A noiseless motor pump is provided to prevent the latent heat of a motor main body by passing a waterway through the coil center of the motor main body and prevent the circulation noise of the water by discharging water inside a pumping part. A waterway(6) is installed at a motor main body(1a) and passes through each coil(2) center. An insulating barrier is formed in a radial shape around a vent(62) of the waterway. A plurality of electromagnets(51) of a stator(5) are formed in a flabelliform by being divided respectively with the insulating barrier. A plurality of permanent magnets(71) of a rotor is separated with the insulating barrier and is formed in a flabelliform. An impeller(8) is formed integrally with a rotor shaft formed at the center of the rotor. A pumping part(1b) is protruded in the stator of the motor main body. Ceramic pins(9a,9b) put into both ends of the rotor shaft.
