Abstract: A generator housed in a wind turbine nacelle includes a generator rotor that is mounted to gearbox output pinions, thereby eliminating the need for couplings. The generator frame is located directly on the gearbox and is located to control the air gap. To facilitate removal of the generator, tapers are used that have steep angles that exceed the friction coefficient of the materials used. To provide adequate support over its length, the shaft employs dual tapers, each short and precisely located conical surface of which provides exact location on the near and far sides of the shaft. The length of straight shaft between the dual locating tapers serves to support the generator during mounting and de-mounting. During installation, the tapers center the rotor and bullet pins center the frame (stator). When the system aligns the rotor and stator, retainer elements act as labyrinth seals designed to protect the generator interior from contamination.

Abstract: An apparatus for converting between mechanical and electrical energy, particularly suited for use as a compact high power alternator for automotive use and “remove and replace” retrofitting of existing vehicles. The apparatus comprises a rotor with permanent magnets, a stator with a winding, and a cooling system. Mechanisms to prevent the rotor magnets from clashing with the stator by minimizing rotor displacement, and absorbing unacceptable rotor displacement are disclosed. The cooling system directs coolant flow into thermal contact with at least one of the winding and magnets, and includes at least one passageway through the stator core. Various open and closed cooling systems are described. Cooling is facilitated by, for example, loosely wrapping the winding end turns, use of an asynchronous airflow source, and/or directing coolant through conduits extending through the stator into thermal contact with the windings.

Abstract: Cooling oil passes through a cooling oil passage (28) on the inside of an iron core (7), and cools the inside of the iron core (7). Further, cooling air passes through a cooling air passage (31) in the inside of the iron core (7) and a clearance (5) between the internal periphery of the iron core (7) and the external periphery of a rotor (4), and cools the inside of the iron core (7) and the rotor (4). Therefore, it is possible to effectively cool the internal periphery side of a stator (6) and the rotor (4). When a cooling oil is sprayed from the cooling oil passage (28) into the cooling air passage (31), it is possible to obtain a more effective cooling effect by utilizing the latent heat of vaporization of the mist of the cooling oil.
