Stator inter-turn fault detection of BLDC motor using third harmonic according to asymmetric magnetic fields

For precise operation of various applications such as vehicles, factory automation, robotics and aerospace, the need of motors are widely used. In particular, Brushless direct-current (BLDC) motors are currently preferred because of advantages which is miniaturization, high torque density and high efficiency in comparison to dc motors and induction motors. These motors should be considered for high stability and high reliability on faults which can seriously threaten the safety of operation.
