<P>PROBLEM TO BE SOLVED: To provide a motor that prevents deformation of extensions due to the load such as of molding pressure, and to provide a pump having the motor and an apparatus having the pump. <P>SOLUTION: A motor 8 has a stator 17 and a rotor 9. The rotor 9 has a circumferential surface along a rotational direction thereof. The stator 17 has: a core 19 that is formed by laminating a plurality of plate-like bodies; coils 18 that are formed by winding lead wires around the core 19; and an insulating portion 27 that insulates the core 19 from the coils 18. The core 19 has magnetic pole portions 22 facing the circumferential surface. Each of the magnetic pole portions 22 has extensions 25 at respective ends in an axial direction Ax of a rotational axis of the rotor 9. The motor 8 also has a deformation preventive portion 39 that prevents deformation of the extensions 25. <P>COPYRIGHT: (C)2013,JPO&INPIT |
