摘要： PROBLEM TO BE SOLVED: To provide a rotary electric machine in which a size reduction and a high performance are realized by improving a cooling method.
SOLUTION: In the rotary electric machine, assuring of a magnetic path by the deflection of a magnetic flux line 25 and enlarging of a region 26 which can be cooled are realized by forming a stator core 23 of a dust core material and adding a collar-like additional region 23a to this stator core 23. The reason why such a constitution is formed is because since a loss heat is generated in response to a magnetic flux in the stator core 23 and simultaneously the heat is added as the current loss of the stator coil 22 itself at the place where the magnetic flux in the stator core 23 is generated around a stator coil 22 from the stator to the magnet of a rotor, it is desired to set a refrigerant channel 26 in the region which surrounds the magnetic flux in the stator core 23. In other words, the stator core 23 is suitable to have the refrigerant channel 26 in the interior or the front surface of the stator core of the region which is not interfered with the dense part the magnetic flux line 25 generated with the stator coil 22, and passing through the interior of the stator core 23.

摘要： PROBLEM TO BE SOLVED: To provide an insulation film suitable for covering powder for a magnetic core and superior in heat resistance.
SOLUTION: This is an insulation coating in which indispensable constituting elements are a first element group composed of P and O, and a second element to produce positive ions of divalence or more in which an ion radius in 6 coordination number defined by Shannon is not less than 0.073 nm, and in which B is not substantially contained. Because the second element with a large ion radius is introduced as a mesh modifying structure into a mesh forming structure formed by the first element group, the heat resistance of the insulation coating can be improved.

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a composite member obtained by integral molding of powder.
SOLUTION: The method for manufacturing an integrally molded composite member comprises the steps of: filling a raw powder mainly containing a metallic powder with an internal lubricant controlled to 0.05 mass% or less with respect to 100 mass% of the total, in the periphery of a core material; and pressurizing the raw powder after the filling step, to mold a powder compact integrally combined with the core material in a tight-fit state. The present invention has been achieved based on a finding that when an annular powder compact is molded with a high pressure from the raw powder containing little amount of the internal lubricant, the minor diameter of the compact is reduced. By taking advantage of the phenomenon, the core material can be strongly combined with the powder compact through integral molding of the powder.

摘要： PROBLEM TO BE SOLVED: To provide an axial-type permanent-magnet motor capable of easily being set to suppress generation of cogging torque, while preventing decrease in the torque of the motor.
SOLUTION: In this axial-type permanent-magnet motor, contours 24a, 20a of a coil 24 and a permanent magnet 20 are in such a direction that the direction crosses a rotor rotational direction are set to be approximately a straight-line shape, and the contour 24a of the coil 24 and the contour 20a of the permanent magnet 20 are set so as to contact/separate from each other in a rotor rotating direction in an non-parallel condition, when the rotor rotates. Therefore, when a magnetic pole by the permanent magnet 20 passes through a magnetic pole by the stator coil 24 during the rotation of the rotor, fluctuations in the flux gradually change with the rotational speed of the rotator, so that rapid torque fluctuations are suppressed, and cogging torque is relieved.

摘要： PROBLEM TO BE SOLVED: To provide a structure which can reduce the number of permanent magnets while securing desired motor torque.
SOLUTION: An axial permanent magnet motor includes a rotor having a plurality of the permanent magnets disposed at predetermined intervals along the rotating direction of a rotary shaft so that poles are alternately disposed, and a magnetic element 24 disposed between the permanent magnets 20. Then, when a rotating magnetic field is generated in a stator disposed at a position opposed to the rotor, magnet torque is generated between teeth of the magnetized stator and the permanent magnet 20, and reluctance torque is generated between the teeth and the magnetic element 24. As a result, even if the number of the permanent magnet 20 is reduced and the magnet torque is reduced, it is compensated by the generation of the reluctance torque, and desired motor torque is secured.
