The squirrel-cage Induction motors (SCIMs) are approximately 80% of the overall electricity use in industrialized countries. In the agricultural and commercial sectors also, power consumption by high power SCIMs are quite substantial. On an average, the energy consumed by a motor during its life cycle is 40-80 times the initial cost of the motors. Therefore efficiency and power factor (PF) of t...

Abstract The motive of this study is to analyse the characteristics a novel dual‐stator embedded‐pole six‐phase permanent magnet synchronous motor for application electric vehicles. 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...

This paper offers a novel dual-mode double stator wound rotor synchronous machine for variable speed applications. The proposed motor integrates the benefits of both traditional (WRSM) and brushless (BL-WRSM). A constant torque can be attained in maximum per ampere region by operating as WRSM Mode I, power field-weakening it BL-WRSM II. Moreover, due to dual-stator structure, exhibits improved ...

In this paper, a generalized formula is proposed for the selection of number of slots required for n-phase alternative current (AC) machine design and the criterion for selecting the starting points of each phases. The analytical model is verified using a four-pole machine with a 36-slot stator. Each coil of the stator winding of this machine is brought out to a patch board that enables the sta...

The subject of on-line detection and location of inter-turn short circuits in the stator windings of three-phase induction motors is discussed, and a noninvasive approach, based on the computer-aided monitoring of the stator current Parks Vector, is introduced. Experimental results, obtained by using a special fault producing test rig, demonstrate the effectiveness of the proposed technique, fo...

Abstract In this paper, a transient model of the faulty machine is developed. The model is referred to a three phase stator winding, while the rotor has been represented by all the meshes allowing for the representation of various faults. The model is based on coupled magnetic circuit theory by considering that the current in each bar is an independent variable. The model incorporates non-sinus...

Winding inductance is an important parameter in determining the performance of electrical machines, particularly those with large inductance variation. This paper investigates the influence of winding inductance variation on the performance of a three-phase three-stack claw pole permanent magnet motor with soft magnetic composite (SMC) stator by using an improved phase variable model. The windi...

The paper presents analytical studies of the torque motor tape active element. The tape active element is a novel type of a motor's stator organization, where the conventional winding is replaced by a tape winding. Given the operation principle of proposed active element; its torque characteristics are then computationally found with using the finite element method (FEM). The results show the p...

A method of induction motor diagnostics based on the analysis of three-phase instantaneous power spectra has been offered. Its implementation requires recalculation of induction motor voltages, aiming at exclusion from induction motor instantaneous three-phase power signal the component caused by supply mains dissymmetry and unsinusoidality. The recalculation is made according to the motor know...

This paper discusses the application of MultiLayer Feed Forward Neural Network (MFNN) for the differential protection of the turbogenerator based on pattern classification. The cases of all the possible internal faults in the stator of the generator with lap winding have been simulated using Modified Winding function Approach. The simulated fault currents in the phases and their parallel paths ...
