The present disclosure relates to an electric motor, and a compressor having the same. The electric motor includes a stator, and a rotor. The rotor includes a rotation shaft, a rotor core, and a plurality of permanent magnets. The rotor core includes permanent magnet insertion portions each formed therethrough in an axial direction so that the permanent magnet is inserted, and slots each formed through the rotor core in a manner that a core area of a front portion of a d-axis is smaller than a core area of a rear portion of the d-axis in a rotating direction of the rotor when an outer core part of the permanent magnet insertion portion is divided with respect to the d-axis. Accordingly, a decrease in inertia can be suppressed and an occurrence of vibration and noise due to Magnetic Pull Force (MPF) can be prevented.
