A stator-less electric motor (86) for an MRI system (10) is provided. The stator-less electric motor (86) includes: a body (88); a rotor (90) connected to the body (88) to be rotatable; and at least one coil winding (92) disposed on the rotor (90). The at least one coil winding (92) is arranged so as to rotate the rotor (90) when energized via an electrical current in the presence of a magnetic field (94) generated by a magnet assembly (56) of the MRI system (10). MRI 시스템(10)을 위한 스테이터리스 전기 모터(stator-less electric motor)(86)가 제공된다. 스테이터리스 전기 모터(86)는 본체(88), 본체(88)에 회전 가능하게 연결되는 로터(90), 및 로터(90) 상에 배치되는 적어도 하나의 코일 권선(coil winding)(92)을 포함한다. 적어도 하나의 코일 권선(92)은, MRI 시스템(10)의 자석 조립체(56)에 의해 생성되는 자기장(94)의 존재 시에 전류를 통해 통전될 때에 로터(90)를 회전시키도록 구성된다.
