| 摘要 |
This invention relates to a magnetic gearbox, comprising: an inner rotor having a first plurality of magnetic flux sources; an outer rotor having a second plurality of magnetic flux sources; and, a modulator having a plurality of pole pieces positioned between the first and second magnetic flux sources and separated from each by an air gap, wherein upon relative rotation of the inner rotor, outer rotor and modulator the first and second magnetic flux sources and pole pieces are arranged to provide a modulated magnetic field in the air gap adjacent each rotor; wherein either or both of the modulator and inner rotor include at least one nozzle for directing fluid radially across the respective air gap so as to impinge on the adjacent rotor or modulator. |
