摘要： A rotating electric machine includes a rotor and a stator. The rotor has n permanent magnets arranged in a circumferential direction. The stator includes m slots and teeth arranged in a circumferential direction and r-phase coils wound around the teeth. The coil has, in each phase, s phase coils connected in series from a first phase coil to an sth phase coil. The ratio of the number of poles n of the permanent magnets to the number of slots m is given as n : m = (3±1) : r. The first phase coils of respective phases are connected to an inverter, and the sth phase coils of respective phases are connected to a neutral point. The phase coils are wound around the teeth such that the first phase coils are not adjacent to each other in a circumferential direction.

摘要： The present invention provides a rotary electric machine that can achieve prompt restarting and that can also reduce eddy current loss by reducing eddy currents that flow through an outer circumferential surface of a boss portion of a pole core due to the changes in flux in field magnetic flux build-up during starting to enable prompt field magnetic flux build-up in response to a restarting command. In a rotary electric machine according to the present invention, a first pole core body (17) and a second pole core body (21) are produced using solid cores, and first slits (25) are formed on outer circumferential surfaces of a first boss portion (18) and a second boss portion (22) at a uniform pitch in a circumferential direction so as to have groove directions oriented in an axial direction to disrupt pathways of eddy currents that flow on the outer circumferential surfaces of the first boss portion (18) and the second boss portion (22).

摘要： The present invention provides a dynamoelectric machine enables permanent magnet holding reliability to be increased, induced voltage during no-load de-energization to be suppressed, and thermal demagnetization of magnets due to high-frequency magnetic fields that are induced by stator slots to be avoided.
In a dynamoelectric machine according to the present invention, first and second permanent magnets are held by means of first and second magnet seats on first and second yoke portions so as to face inner circumferential surfaces of tip end portions of first and second claw-shaped magnetic pole portions. The first and second permanent magnets are magnetically oriented in a reverse direction to orientation of a magnetic field that the field coil produces.

摘要： Provided is a Lundell type rotating machine with high efficiency and high output, which has a rigid and magnetically advantageous magnet retention structure. A rotor iron core includes laminated magnetic-pole members mechanically and magnetically coupled to two laminated magnetic end plates, which extend in an axial direction so as to be brought into meshing engagement with each other to constitute a Lundell type rotor iron core, and permanent magnets provided between the magnetic-pole members. The magnetic-pole members are retained in predetermined positions between the magnetic end plates by dovetail grooves of a non-magnetic retention body over substantially the entire lengths. The permanent magnets are held in direct contact with the magnetic-pole members so as to be interposed therebetween. Thus, the magnet retention structure which is mechanically rigid and magnetically highly efficient even when increased in size can be obtained.

摘要： Magnet insertion holes 7a to 7c for embedding a plurality of permanent magnets per pole are formed in a rotor core 6 in a protruding shape toward a center of a rotor. A pair of flux control holes 20a and 20b formed in a symmetrical shape with respect to a center line between magnetic poles is provided for each magnetic pole in a magnetic pole gap 22 of the rotor core 6. Where d is a diameter of the respective flux control holes 20a and 20b, m is a center-to-center distance thereof, b is a width of the magnetic pole gap 22, and τ is a pole pitch between magnetic poles, the flux control holes 20a and 20b are provided so that a value of m/τ obtained by standardizing the center-to-center distance m by the pole pitch τ satisfies 0.08
