A stator module and a motor including the stator module are provided. The motor includes a stator and a stator module. The rotor includes a rotor core and a plurality of rotor poles arranged around a circumference of the rotor core, each generating a magnetic flux. The stator module includes a first stator and a second stator disposed coaxially with each other, each being rotatable in a circumferential direction and each having a coil wound thereon, and a rotation driving unit which controls a rotation of the first stator and the second stator through the same angle in opposite directions, thereby controlling a flux linkage of a rotor according to the rotational angle of each of the first stator and the second stator.

Stator module and motor including the same

A rotor and a motor are provided in which the q-axis inductance is increased and the leakage of magnetic flux is prevented to ensure high power operation at high level driving speeds. The rotor includes a rotor core, which is formed at the center thereof with a hole coupled to a shaft, and a module configured to be coupled to the rotor core and comprises a pair of first permanent magnets, which are space apart from each other, and a first connection part connecting ends of the first permanent magnets to each other.
