PURPOSE: A slotless coil winding method is provided to prevent the occurrence of a force which disturbs the rotation in a rotary unit by forming a bobbin using an insulation material. CONSTITUTION: A plurality of coil winding protrusion units(230) winds a coil according to the outer circumference surface of a body unit. A fixed protrusion unit(240) is projected from both sides of the coil winding protrusion unit. The coil is winded at the outer circumference surface of a bobbin. The coil is winded according to the length direction of the bobbin. The coil is winded from a coil winding protrusion unit to another coil winding protrusion unit. Other coil is winded form the winding protrusion unit to other coil winding protrusion unit formed in the bobbin.
