<p>PROBLEM TO BE SOLVED: To provide a magnet field system rotating type dynamo-electric machine, capable of controlling an output in wide range by controlling the field system efficiently by means of controlling magnetic flux generated with a controlling coil provided at the side of a stator. SOLUTION: A control coil Wc is provided at the side of the stator 2, and a field system control yoke 10 is provided, that has an axial direction magnetic path forming part 10A and a radial direction magnetic path forming part 10B. On the inner circumference of the rotor yoke 101, main rotary magnetic poles P5 made of a permanent magnet and interpoles Q1 made of a ferromagnetic material are provided alternately. The main rotary magnetic poles P5 are provided, in such a way as to face the magnetic pole surfaces, only at the ends of the protruding parts A1, A11 of a stator core 201, while the interpoles Q1 are provided in such a way as to face both the magnetic pole surfaces at the ends of the protruding parts of the stator core and those on the outside circumference of the radial direction magnetic path forming part 10B are provided on the field system control yoke 10.</p> |
