Brushless Doubly-Fed Induction Machine as a Variable Frequency Transformer

VFT (variable frequency transformer) has been recently used as an alternative to HVDC (high voltage direct current) to control power flow between asynchronous networks. VFT consumes less reactive power than a back-to-back HVDC system, provides faster initial transient recovery, and has better natural damping capability. VFT is simply a DFIM (doubly-fed induction machine) where the machine torqu...

Brushless Doubly-Fed Reluctance Machine Optimization using Reluctance Networks

The Brushless Doubly-Fed Reluctance Machine (BDFRM) is being considered as a viable generator alternative to be used in wind turbines. However, a literature review shows that there is still a lack of researches to define a design procedure to make this machine commercial. This paper aims to address this issue by considering a new BDFRM design method using a reluctance network approach with focu...

Design of permanent magnets to chaoize doubly salient permanent magnet motors for electric compaction

This article proposes and implements a class of chaotic motors for electric compaction. The key is to develop a design approach for the permanent magnets PMs of doubly salient PM DSPM motors in such a way that chaotic motion can be naturally produced. The bifurcation diagram is employed to derive the threshold of chaoization in terms of PM flux, while the corresponding phase-plane trajectories ...

Analysis of Electromagnetic Characteristic of a Novel Doubly Salient Brushless Generator

To develop a fault tolerant machine with the least redundant phases, the inductance model and a nonlinear radial air gap flux density model of a new four-phase doubly salient electromagnetic generator (DSEG) is presented and verified by the finite element analysis (FEA) and experiments result in this paper. With the proposed formulas, a new four-phase 24-slot 18-pole DSEG without cogging torque...
