摘要： A rotating electrical machine is proposed which effectively cools a stator and prevents the generation of an eddy current in the stator. A cooling liquid passage extends in a direction parallel with the rotating shaft of the rotor between an outer peripheral face of the stator cores and an inner peripheral face of the case storing the stator cores. The cooling liquid is passed through the cooling liquid passage. In this manner, a highly effective cooling results from direct contact of the cooling liquid and the stator cores. Furthermore an eddy current is not generated in the stator core as a result of using a cooling liquid having insulating properties.

摘要： A motor or a generator which has permanent magnets on a moveable member effectively reduces eddy current loss in the permanent magnets. A permanent magnet 1 which is provided for the moveable member of a motor or a generator, for example the rotor of a rotating motor, is divided into magnet sections (1A-1E) having divided widths (t1-t5) in response to the rate of change in the flux density in each divided magnet. Thus the eddy current loss in each magnet section (1A-1E) can be substantially equalized.

摘要： An annular member 51 is fitted to the outer periphery of the stator cores in a rotating electric machine. The rotating electric machine has a cooling passage 29 in an axial direction between a resin molded section 50 and adjacent stator cores 20. The annular member 51 is formed from a material which has a larger coefficient of linear expansion than the magnetic material comprising the stator cores. At low temperatures, stress resulting from the differential between the coefficient of linear expansion of the stator core and the resin molded section is reduced because an inward compressive force is applied to the stator core by the annular member as a result of the difference in the coefficient of linear expansion.

摘要： This invention prevents leakage of cooling medium from a cooling passage in the interior section of a slot of a stator. Coils are housed in the slot of the stator core. The openings of the slot are covered in order to form a cooling passage in the slot. An end plate is disposed on the end of the stator. The stator core and the end plate are integrated by winding coils through the outer side of the end plate. A cylindrical member which projects along the inner peripheral face of the stator from the end of the stator is formed by resin molding to be integrated with a section of the end plate. A ring-shaped space which introduces cooling medium is formed on an outer peripheral side of the cylindrical member and is connected with the cooling passage.

摘要： An engine is activated to drive a generator when an electrical output is required. The required electrical output (PO) is searched and the necessary engine output is calculated. The basic driving point (NO, TO) which obtains maximum fuel efficiency is set at that output (S101-S105). The load of the generator is controlled so as to reach the set basic driving point. When the catalyst temperature is lower than a set value, while maintaining the required electrical output, the basic driving point is varied to a driving point (Ncold, Tcold) which will raise the exhaust gas temperature (S106-108). Furthermore when the temperature of the peripheral engine components in the engine room is higher than a set value, while maintaining the required electrical output, the driving point is varied to a driving point (Nheat, Theat) which will lower the exhaust gas temperature (S109-S111). Hence while maintaining the electrical output, it is possible satisfy each component temperature condition. Therefore while maintaining drivability, fuel efficiency performance, lowering exhaust gas emissions and component deterioration can suppressed.

摘要： A hybrid electric vehicle comprises an electric motor, a battery pack for the electric motor, a generator driven by an engine to provide electric power used for charging the battery pack, and a battery management for the battery pack. The battery management determines a current value of battery temperature (BT) of the battery pack and a current value of state of charge (SOC) within the battery pack. What are stored are a first set of varying SOC values and a second set of varying SOC values against varying BT values. The first set of varying SOC values are minimum SOC values required for the battery pack to produce a constant electric power output at varying BT values. The second set of varying SOC values are each indicative of an allowable upper limit to the quantity of electric charge that will accumulate in the battery pack due to operation of charging the battery pack with a constant electric power input at a corresponding BT value. The battery management provide an actuator command for control of electric power input upon charging the battery pack in response to the current value of BT, the current value of SOC, the first set of varying SOC values and the second set of varying SOC values.

摘要： A driving device controls a permanent-magnet synchronous motor having a permanent magnet in its rotor using a voltage-type inverter supplying drive power for the synchronous motor, makes the torque of the synchronous motor and the d-axis current flowing in the synchronous motor in the direction of the magnetic flux generated by the permanent magnet approach their own command values, and performs weakening field control by decreasing the d-axis current. To perform the above described control without complicated d-axis current command value operations or temperature amendments to motor constants, the driving device includes a proportional controller for outputting a d-axis signal proportional to the deviation between a d-axis current detection value and a d-axis current command value for the motor. A d-axis voltage command value and a q-axis voltage command value are determined according to the d-axis signal and a q-axis signal obtained based on the deviation between a q-axis current detection value, which is a component in the direction normal to the magnetic flux, and the torque command value for the motor. A voltage command vector is obtained from the d-axis voltage command value and the q-axis voltage command value. The voltage command vector is PWM-converted and a voltage-type inverter control signal is generated.
