Method for characterizing stator of rotating-field machine, involves interrupting electrical connection between one side of first input terminal of stator and another side of input potentials of inverter

摘要

The method involves interrupting (61) an electrical connection between one side of a first input terminal of the stator and another side of input potentials of an inverter. An input direct voltage is applied between the first input terminal and input potentials. A second input terminal of input terminals is provided (63) to a second output potential of the inverter. The first measured voltage is compared (69) with a first expected voltage. Independent claims are included for the following: (1) a device for characterizing a stator of a rotating-field machine; and (2) a computer program product.
