The permanent magnet synchronous motor (PMSM) has been used in electric propulsion and other fields. However, it is prone to the stator winding inter-turn short-circuit, if no effective measures are taken, ship’s power system will be paralyzed. To realize intelligent diagnosis of short circuits, this paper proposes an fault method based on improved variational mode decomposition (VMD), multi-sc...

Single-phase induction motors have a wide range of domestic and industrial applications. These motors have a squirrel cage rotor and their stator usually has two windings: main and auxiliary. The use of auxiliary winding in the structure of single-phase induction motors creates two unbalance and asymmetric phases. This causes to increase the spatial harmonics of the field in the air gap, and al...

The aim of this study is to employ the wavelet technique for the diagnosis of open-circuit and short circuit faults in the dc link of induction motor drive. The symlet wavelet is selected as the wavelet base to perform stator current analysis during faults. In this method, the stator currents are used as an input to the system. The MATLAB software is used to process discrete wavelet transform (...

The design of a fully superconducting wind power generator is influenced by several factors. Among them, low number pole pairs desirable to achieve AC losses in the stator winding, which greatly influences cooling system and, consecutively, efficiency entire plant. However, it has been identified that tends increase its output voltage, turn creates challenging conditions for necessary electroni...

Winding function method (WFM) provides a detailed and rather simple analytical modeling and simulation technique for analyzing performance of faulty squirrel-cage induction motors (SCIMs). Such analysis is mainly applicable for designing on-line fault diagnosis techniques. In this paper, WFM is extended to include variable degree of magnetic saturation by applying an appropriate air gap functio...

A comparative analysis two separate topologies, namely, dual stator and single rotor surface‐mounted motor, accomplished illustrate performance superiority proposed motor. Furthermore, optimal designing design metho...

Stator interturn faults are one of the most common faults occurring in induction motors. Early detection of interturn short circuit is important to reduce repair costs. Axial leakage monitoring, zero-sequence components, negative sequence current, and motor current signature analysis have been used for fault detection in early states. In the paper, the instantaneous power signature analysis tec...

In this paper first a current predictive method for single open-phase fault detection in a three phase drive with a permanent magnet synchronous machine is presented. The proposed method is based on a predictive stator current calculation. For each sampling interval the difference between the actual stator current and its predicted value in a previous sampling interval is calculated. To identif...

Since the induction motor drives have gained its popularity among regulated drives area, the great effort is put on increasing their efficiency. The use of predictive algorithm to control their speed is becoming a popular approach that preserves high efficiency. This paper presents implementing predictive control on the dSPACE DS1103 system, where the dSPACE is the control part of the system, d...
