a plurality of split cores split in the circumferential direction. The split core is formed of a compressed powder magnetic core. To connect the split core to the adjacent split core, hole parts of rectangular parallelepiped shape are formed in the upper end surfaces thereof. A connection between the split cores is performed by press-fitting a clamp into the hole parts. As a result, the split stators can be compactly integrated with each other. | 05-14-2009 |
20090121820 | Core and method for producing core - Disclosed is a highly heat-resistant core which has a dust core as a base body. A dust core obtained by press-molding magnetic powder particles particles each of which are covered with an insulating film is used as the base body. An inorganic heat-resistant insulating film is formed on at least a part of a surface of the dust core which faces a winding wire. | 05-14-2009 |
20100004090 | DRIVING FORCE CONTROL APPARATUS FOR A VEHICLE THAT DRIVES WHEEL UNITS INDEPENDENTLY - Right front wheel units (FL, FR) are driven independently by motor generators (MGL, MGR). A power control unit ( | 01-07-2010 |
20100019606 | ROTATING ELECTRIC MOTOR - A rotating electric motor includes a stator core, a rotational shaft capable of rotation, a field yoke allowing a flow of magnetic flux in an axial direction, first and second rotor cores fixedly installed on the rotational shaft, a first magnet fixedly installed between the first rotor core and the second rotor core, a first rotor teeth formed at the first rotor core, a second magnet provided alongside of the first rotor teeth in the circumferential direction of the first rotor core, a second rotor teeth formed at the outer surface of the second rotor core, protruding outwardly in the radial direction, a third magnet provided alongside of the second rotor core in the axial direction, and windings that can control the density of magnetic flux between at least one of the first rotor core and second rotor core and the stator core. | 01-28-2010 |
20100071971 | DRIVE DEVICE OF ELECTRIC MOTOR - An electric motor ( | 03-25-2010 |
20100072865 | VEHICLE DRIVE DEVICE - A vehicle drive device includes a motor generator (MG | 03-25-2010 |
20100075218 | BATTERY UNIT - A battery unit includes a casing, bipolar batteries as a plurality of stacked type batteries housed in the casing, and a plug. The bipolar battery is formed by stacking a plurality of battery elements each having sheet electrodes on opposite sides of an electrolyte, and has collectors. The plug is detachably inserted between the bipolar batteries, and electrically connects bipolar batteries. | 03-25-2010 |
20100156204 | Stator core, motor using the stator core, and method of manufacturing the stator core - A stator core includes a pressurized powder core section which is produced by compression-molding a magnetic powder covered by an insulation coating. At least a portion of the pressurized powder core section forms at least a part of a winding slot section around which a winding is wrapped. The pressurized powder core section comprises a winding guide groove which prevents the winding from deviating along the extending direction of the winding slot section. As a result, a space factor of the winding can be increased, to thereby further improve motor output. | 06-24-2010 |
