The induction machine (IM) is commonly adopted in the industry, which plays an important role in energy conversion between mechanical and electrical power. This article proposes a power electronic converter based IM power hardware-in-the-loop (PHIL) emulator, which can emulate an IM with internal faults. The risk, time, and cost associated with generating real faults can be reduced, helping to overcome safety issues with actual faulted machines. The technique could also be applied in fault detection, diagnosis, and fault control areas. First, the IM mathematical model with an interturn short circuit of the stator winding is established. Based on that, the PHIL emulator is developed and tested for different interturn short-circuit conditions of an IM. A comparison of the emulator results with simulation results and actual IM results demonstrates the validity of the proposed solution.
