| titleOfInvention | A kind of two-freedom Lorentz force outer rotor sphere magnetic bearing |
| abstract | The invention discloses a kind of two-freedom Lorentz force outer rotor sphere magnetic bearing, including coil, every magnetic boss, stator sphere magnetic guiding loop, every magnetic screw, epoxide-resin glue, mounting seat, sphere magnet steel, magnetism-isolating loop, rotor magnetic guiding loop, rotor locknut and rotor sleeve, two pairs of coils are respectively used to magnetic bearing radial direction X and Y deflection control, two pairs of coils are fixed on stator sphere magnetic guiding loop by epoxide-resin glue, sphere magnet steel is located at coil radial outside, sphere magnet steel Internal Spherical Surface leaves certain spherical shell gap with rotor magnetic guiding loop spherical outside surface, forms air gap.As a result of spherical shell shape air gap, rotor can overcome the less shortcoming of existing cylindrical air gap Lorentz force magnetic bearing deflection angle with wide-angle deflection.In addition, during rotor deflection to any position, the Ampere force that hot-wire coil electric current is produced is tangent with sphere where coil all the time, i.e. the arm of force of the couple of the Ampere force composition of each pair coil is constant, so as to improve the control moment precision of Lorentz force. |
