レームレス回転電機。[Claims for Utility Model Registration] (1) In a frameless rotating electrical machine in which both sides of a stator core forming a stator are clamped and fixed by end plates, and the outer circumferential surface of the stator is an outer covering, the stator A substantially polygonal cut portion is provided on the outer peripheral surface of the core over its entire length, and a space is provided in the stator outer cover and covered with a protective cover, and the space is provided at the end of the rotor shaft for cooling air from a cooling fan. A frameless rotating electric machine characterized by having a passageway formed therein. (2) The substantially polygonal cut portion provided on the outer circumferential surface of the stator core is formed by laminating magnetic plates constituting the stator core by skewing them in the axial direction. The frameless rotating electric machine described. (3) In a frameless rotating electric machine in which both sides of a stator core forming a stator are clamped and fixed between end plates and the outer circumferential surface of the stator is an outer covering, the outer circumferential surface of the stator core has a substantially polygonal shape. 3. The frameless rotating electrical machine according to claim 1, wherein a cut portion is provided over the entire length of the frameless rotating electrical machine, and a through bolt for fixing the end plate is provided through the cut portion at a position opposite to the cut portion.
