Abstract	We performed circulating modeling before the studying inter turn fault. It used a finite element method (FEM)-based model to consider the magnetic non-linearity. By integrating the developed model with a current-controlled voltage source inverter (CCVSI) model, the distributed characteristics of an inter-turn fault operated by six-switched inverter are investigated considering the speed control. Also, this paper presents flux density distribution and torque characteristic to analyze the inter turn fault of interior permanent magnet (IPM) type BLDC motor having inter-turn fault. Also, we proposed new fault impedance modeling for magnetic characteristics analysis. The fault impedance is required to calculate the circulating current that causes magnetic distortion. Thus, this paper proposes a method for estimation of the circulating current taking into account the voltage at the shorted turn and the rotating speed. The analysis data were verified experimentally.
