20100051363 | AUTOMOTIVE HYBRID ENGINE ASSIST SYSTEM - An automotive hybrid engine assist system that simultaneously mounts both an idling reduction system and an electric motor turbocharging system, and that is small, light, inexpensive, and fuel-efficient. Three-phase power terminals of a generator-motor and a super-high-speed rotary machine are respectively connected to an inverter by a large-current wiring. An electric power direction change-over switch is disposed in a path of the large-current wiring, and switches connection of the inverter to the generator-motor or to the super-high-speed rotary machine. | 03-04-2010 |
20100250184 | ROTATION ANGLE DETECTION APPARATUS - An arithmetic processing means detects a change in a rotation angle of one or more rotations from the direction of a change in the sign of one of sensor output signals and the sign of the other sensor output signal, and generates multiple rotation angle information from information about the detected change in the rotation angle of one or more rotations and rotation angle information about one rotation calculated from the sensor output signals. | 09-30-2010 |
20110058967 | MAGNETIC INDUCTOR ROTARY MACHINE AND FLUID TRANSFER APPARATUS THAT USES THE SAME - A high-efficiency magnetic inductor rotary machine in which eddy current loss is reduced even if driven at super-high-speed rotation, and a fluid transfer apparatus that uses the same. In the magnetic inductor rotary machines, first and second stator cores are disposed coaxially such that circumferential positions of teeth are aligned, and first and second rotor cores are fixed coaxially to a rotating shaft such that salient poles are offset by a pitch of half a salient pole circumferentially, and are disposed on an inner peripheral side of the first and second stator cores. A salient pole width of the salient poles of the first and second rotor cores is configured so as to be greater than an opening width of slots of a stator. | 03-10-2011 |
20110070108 | ROTARY ELECTRIC MOTOR AND BLOWER THAT USES THE SAME - In a rotary electric motor a first stator core and a second stator core are disposed coaxially so as to be separated by a predetermined distance axially and such that circumferential positions of teeth are aligned, and a first rotor core and a second rotor core on which salient poles are disposed at a uniform angular pitch circumferentially are fixed coaxially to a rotating shaft so as to be positioned on inner peripheral sides of the first stator core and the second stator core, respectively, and so as to be offset circumferentially by a pitch of half a salient pole from each other. A first permanent magnet that is magnetically oriented such that a direction of magnetization is radially inward is disposed on an outer peripheral surface of a core back of the first stator core, and an outer peripheral surface of the first permanent magnet and the outer peripheral surface of the core back of the second stator core are linked by a frame that is made of a magnetic material. | 03-24-2011 |
20110273127 | VALVE CONTROL DEVICE - In opening/closing control for the valve mechanism to which the return torque is applied in an opening direction or a closing direction of the valve, provided are a position control system for outputting a q-axis current command based on a position deviation between a target position command directed to the brushless DC motor and the coarse present position of the motor obtained by using the position detection sensor of a pulse output type, and a current control system in which a virtual current feedback is built for outputting a phase voltage command without a current sensor based on the q-axis current command and the coarse present position of the motor obtained by using the position detection sensor of the pulse output type. | 11-10-2011 |
20130192419 | ENGINE STARTING DEVICE - An engine starting device includes: a starter motor; a pinion unit coupled to an output-shaft side of the starter motor by a spline, for sliding in an axial direction; and a ring gear which meshes with a pinion gear of the pinion unit pushed out by a push-out mechanism, and receives a transmission of a rotation force of the starter motor, thereby starting an engine. The pinion unit includes, on all teeth on distal end portions in a meshing axial direction of the pinion gear meshing with the ring gear, synchronization surfaces which are a pair of surfaces parallel with the meshing axial direction, and have a thickness thinner than a tooth thickness of the pinion gear. | 08-01-2013 |
