A method for manufacturing a laminated core for a motor comprises the steps of: stamping a sheet of a core of a straight form to have a form that a plurality of split cores are connected; laminating sheets of the core perpendicularly; bending the sheets of the core in a round form; and forming a connection caulking part at contact parts of yokes, which are adjacent to each other, of the bended core.


Disclosed is a method of wiring a coil in parallel around a stator having a plurality of teeth, which includes the steps of: winding the coil around a tooth starting from a top or a bottom of the stator; continuously winding the coil around an adjacent tooth when winding on the tooth is completed; cutting an end portion of the coil positioned at either the top or the bottom of the stator; wiring the cut end portion of the coil using a bus-bar; and wiring a neutral point to the other end of either the top or the bottom of the stator.


Disclosed herein is a laminated core for a motor manufactured by laminating sheets of a plurality of cores. The laminated core is formed by connection of a plurality of split cores, yoke parts of the split cores which are adjacent to each other get in contact with each other so as to form a contact part, and a connection caulking part is formed at the contact part.


A stator of a motor having a bus-bar wiring structure according to the present invention includes: a stator core configured of a core base in which a plurality of teeth is formed; an upper insulator coupled to a top of the stator core to insulate the teeth; a lower insulator coupled to a bottom of the stator core; a coil wound around the teeth when the upper insulator and the lower insulator are coupled; and a lower bus-bar housing coupled to a top of the upper insulator and having a plurality of bus-bar insertion units formed to insert a plurality of bus-bars.

Provided is a fan motor that includes: a rotor that is coupled with a shaft to rotate together; a stator that is installed at a position facing the rotor; a first bracket on a central upper portion of which a first bearing insertion space into which a first bearing coupled to an upper portion of the shaft is inserted is formed; a second bracket which is hermetically coupled to the first bracket and on a central lower portion of which a second bearing insertion space into which a second bearing coupled to a lower portion of the shaft is inserted is formed; a first bearing cover that covers the first bearing insertion space; and a second bearing cover that covers the second bearing insertion space and has an accommodation space formed to extend to the central lower portion.


Disclosed is a variable magnetic flux motor having rotor in which two different kinds of magnets are embedded. The variable magnetic flux motor includes: a rotor; a stator located inside of the rotor; and magnets including first magnets and second magnets mounted at outer perimeter of the rotor, four pairs of second magnets being arranged by a right angle based on the rotor, a plurality of unit rotor cores being arranged between each of the four pairs of the second magnets, each of the four pairs of the second magnets is facing each other, wherein an amount of magnetic flux of the second magnets is regulated through a difference in a coercive force generated between the first magnets and the second magnets.


The motor according to the present invention is characterized by including a stator core having an upper insulator and a lower insulator combined with an upper portion and a lower portion thereof; a housing manufactured by placing the stator core in an insert injection mold, the housing being formed by a resin molding having at least one upper leg integrally formed in the upper portion thereof; a rotor located inside the stator core of the housing and rotating, the rotor being combined with the housing by having a shaft penetrating into a center portion thereof; and at least one lower leg formed as a separate member from the housing so as to be combined with the lower portion of the housing.
