CONTROL DEVICE FOR AN ASYNCHRONOUS ELECTRIC MACHINE, ELECTRIC PROPULSION SYSTEM- COMPRISING SAID DEVICE, AND METHOD FOR CONTROLLING AN ASYNCHRONOUS ELECTRIC MACHINE

摘要

A control device for an asynchronous electric machine (2) comprises a first computing unit (10) configured for defining a first signal (Sl), which is correlated to an operating voltage (V) to be applied to the electric machine (2). The first signal (Sl) is defined as a function of a second signal (S2) indicating a desired stator frequency (f1d) of the operating voltage (V), and as a function of a third signal (S3) indicating a desired slip frequency (fsd) of the electric machine (2).
