Abstract: PURPOSE: An axial guide force increasing type radial magnetic bearing is provided to reducing weight by removing additional axial magnetic bearing and to improve energy efficiency. CONSTITUTION: A non-magnetic body(5) is inserted between an iron core(1) of a stator and a stratified iron core(3) of a rotator to generate stable axial direction guide force as two points. Eddy current is generated because the stratified iron core of the rotator rotates in high speed. Therefore, lifting force is reduced by eddy current and temperature of the iron core of the rotator and braking force is generated against rotating force. Therefore, a silicon steel sheet which is thinner than 0.3 millimeters is used as the iron core.
