Abstract
The present disclosure relates to a measuring device for measuring vibrations of a rotor and to a method for measuring the vibrations of a rotor. Disclosed is a measuring device for measuring vibrations of a rotor of an electric machine having a guiding rod with a plate at one end of the guiding rod, the plate to abut at the rotor in operation, an actuator for inducing a shock to the rotor via the guiding rod and via the plate, and a monitor device for measuring the vibrations at the rotor caused by the induced shock.
Claims8
A measuring device for measuring vibrations of a rotor of an electric machine comprising
- a guiding rod with a plate at one end of the guiding rod, the plate configured to abut at the rotor in operation of the measuring device,
- an actuator for inducing a shock to the rotor via the guiding rod and via the plate,
- the actuator comprising a piston movable along the guiding rod,
- a locking system that exerts a retaining force on the piston, wherein when a centrifugal force exerted on the piston from rotation of the rotor exceeds the retaining force, the piston moves along the guiding rod and impacts the plate, and
- a monitor device disposed relative to the rotor to measure vibrations at the rotor caused by induced shock from the piston impacting the plate.
