TRANSVERSE FLUX MACHINE

摘要

According to one embodiment, a transverse flux machine includes a stator and a rotor. The stator includes a winding and a first ferromagnetic unit. The winding is wound along a rotational direction of a rotation axis. The first ferromagnetic unit has L (L is integral number) magnetic poles holding the winding. The rotor is rotatable relatively to the stator around the rotation axis. The rotor includes a second ferromagnetic unit having L magnetic poles facing the first ferromagnetic unit. If an order of harmonic component of torque ripple to be reduced is (N×1), (N×2), . . . , (N×(M−1)) (M and N are integral numbers. ML), among L magnetic poles in the first and second ferromagnetic units, a relative position of M magnetic poles along the rotational direction is shifted by θ1 ((180°/N/M)θ1(540°/N/M)) in order.
