Presented in this paper is an advanced Finite-Element-Analysis (FEA) based PMSM motor drive emulator implemented on FPGA. FEA simulation of PMSM improves the accuracy with regards to classix Park DQ model by enabling the inclusion of saturation and non-sinusoidal back-EMF into the simulation. Implementation on an FPGA minimizes the model latency during closed-loop testing with an ECU. The drive model is an improved version of previous simulator implementation in many aspects: first, a nodal solver is used for the simulation of the inverter, thus enabling all type of fault inclusion like IGBT open/short circuit, motor terminal short circuit or even diode malfunction in the IGBT/Diode pairs. Secondly, the DC-link model is extended to include its inductance. Finally, the FEA-computed torque is now computed inside the FPGA
