A system and methods are provided for a telemetry system for monitoring magnet temperatures within an operating electric motor. The telemetry system includes one or more sensors that are coupled with magnets comprising a rotor of the electric motor. A telemetry controller is mounted near a motor shaft comprising the rotor and wired to the sensors. The telemetry controller receives measured data signals from the sensors and transmits temperature-related information during operation of the electric motor. The telemetry controller is powered by way of an electric current induced in a winding coupled with a portion of the rotor that exposes the winding to a varying magnetic flux. The winding may comprise two or more smaller windings disposed at different locations of the rotor. A telemetry receiver is disposed in a stationary configuration nearby the electric motor such that wirelessly transmitted temperature-related information is received from the telemetry controller during operation of the electric motor.

An actuator device includes a support part, a first movable part, and a second movable part. The second movable part includes a pair of first connection portions positioned on both sides of the first movable part on a first axis and connected to a pair of first connecting parts, and a pair of second connection portions positioned on both sides of the first movable part on a second axis and connected to a pair of second connecting parts. An outer edge of each of the pair of the first connection portions includes a first linear portion that extends along a second axis direction. An outer edge of each of the pair of the second connection portions includes a second linear portion that extends along a first axis direction.

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.
