Abstract:
1. A magnetic transmission assembly, comprising: a rotor, having a plurality of poles, wherein the poles of the rotor have R pole pairs; a stator, sleeved coaxially with the rotor, and having a plurality of poles, wherein the poles of the stator have ST1 pole pairs; and a magnetically conductive element, disposed between the rotor and the stator, and having a plurality of steel pieces, wherein the magnetically conductive element comprises both PN1 and PN2 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, and PN1−3≦R+ST1≦PN1+3.
