The invention discloses a dual redundancy motor for a blood pump and belongs to the field of motors. The dual redundancy motor for the blood pump comprises a pump shell body, end covers arranged on two sides of the pump shell body, stators fixed in the end covers, a central shaft positioned in the pump shell body and a rotor arranged on the central shaft in a sleeved manner; wherein the two stators are symmetrical about the rotor; each stator comprises a shell rack, spacing blocks, an iron core and a plurality of windings; the plurality of windings are embedded into the shell rack, and the spacing blocks are positioned on one side of the plurality of windings; the shell rack, the spacing blocks and the plurality of windings are fixed in an integrated manner via embedding operation and therefore a flat shape structure is formed; the iron core is connected with the flat shape structure in a detachable manner, and the rotor is positioned between the two spacing blocks. The dual redundancy motor for the blood pump provided in the invention is compact in structure and small in occupied space, the stator windings are fixed firmly and are not easy to deform, and therefore high stability is realized.
