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)<Θ1<(540°/N) in the notation of electrical angle.
