A motor, possibly for a pump, has a housing, a first member disposed within the housing and mounted on an inner wall of the housing, and a second member rotatably disposed within the housing and having a rotary shaft. A thrust bearing is mounted within the housing in order to support a first end of the rotary shaft in an axial direction of the rotary shaft. A core and coils wound around the core are provided on one of the first and second members. A set of magnets is provided on the other of the first and second members. The core and the set of magnets are positioned such that a magnetic force is produced in an area where a magnetic flux is generated between the core and the set of magnets. The magnetic force causes the second member to move toward the thrust bearing.
