ABSTRACT:
A stator for magnet-type rotating machines comprises projections formed in the inner circumferential surface of a fixed frame in the circumferential direction at a predetermined distance. Position determining pieces, each having elasticity and engaging parts, are fitted to the projections. Permanent magnets are secured between the position determining pieces in such a manner that the raised portions of the position determining pieces are in contact with end surfaces extending in the radial direction of the permanent magnets and the engaging parts are in contact with end surfaces in the circumferential direction of the permanent magnets to effect determination of position of the same.
