The invention provides an electric driver and an electric power steering device. The electric driver includes: a first end cap which includes a first shaft hole and a plurality of first fixing parts; a second end cap which comprises a second shaft hole and a plurality of second fixing parts corresponding to the plurality of first fixing parts; a plurality of connecting parts which are connected between the corresponding first fixing parts and the second fixing parts, so that the first end cap is fixed relative to the second end cap and is separated from the second end cap; a rotor which is arranged on a rotating shaft, wherein the rotating shaft extends and penetrates through the first shaft hole and the second shaft hole; and a stator which is mounted between the first end cap and the second end cap and disposed around the rotor. The rotor comprises a plurality of axially extending slots, and magnets are arranged in the slots. The electric drive and the electric power steering device have the advantages of being simple in structure, easy to manufacture, convenient to install and the like, and the manufacturing cost can be reduced while the structural stability is ensured.
