Zusammenfassung:PROBLEM TO BE SOLVED: To provide a rotor for electric pump which can reduce the weight of a magnet part, though the magnet part can be easily formed. SOLUTION: The rotor is provided with the magnet part 9 which is made in ring form and where N poles and S poles are oriented aeolotropically about poles so that they may appear alternately in its circumferential direction. The inner perimetrical part of the magnet part 9 is made in the shape of a polygon where its corner 12 is positioned at a magnetic concentration part 11 where magnetism concentrates in the circumferential direction of the magnet part 9.
