Patent number: 9325218Abstract: A laminated rotor and an electric machine including the laminated rotor are disclosed. In an embodiment, a rotor comprises a plurality of stacked laminations, wherein each lamination includes a plurality of radially extending slots arranged about a circumference of each of the plurality of laminations, and the plurality of radially extending slots in successive laminations in the stack are aligned. A stud member passes longitudinally through at least one hole in the lamination stack, and a plurality of coils are positioned within the plurality of slots. Fewer than all of the plurality of slots have a coil positioned therein, leaving at least three slots empty. Balance members may be placed in the slots that do not have a coil positioned therein to balance the rotor.Type: GrantFiled: July 6, 2011Date of Patent: April 26, 2016Assignee: General Electric CompanyInventors: Dmitry Yurevich Semenov, Anthony Salvatore Arrao, Mikhail Avramovich Avanesov, Richard Nils Dawson, Evgeny Victorovich Kazmin, Timothy Gerald Schmehl, Yury Danilovich Vinitsky

Publication number: 20150097371Abstract: An electromagnetic braking system includes an electrically conductive disc coupled to a rotatable shaft of a power generation system. The rotatable shaft is operatively coupled to a prime mover and a generator. The electromagnetic braking system further includes an inducting unit for applying an electromagnetic braking torque on the electrically conductive disc when commanded by a control signal and a controller for receiving an activation signal from an activating unit, receiving a rotational signal from a rotational sensor coupled to the rotatable shaft or the generator, determining a control signal when the rotational signal is outside of a threshold, and, when the activation signal is active and the rotational signal is outside of the threshold, sending the control signal to the inducting unit to regulate a rotational dynamic of the rotatable shaft.Type: ApplicationFiled: December 10, 2014Publication date: April 9, 2015Inventors: Ara Panosyan, Christoph Boeld, Herbert Schaumberger, Stefan Schroeder, Lukas Vogl, Mikhail Avramovich Avanesov
