<p>PROBLEM TO BE SOLVED: To accurately control a magnetic path gap by increasing the stiffness of a cylindrical member that controls magnetic flux, according to the rotation of a rotor in an apparatus for controlling magnetic flux, in a permanent magnet type generator/electric motor. SOLUTION: In the cylindrical member 7, magnetic permeation members 17 and a non-magnetic permeation member 18 that is arranged between the magnetic permeation member 17 are alternately laminated cylindrically. A width t2 in the peripheral direction of the magnetic permeation member 17 is smaller than a width t1 of a slot 22 between comb sections 20 of a stator 4. A chamfered section 25 is formed at both the corner sections of the outer periphery side in the radial direction of a second quadrilateral in the magnetic permeation members 17, and a chamber section 24 is formed at both the corner sections of the comb section 20 of the station 4. A predetermined amount of clearances t3 and t4 are formed between both the corner sections at the inner- periphery side in the radial direction of the comb section 20 by the chamber sections 24 and 25, at a position where the permeation members 17 correspond to the slot 22, thus composing the magnetic path gap.</p> |
