To design and verify the performance of motor controller, a hardware-in-the-loop （HIL） platform is presented for permanent magnet synchronous machine. The proposed permanent magnet synchronous machine model is a phase domain model with inductance and flux profiles computed from the JMAG finite element analysis soft- ware. The permanent magnet synchronous machine and three-phase IGBT inverter model are implemented on RT- LAB which can be connected to a real DSP controller. The RT-LAB real-time simulation model runs at a 20 Ixs rate and the results of HIL platform are compared with those of real objects. The difference of the fundamental current amplitude is within 5% , which proves the effectiveness and accuracy of the HIL platform. By connecting the RT- LAB real-time simulator to an external controller, this HIL platform allows high fidelity HIL simulation of motor drives and enables the design engineers to test the system and the controller with an accurate, finite element based motor model running in real-time.
