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： The present invention provides a rotating electrical machine including a rotor core that does not produce narrow areas in rotor slots even if circumferential ends of fan-shaped segment cores are displaced radially outwardly and circumferentially during operation. In the present invention, slots near circumferential ends of the fan-shaped segment cores are made larger than slots in circumferential intermediate portions of the segment cores. With such a configuration, even if the circumferential ends of the segment cores are displaced radially outwardly and circumferentially during operation, the circumferential ends of the segment cores forming the large slots do not protrude into the slots formed in the circumferential intermediate portions of axially adjacent segment cores, thereby preventing narrow areas from being produced in the rotor slots.

摘要： A lead conductor penetrating portion that bring out lead conductors to the inner diameter side is formed in a winding holding portion of a clamp ring for holding a rotor winding that overhangs from a rotor core, and furthermore a stopper is formed in a lead portion on the inner diameter side of the lead conductor, and a centrifugal force-resistant member for holding a centrifugal force acting on the lead conductor is interposed between the stopper and the inner diameter side of the winding holding portion.
