Once the modeling of the asynchronous machine is completed, and the control of the asynchronous drive has been studied, namely pulse width modulation, the effectiveness of the adopted technique can only be confirmed after supplying the machine with the voltages delivered by the inverter, and this for two tests, no-load and load.
