Stator Design and Performance of Superconducting Motors for Aerospace Electric Propulsion Systems

Assessment of Uncertainty in Aerospace Propulsion System Design and Simulation

The subject of uncertainty analysis in complex systems design is a broad and bourgeoning field of study. This paper focuses on only three very specific areas of current propulsion research wherein uncertainty plays a pivotal role in the problem formulation. The first is probabilistic approaches to matching engine cycle models to test data. Engine cycle models must have a high confidence of repr...

A Design Package for Single Tooth per Stator Pole Switched Reluctance Motors

A design package is developed for a single-tooth per stator pole switched reluctance motor, 6/4. The rather simple assumed flux path method is used to estimate the unaligned permeance including the leakage permeances and the effects of shallow slot and tooth taper. The possibility of making rotor tooth width greater than stator tooth width is examined using the developed package. The result app...

Design of an Active Approach for Detection, Estimation and Short-Circuit Stator Fault Tolerant Control in Induction Motors

Three phase induction motors have many applications in industries. Consequently, detecting and estimating the fault and compensate it in a way that the faulty induction motor satisfies the predefined goals are important issues. One of the most common faults in induction motors is the short circuit of the stator winding. In this paper, an active fault-tolerant control system is designed and pres...
