摘要： A controller for motor/generators is proposed which allows reductions in ripple current generated by an inverter driving a power-generating motor/generator and a vehicle-driving motor/generator. The control device for motor/generators has a first inverter which supplies a control current to a first motor/generator used mainly as an electrical motor, a second inverter which supplies a control current to a second motor/generator used mainly as a generator, a first PWM signal generating circuit which drives the switching elements of the first inverter based on a first carrier signal, a second PWM signal generating circuit which drives the switching elements of the second inverter based on a second carrier signal which has the same period of the first carrier signal. The first inverter and the second inverter are controlled so that the operation of the first inverter is synchronized with the operation of the second inverter and the current of the first inverter which flows in the DC bus line is generated in opposite direction to the current of the second inverter which flows in the DC bus line.

摘要： A rotating electric machine using an inner section of a slot of a stator as a cooling passage obtains highly effective cooling performance with a small amount of cooling medium. An opening for a slot in a stator is closed by an under plate having a closing member. A regulating plate is disposed which is a member for regulating the cross-sectional area of the passage in substantially a central section of the slot. In this manner, the cross-sectional area of the cooling passage with the plate in the slot is smaller than the cross-sectional area when the regulating plate is not provided by an area corresponding to the cross-sectional area of the regulating plate. This arrangement allows increases in cooling efficiency.

摘要： A rotor (11) for a synchronous motor is provided with a plurality of magnets (15) being substantially V-shaped in cross-section. The V-shaped cross-section is defined by an inner V-surface (25), an outer V-surface (19) and an outward face (23) facing outwardly. A first angle &agr; is subtended between a first straight line connecting a point of intersection (31) of the outer V-surface (19) and the outward face (23) and a second straight line connecting the center (35) of the rotor (11) and the acute angle point (27). A second angle &bgr; is subtended between the first straight line and a third straight line connecting a point of intersection (33) of the inner V-surface (25) and the outward face (23). By setting the angle &bgr; to be larger than 20 percent of the angle &agr;, leakage flux at both ends of the magnets (15) is reduced.

摘要： A cooling structure and a rotating electric machine with the cooling structure are provided. The cooling structure produces sufficient reductions in the temperature of the stator core while at the same time not causing a large reduction in the output of the rotating electric machine. The rotating electric machine is provided with a first cooling medium passage formed in the slot. In addition, a second cooling medium passage is provided which extends in parallel to the first cooling medium passage and allows flow of the same cooling medium as the first cooling medium passage. The stator core comprises at least a section of the passage wall of the second cooling medium passage. The second cooling medium passage is disposed so that the second cooling medium passage does not impede the flow of magnetic flux in the stator core.

摘要： This invention provides a rotating electric machine using an inner section of a slot of a stator as a cooling passage and allowing a high cooling efficiency. Furthermore, it provides a manufacture method for the rotating electric machine which allows streamlining of the manufacture of the cooling passage. A plate is attached to the plate retaining groove formed in proximity to the opening of the slot of the stator. A resin layer is formed by injection of resin into a space formed between the outer face of the plate and the mold set on an inner peripheral face of the stator. The plate is pressed by the injection pressure of the resin to come into close contact with the stopper and to create a seal which prevents leakage of resin into the slot. A leg is provided on the plate and extends into the slot for reducing the cross sectional surface area of the cooling passage.

摘要： A first inverter circuit (3A) and a second inverter circuit (3B) are formed on a substrate (25). The first inverter circuit (3A) outputs a first three-phase alternating current generated by a first group of switching elements (SW1, SW2, SW3, SW4, SW5, SW6) via a first output busbar (28UA), a second output busbar (28VA), and a third output busbar (28WA). A second inverter circuit (3B) outputs a second three-phase alternating current generated by a second group of switching elements (SW7, SW8, SW9, SW10, SW11, SW12) via a fourth output busbar (28UB), a fifth output busbar (28VB), and a sixth output busbar (28WB). The fourth output busbar (28UB) is in close proximity to the first output busbar (28UA), the fifth output busbar (28VB) is in close proximity to the second output busbar (28VA) and the sixth output busbar (28WB) is in close proximity to the third output busbar (28WA). The first group of switching elements (SW1, SW2, SW3, SW4, SW5, SW6) and second group of switching elements (SW7, SW8, SW9, SW10, SW11, SW12) are arranged so that the direction of the current in the fourth output busbar (28UB) is opposite to the direction of the current in the first output busbar (28UA), the direction of the current in the fifth output busbar (28VB) is opposite to the direction of the current in the second output busbar (28VA), and the direction of the current in the sixth output busbar (28WB) is opposite to the direction of the current in the third output busbar (28WA).

摘要： A battery management for a hybrid drive system for a vehicle recovers input and output performance of a battery if the battery temperature is low. If the battery temperature is less than or equal to a predetermined value (or if the battery internal resistance is greater than or equal to a predetermined value), the battery needs to recover its input and output performance. Under this condition, the state of charge (SOC) of the battery is determined and compared with a predetermined value. The comparison result is used to determine whether the battery is capable of discharging or the battery needs charging. If SOC is greater than or equal to the predetermined value, a controller conducts forced discharge from the battery to operate an electric motor of the hybrid drive system in power mode. This forced discharge causes an increase ion the battery temperature, thus causing the battery to recover its input and output performance.
