ABSTRACT:
An apparatus for producing high-speed rotation has a rotary shaft integrally having a first rotor with magnetic anisotropy, and a rotary sleeve disposed around the rotary shaft. The rotary sleeve has a first stator surrounding to the first rotor and integrally has a second rotor having magnetic anisotropy. The first stator has a field winding for magnetizing the first rotor in a predetermined direction. This winding is also an armature winding because it undergoes high-speed rotation with the second rotor. The rotary sleeve is received in a housing which has a second stator surrounding the second rotor. The second stator has a field winding for magnetizing the second rotor in a predetermined direction and for producing high-speed rotation of the second rotor. By analogy, the housing can become a further rotary sleeve, constructed similarly to the above-mentioned rotary sleeve.
