Original Abstract Submitted

A rotor may include: a rotor shaft; a rotor core attached to the rotor shaft and comprising a plurality of magnet slots and magnets, wherein at least one magnet of the magnets has an elongated cross-sectional shape and is fixed by being pressed against a part of an inner surface defining a corresponding one of the magnet slots of the rotor core. The rotor is configured so that coolant flowing through the rotor shaft reaches a surface of a long side of the at least one magnet that is exposed inward in a radial direction of the rotor core in the corresponding magnet slot and moves along an axial direction of the rotor core.
