The article presents a concept for a new design of the well-known Transverse Flux Machine (TFM) made with the use of a flat core used in classical electrical machines. The proposed design was first analytically verified and was subsequently verified using the finite element method, which fully corroborated the results. The simulations show that a set of three single-phase TFM machines with slotted flat rotor yokes generates a torque over three times greater than that of an induction motor and twice as large as Fractional Slot Concentrated Winding—Permanent Magnet Synchronous Machines (FSCW-PMSM). The performed comparative calculations confirmed that the torque generated by machines operating on principles similar to TFM can generate a torque much greater than those currently in common use.

And Performance

In automotive applications, the requirements for the electrical machines are about performance and reliability - the permanent magnet synchronous machines ensure these requirements are fulfilled. The approach of the present paper is to analyze the permanent synchronous machines suited for the integrated starter-alternator (ISA) applications. The study design requires some analytical, followed by a numerical analysis and also a finite element method in order to achieve the performances of the machine. The operation modes of an ISA system and the constraints for an electric machine acting as an ISA are detailed. Finally a model for a ISA hybrid vehicle, developed in AMESim is presented and the results of a simulated drive cycle are presented.

The Given

This paper presents analysis and study of the single-phase transverse-flux machine. The finite element method results of the machine are compared with the laboratory measurements to confirm the accuracy of the computer model. This computer model is then used to investigate the effect of the machine’s geometry on its output characteristics. Parametric analysis of the machine is carried out to find the optimal air-gap diameter at which the cogging torque of the machine is minimal. In addition, the influence of the coil cross-section on the torque and output power characteristics of the machine is investigated and discussed.

Fractional Slot

Star-connected and delta-connected circuits of fractional slot concentrated winding in permanent magnets synchronous machines (SMPM) are described in the paper. Advantages and drawbacks of these winding circuit types are shown. Investigation results on the characteristics degradation in the machines with fractional slot concentrated windings owing to delta-connected circuit are presented.
