Method and device for the detection of short circuits in the stator laminated core of electric machines.

摘要

Described are a device and a method for detecting turns in the laminated core (5) of a stator (1) of an electric machine or a generator. In this case, by means of an auxiliary coil and an auxiliary current of the stator (1) is magnetized for the measurement and with a receiving device (S1, S2), the magnetic field (7, B) measured. The receiving device has at least two detectors (S1, S2) which are arranged at two different radial positions with respect to the rotor axis (3), simultaneously measuring the magnetic field (7, B) at these two different radial positions with respect to the rotor axis (3) The two signals measured at these different locations are evaluated in size and / or in particular in phase relationship for the detection of turns and compared with each other.
