Interturn short-circuit fault diagnosis in PMSM with partitioned stator windings
(Institution of Engineering and Technology, 2020-12)
A new signal-based strategy for stator winding interturn short-circuit fault detection and isolation in permanent magnet synchronous machines (PMSM) is proposed. The strategy is based on an analysis of the midpoint voltage ...
Analysis of the partial discharge pulse propagation in the stator winding of a synchronous machine
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2015-09-01)
In this paper, a study of the propagation of partial discharge pulses in the stator winding of a synchronous machine is presented. This study was performed by injecting artificial partial discharge pulses in the stator ...
Three-Phase Squirrel-Cage Induction Motor Dynamic Thermal Mathematical Model
(1996-01-01)
An electrical and thermal mathematical dynamic model for a three-phase squirrel-cage induction motor is described to evaluate, via microcomputer, stator winding, rotor winding, stator core and rotor core instantaneous ...
Winding distribution effects on induction motor rotor fault diagnosis
(Elsevier, 2013-10)
The sidebands around stator currents harmonics as a potential tool for supporting the diagnosis of rotor faults in induction motors are analyzed in this paper. The presence of broken bars introduces high frequency components ...
Management of a Dual-Bus AC+DC Microgrid based on a Wind Turbine with Double Stator Induction Generator
(World Scientific, 2021-12-22)
The topology and management of a sustainable dual-bus, AC and DC, microgrid designed to operate connected to a weak grid is presented. AC+DC hybrid microgrids are a robust and cost-competitive solution for poorly connected ...
