PROBLEM TO BE SOLVED: To provide a rotary pump easily manufactured and providing high output. SOLUTION: A rotor 20 is rotatably disposed inside of a pump case 10. In a peripheral edge part of the rotor 20, a plurality of magnets 24 are disposed on the same circumference around a rotational axis 21 as a center, at intervals. Outside the pump case 10, a plurality of coils 30 are disposed on the circumference opposed to the magnets 24. The rotor 20 is constituted of nonmagnetic material. In the pump case 10, an opposed area 16 opposed to the magnets 24 is constituted of high-resistance nonmagnetic material. COPYRIGHT: (C)2011,JPO&INPIT
