摘要： A motor having a magnetic bearing comprises a base formed with a bearing seat; a stator fixed to the base; a rotor provided with a rotation shaft and rotatable with respect to the stator by magnetic forces generated from excitation; a bearing fixed to the bearing seat of the base for receiving the rotation shaft of the rotor; and a magnetic element pair including a first element and a second element. The first element is telescopically interference-fitted on the rotation shaft, the second element is fixed relative to the bearing seat and lets the rotation shaft insert therethrough, and a magnetic force is generated between the first element and the second element. When the rotor rotates and an external force acts on the rotor in a direction, a magnetic force between the magnetic element pair counteracts the external force to achieve an axial positioning effect and avoid the contact wear.
