Abstract:
A skeleton type brushless motor comprising:a rotor having a rotational shaft in a center thereof; a first stator core including a first semicircular inner profile defined between first and second ends of said first stator core; a second stator core including a second semicircular inner profile defined between first and second ends of said second stator core, wherein said second stator core is connected to said first stator core such that said second semicircular inner profile faces to said first semicircular inner profile and a first separation space exists between said first end of said first stator core and said first end of said second stator core, and a second separation space exists between said second end of said first stator core and said second end of said second stator core; a coil winding unit connected to at least one of said first and second stator cores; and a coil wound on said coil winding unit, wherein outer profiles of said first stator core and the second stator core near the first separation space or the second separation space, protrude outwardly away from said rotational shaft as said outer profiles progress toward the end of the first stator core or the second stator core.
