Abstract
Provided is an axial gap type motor employing a non-rare earth magnet, and a water pump using same. The axial gap type motor for a water pump (EWP) comprises: a rotor rotatably supported on a fluid flow passage between a pump cover and a body case; a stator arranged in a lower space formed by the body case and an upper cover, so as to generate a rotating magnetic field, thereby rotating the rotor; and a partition arranged on the body case in order to separate the rotor from the stator. The rotor can use a ferrite magnet, which is a non-rare earth magnet.
