Modular excitation system

摘要

An excitation device for high-energy tests of stator cores of electric generators or motors is disclosed. The excitation device includes one or more excitation modules. Each excitation module includes an excitation winding and a power supply configured to drive an excitation current through the excitation winding which contributes to the overall excitation of the stator core. The excitation module further includes a capacitor. The power supply of the excitation module acts as current source at its output.
