US 2011/0215667 A1 · MAGNETIC TRANSMISSION ASSEMBLY

Abstract

A magnetic transmission assembly is adapted to integration with a motor or generator. The magnetic transmission assembly includes a rotor, a stator, and a magnetically conductive element. The rotor and the stator are sleeved coaxially and respectively have R and ST1 pole pairs. The magnetically conductive element is located between the rotor and the stator, and has steel pieces. When the magnetically conductive element is actuated, the magnetically conductive element selectively enables PN1 or PN2 steel pieces to be corresponding to the rotor and the stator. The steel pieces corresponding to the rotor and the stator interact with magnetic fields of the R and ST1 pole pairs to generate a predetermined variable-speed ratio. The magnetic transmission assembly can be integrated into the motor, so as to improve the drive power density.
