Rotating electrical machine |
摘要 |
Provided is a rotating electrical machine including an armature core on which an armature winding is wound; a rotor core which is supported by a rotation axis at a predetermined air gap in an inner diameter side of the armature core, and includes claw-shaped magnetic pole portions in which adjacent magnetic poles have different poles and a cylindrical portion having a field winding; and a permanent magnet which is provided in a magnetic circuit of the rotor core and supplies magnetic flux to the armature core with the field winding, wherein a magnetic short-circuiting mechanism for demagnetizing the magnetic flux of the permanent magnet by deforming a portion of the magnetic short-circuiting mechanism by a centrifugal force and short-circuiting between the magnetic pole portions of the rotor core is provided in the rotor core.
