<p>According to the present invention, a rotor for an electric motor may comprise: a rotor body rotating about a motor rotating shaft; multiple embedded magnets embedded in the circumferential side of the rotor body, which is relative to the motor rotating shaft; and multiple main holes formed into a trapezoid or an arc-shaped band in one portion of a main region between the embedded magnets and the motor rotating shaft. The rotor may further comprise multiple crescent-shaped holes formed in a region between the main holes such that the crescent-shaped holes are formed in a circumferential direction in the region closer to the circumference than the main holes.</p> |
