摘要：A rotating electrical machine is provided in which, even when torque from awater 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 rotatingshaft, spider arms extending radially from the vertical rotating shaft, and a rotor corecomponent provided to the outer circumference of the spider arms. A T key and cottersare inserted into and secured to a key way provided to an abutment surface of the innercircumference of the rotor core component and the top end of the spider arm. A platespring is mounted to a surface of the spider arm, the surface facing a rotational directionfor electrical generation. The plate spring has one side engaging the spider arm, theother side engaging the rotor core component, and a middle portion bolted from anopposite surface of the spider arm.
