摘要： According to one embodiment, a rotating electrical machine includes an annular winding, L (L is an arbitrary integer) stator magnetic poles, and L rotor magnetic poles having the same polarity. The L stator magnetic poles are disposed apart from each other in a rotational direction and facing the winding. The L rotor magnetic poles have the same polarity as each other. The L rotor magnetic poles are disposed apart from each other in the rotational direction and configured to face the L stator magnetic poles If an order of the fundamental wave component of a torque pulsation is N, M (M≦L) distances between centers of the adjacent poles between pole centers in one set of either the L stator magnetic poles or the L rotor magnetic poles are combinations of (Θ, Θ+Θ1/M, Θ+Θ1×2/M, . . . , and Θ+1×(M−1)/M), and Θ1 satisfies the relationship (180°/N)

摘要： A transverse flux machine includes a stator having a circular coil wound in a rotational direction and a rotor arranged to face the first ferromagnet across a gap. The stator has a plurality of first ferromagnets surrounding a part of the circular coil in the rotational direction separately. The rotor is rotatable about a center axis of the circular coil relative to the stator. The rotor has a plurality of second ferromagnets arranged in the rotational direction separately. A first member and a second member are inserted between adjacent ones of the second ferromagnets. The first member and the second member generate two magnetic fields opposite to each other in the circumference direction.
