ROTATING ELECTRICAL MACHINE

摘要

<P>PROBLEM TO BE SOLVED: To provide a rotating electrical machine which can prevent movement of a permanent magnet installed between claw magnetic poles in an axial direction during an operation of the rotary electrical machine. Ž<P>SOLUTION: The rotating electrical machine includes a stator 5 and a rotator 2 supported rotatably on an inner periphery of the stator. The rotator includes a pair of claw magnetic poles 6 and 7 which are oppositely arranged and to which cylindrical field winding wires are wound in center parts, the permanent magnet 9 installed between the claw magnetic poles and a holder 8 holding the permanent magnet in a prescribed position. The holder 8 is pushed to sides of the claw magnetic poles by elastic force operating on a rotation direction of the rotating electrical machine so as to hold the permanent magnet between the claw magnetic poles.
