Abstract: A control device for an asynchronous electric machine comprises a first computing unit configured for defining a first signal, which is correlated to an operating voltage to be applied to the electric machine. The first signal is defined as a function of a second signal indicating a desired stator frequency of the operating voltage, and as a function of a third signal indicating a desired slip frequency of the electric machine.

Abstract: A control device for an asynchronous electric machine comprising a first computing unit configured for defining a first signal, indicating a desired slip frequency of the electric machine, as a function of a second signal correlated to a reference input velocity supplied through a user interface, and of a third signal correlated to a detected rotor angular velocity, the control device preferably comprising a user interface for supplying the second signal and a velocity-detection module coupled to the electric machine for supplying the third signal.
