Abstract: A bearing assembly is provided with an improved mounting for a temperature sensor for monitoring a temperature of a race of the bearing. The assembly includes a temperature sensor assembly mounted to the race of the bearing and a thermal insulator arranged to thermally insulate the sensor from heat exchange with the surrounding environment and/or neighboring components to which the bearing or assembly is mounted, in order to improve accuracy, reliability and speed of response of the temperature sensor readings.

Abstract: A rotor for a dynamo electric machine comprises a rotor body 12 defining a plurality of poles in the form of limbs 16 around which windings 18 are provided, and a wedge arrangement 20 spanning the space 42 between adjacent limbs 16 and serving to secure the windings 18 in position, and a discharge passage 44 for delivering coolant to the said space.

Abstract: A disconnect mechanism is provided which, upon a suitable trigger event, such as excess temperature causes a camming element 40 having a tapered head 52 to move under the urging of a compression spring 60 such that the tapered head 52 becomes trapped between a rotating element 32 and a support 42. This gives rise to frictional inter-engagement which prevents further rotation of the rotating element 32 and thereby locks the rotating machine against further rotation. This in turn causes the shear region to fail thereby drivingly disconnecting the machine from its prime mover.
