Abstract:
The aim of the invention is to improve the precision of measuring leakage field sensitive sensors on electric machines. According to the invention, the electric machine comprises a sensor device (4) which is sensitive to magnetic leakage fields mounted on one of the two active parts (1) or in a defined relative position in relation to the active parts. A magnetic screening device is arranged between the sensor device (4) and one of the two active parts (1). Also, the magnetic leakage fields no longer have an influence on the sensor device such that measuring precision is increased.
