A motor for a pump is provided to improve rotating efficiency by installing a first magnet interval maintenance unit in the front of a rotor and installing a second magnet interval maintenance unit repelled to the rotor. A motor for a pump comprises: a pump body(110) with an electromagnet; a rotating case(131) coupled inside the electromagnet; a rotary shaft(132) with a rotor(133) which is coupled on the center of the rotating case; a first magnet interval maintenance unit(235) coupled by interposing a protrusion inside the rotating case; a second magnet interval maintenance unit(236) installed to be faced with the first magnet interval maintenance unit by interposing a protrusion; and a bearing(137) coupled inside the rotating case.
