The self-commissioning method for PMSMs at standstill is presented in this chapter, which requires no additional hardware but only a VSI. Considering detailed identification error analysis of inverter nonlinearity influence at different rotor positions, the inductance parameter identification method is introduced in detail. After estimating the initial rotor position, the inductances are identified by injecting high frequency signal in the estimated d- and q-axes, respectively. The proposed inductance identification belongs to the frequency-domain approach. Additionally, a supplementary DC current is injected into the d-axis to attenuate the influence of the inverter nonlinearities and keep the rotor at the initial position.
