The invention relates to a driving motor for a heart assisting device. The driving motor comprises a shell, a stator, a rotor and a rotating shaft, wherein the shell is cylindrical, and the diameter of the shell is smaller than the inner diameter of a femoral artery or an aorta; the stator is in a hollow cylinder shape, is coaxially arranged on the inner wall of the machine shell, and comprises a stator iron core of a toothless structure and a hollow cup type winding. The stator iron core comprises an iron-based amorphous alloy iron core, an epoxy resin coating is arranged on the inner wall of the iron-based amorphous alloy iron core, and the epoxy resin coating is used for performing electrical isolation and volume compensation on the iron-based amorphous alloy iron core; the rotor is in the shape of a center-through column, and the rotor is coaxially arranged in the stator in a penetrating manner; the winding comprises a cup-shaped winding and is arranged between the stator and the rotor; the rotating shaft
