Magnetic gear based rotating-linear variable speed motor
2016
The invention discloses a magnetic gear based rotating-linear variable speed motor. The motor comprises a stator armature, a high-speed permanent magnet rotor, a magnetic field adjusting apparatus and a low-speed permanent magnet mover, wherein the stator armature comprises a stator iron core and an armature winding; the high-speed permanent magnet rotor comprises a rotor iron core and a permanent magnet built in the iron core; the magnetic field adjusting apparatus comprises irregular bodies formed by ferromagnetic materials and non-ferromagnetic materials that are arranged at intervals; the low-speed permanent magnet mover comprises a mover iron core and a permanent magnet adhered to the surface of the iron core. The motor can be taken as the shunt-wound coupling of a permanent magnet synchronous motor and a rotating-linear conversion type magnetic gear.
