ELECTRIC PUMP

摘要

PROBLEM TO BE SOLVED: To reduce cost and to miniaturize a device itself by reducing the number of parts and to simplify an assembling process by mounting it on a printed wiring board. SOLUTION: An electric pump is constituted of a coil 11 to generate a rotating magnetic field and an impeller 10 having a permanent magnet 12, and it rotates the impeller 10 by receiving the rotating magnetic field. It becomes possible to miniaturize the electric pump and to simplify an assembling process by arranging the coil 11 on the printed wiring board 17 and to provide freedom on mounting by miniaturization of the device.
