Abstract
The present invention relates to an electromagnetic machine comprising: rotation shaft; a stator comprising a multi-phase winding wire; a mover (rotor 1) comprising the multi-phase winding wire and spaced apart from the stator at a preset interval; and a controller for independently controlling a first magnetic field of the stator and a second magnetic field of the mover (rotor 1). The electromagnetic machine according to the present invention can resolve, by means of the mover (rotor 1) and the wound-type stator that can be independently and actively controlled, a torque issue at start-up or when needed and, thereby, has the effects of producing a maximum driving torque while having a minimum size, and of maximizing efficiency.
