ニツト。[Claims for Utility Model Registration] A spindle outer cylinder having a hollow hole extending in the axial direction, the spindle outer cylinder being rotatably inserted into the hollow hole, and having spiral grooves formed at a predetermined pitch on its outer peripheral surface. a cylindrical stator attached to a hollow hole in the spindle outer cylinder; and a sleeve attached to the spindle shaft to cover the helical groove and form a helical passage for coolant circulation. a cylindrical rotor fixed to the sleeve facing the stator; a cylindrical rotor attached to the spindle shaft in axial alignment with the sleeve, communicating with the discharge end of the spiral passage and radially outwardly extending from the rotor; a fixing member having a discharge passage extending in the spiral direction, the rotor is cooled by circulating a cooling liquid in the spiral passage, and the cooling liquid that cools the rotor absorbs centrifugal force due to rotation of the spindle shaft. 1. A spindle unit with a built-in motor, characterized in that the fixed member is discharged from the discharge path by using the fixed member.
