CM high-frequency model of the motor has been identified. In
particular, the motor has been modeled using the circuit topology
shown in Fig. 3, whose parameters have been identified
by using the frequency response of the motor CM impedance.
The impedance has been measured between the three phases
terminals of the motor connected together and the ground connection,
up to 1MHz, using theRohde&Schwarz vector network
analyzer ZVER. The R,L,C1 , and C2 (where C1 = C2 = C)
circuit parameters have been identified using a fitting function
embedded in MATLAB [32], [33]. The obtained HF parameters
of the motor circuit model are reported in Table III. Fig. 4
shows the matching between estimated and measured frequency
responses of the motor impedance
