    摘要: In a rotary electrical machine, a rotor has a field core, a field winding, and a cylindrical short-circuit member. The field core has a cylindrical boss part and a plurality of magnetic pole parts that are disposed on the outer peripheral side of the boss part and in which magnetic poles of different polarities are alternately formed in the circumferential direction. The field winding is wound on the outer peripheral side of the boss part. The short-circuit member is disposed on the outer peripheral sides of the magnetic pole parts and magnetically connects together the magnetic pole parts adjacent to each other in the circumferential direction. A surface of the short-circuit member opposed to the stator is formed in a concave-convex shape in which protrusion portions protruding along the radial direction and groove portions recessed along the radial direction are disposed alternately and continuously with each other.

    摘要: A rotating electric machine includes a stator and a rotor. The stator includes a stator core and an armature coil wound on the stator core. The rotor is arranged radially inside the stator to radially face the stator. The rotor includes: a field core having a plurality of magnetic pole portions for respectively forming a plurality of magnetic poles the polarities of which are alternately different in a circumferential direction; a field coil wound on the field core; and a tubular short-circuiting member that is arranged radially outside the magnetic pole portions to cover radially outer surfaces of the magnetic pole portions and magnetically connects each circumferentially-adjacent pair of the magnetic pole portions. The short-circuiting member is provided within an axial range between two axial ends of the stator core.

    摘要: Provided is a so-called Lundell-type generator capable of avoiding generation of eddy current in rotor iron-cores without complicated structure. The generator includes a stator, a rotary shaft, first and second rotor iron-cores, and a rotor coil. Each rotor iron-core includes a base and rotor magnetic-pole portions extending axially from the base, the rotor coil disposed on the inside thereof. Each rotor iron-core is formed of a plurality of unit plates stacked axially. The unit plates integrally include respective basal plate portions stacked to form the bases and a plurality of magnetic-pole plate portions stacked to form the rotor magnetic-pole plate portions stacked to form the rotor magnetic-pole portions.

    摘要: In a rotary electric machine, a first pole core body and a second pole core body are produced using solid cores, and first slits are formed on outer circumferential surfaces of a first boss portion and a second boss portion at a uniform pitch in a circumferential direction so as to have groove directions oriented in an axial direction to disrupt pathways of eddy currents that flow on the outer circumferential surfaces of the first boss portion and the second boss portion.

    摘要: A generator system comprises an inner generator rotor, an outer generator rotor, and a stator. The inner rotor is mounted on the first shaft rotating at a first speed, while the outer rotor is mounted on a second shaft coaxial with the first shaft, and rotating at a second speed different from the first speed. The outer rotor is mounted coaxially with and radially outward of the inner rotor, and the stator is mounted coaxially with and radially outward of the outer rotor.
