摘要： The present invention provides a dynamoelectric machine that can reduce 12f vibrational force and suppress generation of irritating electromagnetic noise in a vicinity of 2,000 Hz in an idling state. In the present invention, an armature winding includes first and second three-phase windings, the first three-phase winding is configured by delta-connecting respective phase windings, and the second three-phase winding is configured so as to be Y-connected to the first three-phase winding by connecting respective phase windings in series to respective output ends of the first three-phase winding. The first and second three-phase windings are each installed in the stator core such that respective phase currents have a phase difference from each other. In addition, central angles of adjacent slot opening portions of the stator have a nonuniform pitch, and a turn ratio between the first three-phase winding and the second three-phase winding is within a range of 1.25 to 2.25.

摘要： The main motor for a railway vehicle is rotationally driven upon receiving an AC power supplied from an inverter circuit that includes a switching element formed by using a wide bandgap semiconductor. The inverter circuit applies a voltage having a PWM waveform to the main motor for a railway vehicle in at least part of a speed range of an electric vehicle. The stator of the main motor for a railway vehicle is configured to include an annular stator core provided with a plurality of slots in a circumferential direction and coils that are wound on the stator core and are accommodated in the slots, and includes a stator winding that is three-phase star-connected and is composed of parallel circuits the number of which is the same as the number of poles for each phase.

摘要： The present invention has been made for the purpose of obtaining a permanent magnet type dynamo electric machine, and a permanent magnet type synchronous generator for wind power generation, each of which is capable of reducing an eddy current loss of a rotor while having a construction of an integral one-piece rotor yoke. Each of the generators is constructed in such a way that it includes a rotor 100 having a plurality of magnetic poles composed of permanent magnets 4, and a stator 101 having armature windings concentratedly wound around teeth, and when the number of pole pairs of the magnetic poles of the rotor 100 is P, a diameter of the rotor 100 is DÄmÜ, and a spatial harmonic order of a predetermined harmonic component of an armature magnetomotive force of the rotor 100 is N (a mechanical angle 360 degrees is decided as 1-st order), the P, D and N meet a relationship of ((N + P) to the 1.5-th power) x (N to the minus 4-th power) x (the square of P) x D
