Abstract
This paper presents a drive method with pulse currents of a transverse-flux motor having small cogging torques suppressed by short circuits of permanent-magnet fluxes for reducing the torque ripples. This paper also describes numerical analysis results of the flux linkage and torque characteristics for the rotor position for each drive method. The results indicate the drive method with pulse currents can generate larger torques and lower torque ripples compared with that with the same-amplitude sinusoidal currents.
