    摘要： A flywheel energy storage system includes a rotating assembly having a plurality of magnets and a longitudinal axis about which the rotating assembly rotates and static assembly having a stator configured to magnetically interact with the plurality of magnets of the rotating assembly. The rotating assembly includes a rotor back iron supporting the plurality of magnets and disposed further from the longitudinal axis in a radial direction than the plurality of magnets. The back iron being formed of a material having a first stiffness, relative permeability of at least 10, and an electrical conductivity 10% or less than the electrical conductivity of magnetic steel. There is composite structure supporting the rotor back iron and disposed further from the longitudinal axis in a radial direction than the rotor back iron. The composite structure comprises a composite material having a second stiffness, which is greater than the first stiffness.

    摘要： A rotating electrical machine is provided in which, even when torque from a water turbine is reduced and reverse torque is applied due to load cut off, a rotor core is not eccentric to spider arms. The rotor of a rotating machine includes a vertical rotating shaft, spider arms extending radially from the vertical rotating shaft, and a rotor core component provided to the outer circumference of the spider arms. A T key and cotters are inserted into and secured to a key way provided to an abutment surface of the inner circumference of the rotor core component and the top end of the spider arm. A plate spring is mounted to a surface of the spider arm, the surface facing a rotational direction for electrical generation. The plate spring has one side engaging the spider arm, the other side engaging the rotor core component, and a middle portion bolted from an opposite surface of the spider arm.

    摘要： A generator comprises as a first part a stack of disc-like annular rotors spaced one from the other and coaxially located upon and rotating with an elongate central member each rotor having an inner annular portion and an outer annular portion, the outer annular portion bearing and/or comprising a magnetic annulus, one or more spacers being coaxially mounted around the central member in between the inner annular portions of each rotor and abutting against them in such manner such as to brace them to remain orthogonal to the longitudinal axis of the assembly as well as providing the required spacing therebetween, and as a second part, a stack of annular stators interposed between the rotors and mounted over the spacers but having an inner clearance diameter greater than that of the outer diameter of the portion of spacer over which they are located.
