Abstract: The disclosure relates to a generator segment of a segmented generator, in particular of a permanently excited segmented rotary generator, of a wind turbine, comprising a rotor segment of a rotor, and a stator segment of a stator, wherein the rotor segment and the stator segment in an operation position are disposed so as to be mutually spaced apart in a radial direction by an air gap, and are disposed so as to be mutually spaced apart in an axial direction by an axial spacing; wherein the rotor segment and the stator segment are able to be disposed and/or displaced relative to one another along a rotation axis by the axial spacing, between an operation position and a transport position that is different from the operation position.

Abstract: A stator segment of a stator of a generator for a wind turbine has at least one stator laminated core which has at least two stator lamination stacks, wherein adjacent stator lamination stacks of the at least two stator lamination stacks are in each case spaced parallel to one another in an axial direction and forming in each case one stator cooling duct with a stator cooling duct width through which a cooling medium can be guided, in particular in a radial direction. A rotor segment of a rotor for a wind turbine has two or a plurality of magnet units are disposed spaced apart from one another in an axial direction, wherein the magnet units disposed adjacently in the axial direction define a circumferential gap with a gap width for feeding and distributing a cooling medium.

Abstract: A rotor segment of a segmented generator, in particular of a permanently excited segmented rotary generator, of a wind turbine, comprises a magnet carrier segment with a rotor circumferential face, in particular a rotor external circumferential face, which in a circumferential direction extends between a first and second separation interface by way of a segment length; the rotor circumferential face having a first separation interface portion having a first length proceeding from the first separation interface in the circumferential direction toward the second separation interface; and a second separation interface portion having a second length proceeding from the second separation interface in the circumferential direction toward the first separation interface; and a connection portion having a third length extending between the first and second separation interface; wherein in each case a reinforcement device for reinforcing the magnet carrier segment is disposed on the rotor circumferential face in the re

Abstract: A stator laminated core for receiving at least one coil unit of a stator segment of a stator of a generator, in particular a segmented stator of a segmented generator, for a wind turbine, comprises at least one stator lamination stack with two or more lamination stack units which are disposed spaced apart from one another in a circumferential direction and have a plurality of first stator lamination elements which are disposed next to one another, in particular stacked, in an axial direction; wherein the at least one stator lamination stack comprises at least one second stator lamination element, preferably two second stator lamination elements, which is different from the first stator lamination element and in each case connects adjacent lamination stack units of the two or more lamination stack units to one another.

Abstract: Provided is a method for heating a generator of a wind power installation during or before starting the installation. The generator is a permanent magnet synchronous generator configured to generate a stator current comprising at least one three-phase current. The installation is configured as a gearless installation and is connected to an electrical supply network for feeding electrical power into the network. The installation comprises a converter, connected to the generator, to control the generator to feed electrical power into the network. The method comprises rotating the rotor with a low rotational speed below a first limit and operating the converter such that the generator generates the stator current and electrical power, and no electrical power is fed into the electrical supply network. At least one portion of the stator current substantially circulates through the generator and the converter to consume power in generator windings to heat the generator.

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.
