METHOD FOR COOLING SINGLE-SIDE ELECTROMOTOR

摘要

PURPOSE: A method is provided to directly cool an armature coil part through the use of a cooled air in a single-side linear electromotor having a first frame in which a permanence magnet part is assembled, and a second frame in which the armature coil part is assembled. CONSTITUTION: A step involves providing a first frame(11) in which a permanence magnet part(12) is assembled in a plane. A step involves providing a second frame(21) in which the armature coil part(22) is assembled at its inside so that it is in a facing relationship with the permanence magnet part(12) assembled on the plane of the first frame(11) at a predetermined interval. A step involves forming a first air circular path(24) and a second air circular path(25) on horizontal and vertical surfaces of the second frame(21), circulating the cooled air through the first air circular path(24), thereby cooling heat transmitted from the armature coil part(22) to the horizontal surface of the second frame(21). A step involves assembling a nozzle with one end of the second air circular path(25), directly sprinkling the cooled air to the armature coil part(22) for the cooling thereof.
