The utility model discloses a two-speed automotive electromagnetic fan clutch. The two-speed automotive electromagnetic fan clutch is mainly characterized in that a circular soft magnetic disc is connected to the outer periphery of a suction end of a transmission disc through circular nonmagnetic members, and a plurality of permanent magnets in clearance fit are distributed and connected to the inner end face of the circular soft magnetic disc and the end face of a fan fixing disc. When the circular soft magnetic disc connected to the outer periphery of the suction end of the transmission disc through the circular nonmagnetic members rotate to operate in correspondence to the permanent magnets distributed and connected to the end face of the fan fixing disc, the circular nonmagnetic members fully function in mutually isolating lines of magnetic force left when electromagnets stop operating from lines of magnetic force generated by the permanent magnets. Therefore, operating magnetic force generated by the cir
