Abstract :
This paper examines winding faults in a demonstrator switched reluctance motor (SRM) drive, based on the specification for an aircraft fuel pump. This motor drive has been designed with a degree of inherent fault tolerance and is capable of continued operation in the presence of a variety of faults. The paper focuses on the possible consequences of winding insulation failure within a phase of the machine. A method of detecting turn to turn short circuits which may result from winding insulation breakdown is presented, along with a strategy for continued post fault operation of the drive
