FIELD: measurement technology.
SUBSTANCE: invention is related to measurement of air gap in an electrical machine, for example, in a hydraulic generator. Device for measurement of shaft runout and dynamic form of hydraulic generator rotor includes laser triangulating sensors with an indicating device arranged in the channel of a core pack and connected to a PC input. At that, the above sensors are fixed in one plane so that their beams are arranged at an angle of 90°.
EFFECT: faster measurement of shaft runout and dynamic form of hydraulic generator rotor, as well as possibility to make measurements in real time.
