Abstract
A magnet holding member capable of increasing the rotating speed and improving or maintaining reliability of a rotating electrical machine, a rotor having the magnet holding member, a rotating electrical machine having the rotor, and a machine tool having the rotating electrical machine. When one section between one axial end and another axial end of the rotor is referred to as one traverse, the holding member has a cylindrical shape formed by spirally winding a fiber bundle, which is unbroken over at least one traverse, on the outer periphery of the rotor, from one axial end to the other axial end. The holding member is constituted by an FRP having a resin as a matrix, and a terminal treatment by using reactive curable resin is carried out on at least one of a winding start end and a winding terminal end of the fiber bundle.
