A radial magnetic bearing is constructed by using a plurality of electromagnets in the circumferential direction each consisting of an iron core made of laminated thin silicon steel plates and a winding wound around the magnetic poles of the iron core. ,
A stator core of a radial magnetic bearing, characterized in that a constant gap is provided between adjacent electromagnets, and a non-magnetic material is interposed in this gap to fix the adjacent electromagnets to each other. 2. The stator core of a radial magnetic bearing according to claim 1 of the utility model registration claim, wherein the number of electromagnets is three or more. 3. A stator core of a radial magnetic bearing according to claim 1, wherein the gap between adjacent electromagnets is larger than the gap between the magnetic pole surfaces of the electromagnets and the opposing surface of the rotor supported in a non-contact manner. . 4. The stator core of the radial magnetic bearing according to claim 1, which is either an inner rotor type in which the rotor rotates inside the electromagnet or an outer rotor type in which the rotor rotates outside the electromagnet. 5. A stator core of a radial magnetic bearing according to claim 1, wherein the iron core is made of ferrite material. 6. A stator core of a radial magnetic bearing according to claim 1 of the registered utility model, in which adjacent electromagnets are fixed by brazing. 7. The stator core of the radial magnetic bearing according to claim 1, wherein the fixed portions of adjacent electromagnets extend from the inner diameter portion of the stator forming the magnetic pole face to the outer diameter portion of the stator that contacts the frame. . 8. A stator core of a radial magnetic bearing according to claim 1 of the utility model registration claim, wherein the iron core is E-shaped. 9. The stator core of a radial magnetic bearing according to claim 1, wherein the iron core is C-shaped and the outer peripheral portion extends in the direction of the adjacent electromagnet.
