To　improve　the　test　efficiency　and　reduce　the　test　cost,　this　paper　presents　a　design　method　of　universal　powerhardware-in-the-loop　(PHIL)　simulator　for　brushless　DC　motor　(BLDCM)　and　permanent　magnet　synchronous　motor　(PMSM).　The　actual　stator　winding　is　simulated　by　the　power-level　current　source　in　the　simulator,　thus,　the　electric　power　can　be　interacted　between　the　simulator　and　the　motor　driver.　By　the　method　of　bilinear　transform　and　inverse　Z-transform,　the　line　voltage　based　numerical　models　of　the　virtual　motors　are　derived.　Moreover,　the　relationship　between　the　line　voltage　and　phase　current　of　the　virtual　motors　is　analyzed,　which　is　used　to　calculate　the　phase　current　commands　in　the　numerical　models.　Furthermore,　the　universal　PHIL　simulator　is　implemented　and　the　real-time　simulation　is　performed,　and　then　the　offline　simulation　with　MATLAB　software　and　the　actual　motor　test　are　also　performed　to　verify　the　simulator　results.　The　simulation　and　experimental　results　show　that　both　PMSM　and　BLDCM　can　be　simulated　accurately　at　the　power　level　without　changing　any　hardware　of　the　motor　driver　and　the　simulator.
