摘要： The rotary member carrying the X-ray radiation unfit and the X-ray detection unit and rotated around a subject is used as the rotor. The rotor is provided with a rotor core and a plurality of conductors connected to the core. The stator has at least one set of stator core and stator winding, the at least one set of stator core and stator winding being adapted to clamp the rotor and arranged at opposing positions. A three-phase AC current is supplied to the stator winding to generate a rotating magnetic field to rotate the rotor and thereby rotate the rotary member at high speed. Because the scan time can be reduced, the X-ray CT scanner can scan such moving organs as heart.
