Initial experimental verification of a compact permanent magnet transverse flux machine in a sector configuration

Abstract

Φ Abstract -Flux concentrated permanent magnet transverse flux machine (FCPM-TFM) that is designed to achieve a compact design for in-wheel applications, has been set under test experiments to verify the published investigations that are demonstrated in [1-6] and achieved through many computer simulations via using FLUX3D, a 3D finite element (FE-) package from Cedrat. The study in this paper includes generator and motor operations of the FCPM-TFM. Starting with generator electromotive force i.e., back EMF test, where the machine is operated as a generator for different speeds. The induced voltage waveform and cogging torque have been estimated via introducing 2D grids in certain positions of a two pole pitch segment and compared to the outcome of the software. The flux linkage has been examined by using an AC method, while including core losses, where the effects of saliency are illustrated. Motor operation is done through full block control. The measured quantities have been compared to the simulations results.

Transverse flux permanent magnet motor with double-C stator hoops and flux-concentrated rotor for in-wheel drive electric vehicle

“…The main flux moves forward in a spiral through both stator hoops and rotor irons on the arrow line directions. Each phase of the TFPMM has a single electric circuit couples with two magnetic circuits, which distinguishes from one electric circuit couples with one magnetic circuit machines referred in [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Another characteristic is to bring about flux-concentration by employing the traditional siliconsteel lamination instead of soft magnetic composite (SMC), which has lower magnetic permeability and lower saturation flux density while price and eddy current loss are significantly high.…”

“…Transverse flux permanent magnet motor (TFPMM) is suitable for in-wheel motor applications due to its high torque capability [1][2]. The design of such a machine with an external rotor is favorable against conventional induction machines as IPM and SRM due to the high output torque in conjunction with low heat losses [3].…”

Influence of Concentric Saddle Shaped Coils on the Behavior of a Permanent Magnet Transverse Flux Machine with Segmented Construction

“…It should be pointed out that a domain can contain meshed and non-meshed coils at the same time. Therefore, equation (10) changes to (14). (14) where corresponds to meshed conductors and to the field created by non-meshed coils.…”

“…Through utilization of non-meshed coils, the induced flux and flux linkage in the coils due to PMs and armature current can be studied, this was already investigated in [12][13][14].…”

A Novel Transverse Flux Permanent Magnet Generator With Double C-Hoop Stator and Flux-Concentrated Rotor

“…RANSVERSE flux permanent magnet generator (TFPMG) possesses decoupled electric load and magnetic load, as well as the prominent capability of carrying considerable poles, to obtain high power density [1]- [3]. Many new TFPMGs with attractive structures have been proposed for wide speed operation in many areas [4]- [8].…”
