A Transverse Flux Generator With a Single Row of Permanent Magnets: Analytical Design and Performance Evaluation

This paper presents the experimental results from a transverse flux generator with a modified structure. The new transverse flux generator enjoys a coreless rotor leading to a reduction in manufacturing complexity, as well as a decrease in the mass of the rotor, which in turn results in a better active power density. On the other hand, the number of permanent magnets used in the proposed machine is half of that utilized in a conventional transverse flux generator, which reduces the construction cost, especially in large-scale transverse flux generators. Moreover, in the proposed machine, the leakage flux originating from the inactive magnets would considerably be less than that in conventional machines. Besides, this paper demonstrates an analytical model based on the magnetic equivalent circuit for calculation of the proposed generator parameters. Finally, a transverse flux generator is prototyped and tested.
