Abstract
A fan module assembly includes at least one a rotatable fan () having blades () with tips of blades being joined by an annular fan band (). An electrically conductive squirrel cage () is associated with the fan band to rotate therewith. Flux receiving structure () is associated with the fan band. A shroud () has a shaft () with the fan being associated with the shaft so as to rotate about the shaft and with respect to the shroud. Control structure () is mounted stationary with respect to the shroud generally adjacent to a portion of the fan band. The control structure is constructed and arranged to generate a changing magnetic field, generally at the radius of the fan band, which interacts with the flux receiving structure and the squirrel cage to cause the fan to be driven by tangential force.
