In this paper, a permanent magnet synchronous machine with fractional-slot and 5-phase winding is studied. By superposing of the back EMF (electro-motive force) phasors of all coil-sides in a phase winding, the winding factor of the machine is calculated. The idea of this calculation method is a clear, and operation is easy and fast. In normal working, one-phase open-circuit fault, opencircuit ...

Fault detection and its restoration is the major challenge for smooth functioning of Multi-Level Inverter (MLI). In this paper, fault clearance scheme an Open Circuit (OC) on a 3-level 5-level Cascaded H-Bridge (CHBMLI) has been developed tested to improve reliability suitability system. An accurate fast detection, isolation bypassing faulty bridges enhance reliability, suitability, acceptabili...

Abstract: Multi-phase motors are gaining more attention due to the advantages of good fault tolerance capability and high power density, etc. By applying dual-rotor technology to multi-phase machines, a five-phase dual-rotor permanent magnet synchronous motor (DRPMSM) is researched in this paper to further promote their torque density and fault tolerance capability. It has two rotors and two se...

Kariro Pb prospect area, which is located in northwest of Boshruyeh, occurs as vein-veinlets, open space filling, and cement of fault breccia in Middle Jurassic metamorphosed shale (slate) unit of Baghamshah Formation. Mineralization zones contain dolomite (70-85%) and galena (0.5-2.5%) with small amounts of pyrite, quartz, and calcite. Dolomitization and silicification of host rock are the mos...

In this paper, a fault diagnosis algorithm for brushless DC (BLDC) motor drives is proposed to maintain control performance under switch open-damage. The proposed fault diagnosis algorithm consists of a simple algorithm using measured phase current information and it detects open-circuit faults based on the operating characteristic of BLDC motors. The proposed algorithm quickly recovers control...
