Transverse flux machines (TFM) can be designed with high pole numbers, so they are very useful in directdrive systems with high torque density. Although many TFM models have been proposed to date, no detailed classification and comparison has been made before. Conventional TFMs have a high power and torque density, but low power factors and high cogging torques have prevented them from being widely used. However, especially with the new disk type TFMs proposed in recent years and the methods developed, these drawbacks have been reduced. In this paper, the TFMs proposed in recent years have been classified and their performances in terms of power factor, cogging torque, torque density, and efficiency have been examined. According to the results of this review, the performances of the new generation TFMs are competitive. Especially double-sided disk type TFMs are seen as an important topology with their high magnet utilization and flexibility in design.

“…Therefore, the flux density of the air gap is higher in the same magnet volume [42]. When the pole structure is examined especially in the disk type TFMs, using the arc-shape poles increases the power factor relatively [25]. However, there is a slight decrease in efficiency and torque density.…”

“…To further improve the torque density, and nullify radial forces on the rotor shaft, double stator SRM is presented in [19][20][21]. The E-core stator structure has also been widely adopted in PM transverse flux [22], PM veriner [23], and PM flux switching machines [24][25][26][27][28][29][30][31][32][33].…”

This study proposes a modified structure of the E-core permanent magnet (PM) assist switched reluctance motor by relocating the PM blades inside the stator core. For this purpose, the PMs are removed from the stator poles and placed slantwise inside the yoke. The proposed yoke-PM assist structure is characterised with higher average torque and a lower torque ripple with respect to the conventional pole-PM assist structure. An analytical approach based on the magnetic equivalent circuit is applied at the preliminary design stage to predict the performance of the motor. Based on the presented analytical modelling, the physical dimensions of the motor are optimised via a genetic algorithm to maximise the motor torque and the overall steady state performance. For further verifications, the finite-element analysis simulation results are verified by the experimental tests on the motor prototype.
