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 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 stator for a rotary electric machine is provided to curb decreases in output caused by magnetic flux leakage. The stator has a stator core with stator coils that are wound around tooth parts of the stator core. The tooth parts of the stator core are arranged to form a rotational space with respect to a rotor, and housed inside the slots and cooling medium passages are formed inside the slots by blocking the openings of the slots. The protrusions are provided that protrude into the slots from both lateral surfaces of the tips of the tooth parts. The plates formed with grooves on both sides thereof that fit on the tips of the protrusions are arranged between adjacent ones of the protrusions so as to block the openings of the slots. A sealing member is formed on the rotor side of the plates.

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： 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.
