The present invention relates to an electric motor and an electric vehicle having the same. The electric motor of the present invention includes: a stator having a stator core and a stator coil wound around the stator core; and a rotor disposed to be rotated while having a predetermined gap with respect to the stator. The stator core includes a rotor receiving hole in which the rotor is accommodated; a plurality of slots alternately formed around the rotor receiving hole; and a plurality of teeth. A slit penetrated in an axial direction so that the cross-sectional area of a magnetic body of each of the plurality of teeth can be reduced is provided to each of the plurality of teeth. Accordingly, the magnetic flux density passing through the teeth can be increased to suppress the harmonic magnetic flux from passing through the teeth.

    본 발명은 전동기 및 이를 구비한 전기차량에 관한 것이다. 본 발명의 전동기는, 스테이터코어 및 상기 스테이터코어에 권선되는 스테이터코일을 구비한 스테이터; 및 상기 스테이터에 대해 미리 설정된 공극을 두고 회전 가능하게 배치되는 로터;를 포함하고, 상기 스테이터코어는, 상기 로터가 수용되는 로터수용공; 상기 로터수용공의 둘레에 교호적으로 형성되는 복수의 슬롯; 및 복수의 티스;를 구비하고, 상기 복수의 티스에는 상기 복수의 티스의 자성체의 단면적이 각각 감소될 수 있게 축방향으로 관통된 슬릿이 각각 구비되게 구성된다. 이에 의해, 티스를 통과하는 자속밀도를 증가시켜 고조파 자속이 티스를 통과하는 것을 억제시킬 수 있다.
