Based on the fact that the three-phase induction machine proves higher performance under six-phase supply, which was demonstrated in Part 1 of the paper, this work investigates the fault-tolerance capability of the six-phase structure with asymmetrical configuration (30° phase shifting both for space and time conditions). It is taken into discussion the cut-off of one, two and three phases respectively...
A comparative study of a 5 phase PMSG with classical distributed winding and one with fractional slot winding is presented in this paper. Finite element analysis has been used for both models in order to estimate there performances. Two initial conditions have been considered: keeping the same volume of permanent magnet and the same total slots section for stator winding. The main goal was to design...
The paper presents a comparative analysis of a three-phase induction motor that operates connected to the industrial supply system and separately to a six-phase supply source, as well. The design of the electric machine is made in such a way to fit for both situations. The six-phase supply, which is composed of two distinct three-phase systems, was configured for two cases: 30° and 60° phase shifting...
This paper presents the analysis of using segmented permanent magnet instead of single pole units on a synchronous generator. The main reason of using such solutions is the fact that smaller, simple shapes permanent magnets with standardized dimensions can easily be found on the market at low costs.
Design aspects and FEM simulation results of a six-phase induction motor consisting of two three-phase single tooth concentrated windings with a 30° shift between, and an external rotor are presented in this paper. The main goal is to find a suitable candidate for electric vehicle applications which require simplified manufacturing process, reduced fabrication costs, and achieving high efficiencies...
An efficient approach strategy for 3D FEM simulation of a toroidal transformer is presented in this paper. The main goal is to find a suitable solution for toroidal transformers analysis, in terms of achieving more accurate results with less time consuming methods.
This paper presents a FEM-based analysis of two permanent magnet fractional slot machines that have the same stator structure with 9 slots but a different number of rotor poles, which is 8 and 10 respectively. The results have to point out the advantages and drawbacks of each structure. Specific electromagnetic quantities have been investigated such as flux density and back emf, but also cogging torque...
This paper presents a complex study of the performance developed by an outer rotor induction motor with multipole stator winding. The novelty of the proposed structure consists in the replacement of the regular lap winding with a ring type one, which allows a higher flexibility in changing the number of pole pairs. The purpose is mainly to obtain a superior torque capability by changing the synchronous...
This paper presents the results of an optimization process on a three phase squirrel-cage induction motor designed for mining applications. In order to achieve the imposed working characteristics (limited start-up current and convenient torque values), deep rotor bars and double cage solutions have been considered and analyzed. For this aim, the finite element method (FEM) has been used. The obtained...
