Abstract: The invention relates to a device for adjusting the angle of attack of a rotor blade of a wind power plant, comprising a flexible clad drive train that can be moved by a driving wheel, wherein the rotor blade can be rotated about the longitudinal axis thereof by said drive train in opposite directions. According to the invention, the clad drive train can be moved only in a single plane perpendicular to the rotational axis of the driving wheel and engages on a pivot bearing ring forming an end piece of the rotor blade, and the driving wheel is connected to a motor/transmission unit, which is mounted on the hub of the rotor blade, for the individual adjustment of the rotor blade.

Abstract: Disclosed is a mainframe for receiving a rotor-generator assembly of a gearless wind turbine, wherein the mainframe connects the rotor-generator assembly to the tower of the wind turbine; is rotatably mounted on the tower; and comprises pipe sections arranged at an angle to each other, one of which can be connected to the rotor-generator assembly and the other of which can be connected to the tower. The pipe section that can be connected to the rotor-generator assembly is connected to the lateral surface of the other pipe section by way of an end edge surface facing away from the rotor-generator assembly, and the lateral surface of the other pipe section extends into the region surrounded by the connection.

Abstract: A generator for a wind power has teeth which are surrounded by windings and separated by slots, and permanent magnets that form the poles of the exciter field. The ratio of the number of slots to the product of the numbers of poles and winding phases is fractional and >1. Alternatively or additionally, the front and/or rear edges of successive poles or groups of poles are oppositely inclined to the axis of rotation.

Abstract: A method for mounting permanent magnets that form magnetic poles on a permanent magnet support surface of the rotor of an electric machine includes the steps of forming a mold by the placement of a mold part against the support surface in such a way that the mold cavity of the mold is bounded on one side by the support surface inserting a permanent magnet into the mold so that the inserted permanent magnet is held in the mold in a desired position with respect to the support surface, and filling the mold with a thermosetting adhesive in such that the adhesive bonds the permanent magnet with the support surface and completely fills any spaces formed between the permanent magnet and the wall of the mold cavity.
