A generator () for a wind turbine () comprises a rotor () with an axis of rotation, a stator and a radial and/or axial locking mechanism. The radial locking mechanism comprises a plurality of radial locks () with a fixed portion () coupled to the stator and a movable elongate portion () configured to move relative to the fixed portion () and radially with respect to the axis of the rotation to lock the stator in a radial direction. The rotor () may comprise at least one lock engagement feature () arranged at its end surface and an end shield () located axially outward and at least partially adjacent the end surface. The end shield () comprises at least one opening enabling access to the end surface of the rotor (). The axial locking mechanism may comprise at least one axial lock () comprising a removable block () configured to partly cover the at least one opening of the end shield () and a rotor engagement tool () for engaging the removable block () with the at least one lock engagement feature ().

Locking mechanism for a wind turbine generator

Embodiments herein provide an electrical machine comprising a stator with a stator winding arrangement, a rotor arranged for rotation inside the stator, a machine housing for housing the stator, at least one temperature sensor arrangement and wherein a sensor-end of the temperature sensor is arranged for insertion into the immersion sleeve and for insertion through an insertion bore arranged in an opening in the machine housing, so that the sensor-end of the temperature sensor is positioned within a cooling slot of the stator windings, when inserted, so as to allow sensing of a temperature of measure of temperature of the stator windings by electric connection to the wire-end of the temperature sensor.

External temperature sensor assembly

The invention relates to a generator for a wind turbine including a housing of substantially cuboidal form within which is mounted a stator. The stator has one or more multi-phase windings and a bus ring is provided for conveying electrical power from the windings to power take-off modules. One end of the power take-off modules is connected to the bus ring, and the other end of the modules has a plurality of power take-off interfaces for connection to power take-off cables. The distal ends of the power take-off modules are located in the corners of the cuboidal generator housing.
