Abstract
An electric rotating machine according to an embodiment includes a stator, and a rotor that is rotatable about a rotational center. The stator includes a winding having an annular shape with the rotational center, a first core, and a second core. The first core surrounds a part of the winding, and has a pole face to which a magnetic flux is input in a first direction, and a pole face from which the magnetic flux is output in the first direction. The second core surrounds a part of the winding, and has a pole face to which a magnetic flux is input in a second direction, and a pole face from which the magnetic flux is output in the second direction. The rotor is positioned spaced from the first core and the second core, and is rotatable about the rotational center, relatively with respect to the stator.
