The rotor includes a shaft, a rotor core coaxially connected to the shaft, at least one tangential magnetic steel, a first axial magnetic steel, and a second axial magnetic steel. The tangential magnetic steel is fixed in the rotor core along a tangential direction of the rotor core, and has first and second magnetic poles. The first axial magnetic steel disposed at one end surface of the rotor core is adjacent to the first pole, and has a third pole facing the rotor core, wherein the third pole and first pole repel each other. The second axial magnetic steel disposed at the end surface of the rotor core is adjacent to the second pole, and has a fourth pole facing the rotor core, wherein the fourth pole and the second pole repel each other.
