Abstract: An electrical power generator for a wind turbine comprising: a generator housing, a stator at a radially outward position and a rotor in a radially inward position, wherein the rotor comprises a cylindrical ring structure arranged about a rotational axis, R, and defining a central hollow portion. The electrical power generator further comprises a rotor shroud attached to the generator housing and which extends about the rotational axis, R, wherein the rotor shroud includes a dome portion that extends into the central hollow portion of the rotor so as to protect the cylindrical ring structure of the rotor. Advantageously, the rotor shroud provides a tunnel-like surface that extends into the central hollow portion of the generator so as to prevent objects such as tools from contacting components of the rotor. The invention also relates to a method for 15 assembling such an electrical power generator with a rotor shroud.

Abstract: A generator rotor assembly (42) comprises a cylindrical ring structure (46) defining a central hollow portion and arranged to rotate around a rotational axis. The cylindrical ring structure (46) comprises a plurality of permanent magnet packages (48) arranged coaxially around the rotational axis, the permanent magnet packages (48) comprising a plurality of coaxially stacked ring-shaped segmented layers (80), a plurality of tie rod holes (86) and a plurality of tie rods (54). The coaxially stacked ring-shaped segmented layers (80) comprise a plurality of contiguous segment sheets (82) arranged around the rotational axis to form the ring-shaped layer, the stacked layers (80) being staggered such that segment breaks between two contiguous segment sheets (82) in one of the layers are angularly offset with respect to segment breaks between two contiguous segment sheets (82) in an adjacent layer. The tie rod holes (86) extend axially through the layers of the permanent magnet packages (48), wherein the plurality of tie rod holes (86) of adjacent permanent magnet packages (48) are complementary in size and position, such that a plurality of tie rod bores is defined. The tie rods (54) extend through respective ones of the plurality of tie rod bores.

Abstract: Apparatus comprising a first shaft and a second shaft supported in a substantially concentric relationship so that they are able to rotate relative to one another about a rotational axis (R); wherein one of the first and second shafts passes through a bore defined in the other of the first and second shafts; a seal arrangement between the first and second shafts, said seal arrangement being locked from rotational movement relative to said first shaft; wherein the seal arrangement comprises a first portion that is rotatably mounted on the second shaft by a bearing and a second portion that is configured to seal against a miming surface defined by the second shaft. Advantageously, since the seal arrangement is rotatably mounted on the same shaft against which it forms a seal, the sealing arrangement accommodates for alignment errors between the first and second shafts.
