The invention relates to a horizontal shaft magnetic suspension wind driven generator, comprising a stationery part and a rotating part; the stationery part comprises a radial magnetic bearing stator part, an axial magnetic bearing stator part, a generator stator part, a front protective bearing, a rear protective bearing, a stator shell and a blower tower; the rotating part comprises a blade, a hub, a rotating shaft, a radial magnetic bearing rotor part, an axial magnetic bearing rotor part and a generator rotor part; an axial magnetic bearing is composed of a permanent magnet without a control system, a radial magnetic bearing is a permanent magnet bias magnetic bearing, the permanent magnet provides bias flux density, and control force is adjusted by current; the blower rotor realizes five-freedom-degree stable suspension, can completely eliminate the mechanical friction of the rotating part and the stationery part, reduce starting resisting moment and starting wind velocity of the blower and improve the wind energy utilization rate. All components of the invention have rational and compact layout, the maintenance of the blower can be reduced and the service life is prolonged.
