Title:
回転電機
Document Type and Number:
Japanese Patent JP7144966
Kind Code:
B2
Abstract:
A rotating electrical machine of a brushless wound field type disposed between a stationary case and a rotating member that rotates inside the stationary case includes a stator held by the stationary case, the stator including an AC coil that generates a rotating magnetic field with an alternating current, a field core held by the stationary case, the field core including a field coil that generates a magnetic flux with a direct current, a rotor fixed in contact with an outer circumferential surface of the rotating member and held rotatably relative to the stator and the field coil, a rotor side core portion that is a part of the rotating member. The magnetic flux of the field coil passes from the field core through the rotor via the second air gap, the stator via the first air gap, the rotor via the first air gap, the rotor side core portion, and the field core via the third air gap.
