The invention discloses an ultrathin high-power direct current magnetoelectric motor, comprising a transmission shaft, a discal stator component sleeved at the middle section of the transmission shaft, discal rotor components which are respectively arranged at the two sides of the stator component and rotate with the transmission shaft, and an upper end cap and a lower end cap which are respectively arranged at the two sides of the rotor components. The stator component comprises a discal stator frame, a plurality of fan-shaped grooves which are arranged on the stator frame in a ring form, fan-shaped windings arranged in the fan-shaped grooves, and inner clamping rings and outer clamping ring for fixing the fan-shaped windings. The rotor component comprises a rotor plate fixedly connectedwith the transmission shaft, fan-shaped grooves which are arranged on the rotor plate in a ring form, and permanent magnets fixed in the grooves. The surface of the rotor plate, which provided with the permanent magnets, faces the fan-shaped windings. The motor of the invention has the advantages of higher efficiency and energy saving, and the manufacturing, the assembling and the maintenance of the stator winding are more simple, convenient and reliable.
