The invention discloses a lorentz-force axial
magnetic bearing of an outer rotor. The lorentz-force axial
magnetic bearing mainly comprises two parts, namely a
stator system and a rotor
system, wherein the
stator system mainly comprises a skeleton, an upper winding, a lower winding,
epoxy resin glue, magnetic-conductive seats and a
stator locking nut; the rotor system mainly comprises upper magnetic steel, lower magnetic steel, a magnetic-isolated ring, a magnetic-conductive ring, a rotor locking nut and a sleeve. The lorentz-force axial
magnetic bearing disclosed by the invention has the beneficial effects that the windings are directly provided with the magnetic-conductive seats with good heat-conductive performances, so that the
copper loss and the rotary loss of the windings can be quickly conducted out by the magnetic-conductive seats; since a single-edge magnetic steel structure is adopted, the lorentz-force axial magnetic bearing has the advantages of simple structure, good
linearity,
high bandwidth, good
heat conducting performance and the like, the structure reliability of the axial magnetic bearing is improved, and simultaneously the temperature rise of the magnetic bearing is reduced, so that the lorentz-force axial magnetic bearing can be used for non-contact suspension supporting such as a magnetic suspension
momentum wheel and a magnetic-suspension
gyroscope.
