An electric motor according to one exemplary embodiment disclosed herein includes a frame, a stator provided with a stator core inserted into the frame in a contacted or coupled manner, and a stator coil, and a rotor rotatably disposed to be rotatable with respect to the stator, characterized in that the frame has a smaller specific gravity and a greater thermal deformation value than the stator core, and an anti-separation unit is provided between the frame and the stator core to prevent the frame and the stator core from being spaced or separated from each other due to different levels of thermal deformation upon a temperature change. Accordingly, the coupling between the frame and the stator can be firmly maintained irrespective of a temperature change. |
