    Abstract: PURPOSE: A brushless DC(Direct Current) motor is provided to reduce a cogging torque and improve an initial starting performance by arraying an interval between a horizontal junction width and a vertical junction width, asymmetrically. CONSTITUTION: A brushless DC motor is formed with four separative C type permanent magnets(2), a rotator(5), a stator core(1), and a yoke(4). The C type permanent magnets(2) are loaded on the rotator(5). The stator core(1) is formed by combining 9 slots(6). A coil(3) is wound around the stator core(1). The C type permanent magnets(2) are covered by the yoke(4). A horizontal junction width and a vertical junction width of the separative C typed permanent magnet(2) is asymmetrically arrayed among the separative C type permanent magnets(2) and the slots(6) of the stator core(1) in order to reduce a cogging torque generated from a magnetic unbalance. The horizontal junction width and the vertical junction width are asymmetrically arrayed as much as 150 percents.

    Abstract: PURPOSE: A non contact type position sensor is provided to reduce manufacturing costs by simplifying a structure of the non contact type position sensor. CONSTITUTION: A non contact type position sensor includes a housing(2), a rotation shaft(4), a core member(3), a permanence magnet(6), a stopper member(5), a spacer(8), an under cover(7),and an upper cover(9). The housing(2) has a cylinder type. The housing(2) has a first nesting part(22) formed at a bottom surface of the inner side of the housing(2). The housing(2) has a second nesting part(24) formed at an upper part of the housing(2). The housing(2) has an opened upper end. The rotation shaft(4) perforates through the first nesting part(22) and the second nesting part(24) of the housing(2). The permanence magnet(6) is positioned between the rotation shaft(4) and a groove(36) formed at the center of the core member(3).
