ABSTRACT:
A rotor of an electric motor includes lamination core formed by laminating a plurality of individual cores, and at least one pair of magnet members that generate rotating torque by electromagnetic interaction with a stator, are provided at the lamination core such that a magnetic sensor can sense magnetic flux, and have magnetic poles opposite to each other, such that a position of the rotor of the electric motor can be accurately detected and a process of manufacturing the electric motor can be simplified.
