摘要： A change in torque produced by a motor having two rotors is reduced when the motor operates in a low-velocity and low-torque operational state. The motor has a first rotor and a second rotor, each of which has a permanent magnet, and an output shaft capable of rotating integrally with the first rotor. The second rotor can relatively rotate with respect to the first rotor by a driving force from a phase difference changing driving device, and the phase difference between the rotors (rotor phase difference) can be changed by the relative rotation of the second rotor with respect to the first rotor. When the values of the torque and the rotational velocity of the motor lie within a predetermined region in the proximity of 0, the phase difference changing driving device adjusts the rotor phase difference to a predetermined phase difference for which the strength of a composite field of the permanent magnets is lower than a maximum strength.

摘要： This electric motor includes first permanent magnets secured integrally to an outer periphery side rotor and second permanent magnets secured integrally to an inner periphery side rotor. The first permanent magnets and the second permanent magnets are arranged so as to offset the relative torque produced between the outer periphery side rotor and the inner periphery side rotor based on the magnetic flux of the inner peripheral permanent magnets and the outer peripheral permanent magnets.

摘要： An outer rotor type brushless direct current motor has an outer rotor including a plurality of permanent magnets attached along the inner circumference of an annular yoke such that the magnetic poles face the S magnetic poles. Thin sections are formed by chamfering the radially outer periphery of the two end sections in the circumferential direction of each of the permanent magnets. Magnetic flux passage sections of the yoke providing connection between the thin sections of adjacent permanent magnets are expanded radially inwards. In accordance with the above-mentioned arrangement, the cross section of the magnetic path in the magnetic flux passage sections is increased, thereby suppressing the occurrence of magnetic saturation and preventing the maximum torque of the permanent magnets from decreasing while reducing their size. Moreover, because the magnetic flux passage sections of the yoke are expanded radially inwards, the external dimensions of the yoke do not increase.

摘要： A system for automatically stopping and starting an engine of a vehicle which enables proper determination of whether the stopping of the engine is possible, in accordance with the state of a battery. A power brought out from the battery by auxiliaries is subtracted from a power generated by a generator, thereby calculating a difference corresponding to a power for actually charging the battery. By sequentially adding the value, an integrated value of power charged in the battery is calculated. Meanwhile, a value of a known power WBRK consumed by a brake lamp plus a current power consumed by the auxiliaries is multiplied by a beforehand determined target value of idling-stoppage duration, thereby evaluating an evaluated integrated value of power consumed by the battery during stoppage of an idling. If the integrated value is not less than the evaluated integrated value, the stopping of the engine E is permitted.

摘要： An information control device for an electric vehicle including a vehicle-mounted battery that is charged with electric power supplied from a power supply provided at an outside of the vehicle includes a lock operation detector, a remaining power detector, and a notification controller. The lock operation detector is configured to detect a lock operation of a door lock mechanism of the vehicle. The remaining power detector is configured to detect a remaining power amount of the vehicle-mounted battery. The notification controller is configured to control a notifying device to make a notification to the outside of the vehicle. The notification is indicative of information that recommends power charge of the vehicle-mounted battery if the remaining power amount is small when the door lock mechanism has been locked or is to be locked, based on detection results of the lock operation detector and the remaining power detector.
