Abstract
The present invention provides a rotor for a synchronous rotary machine, having a rotor core (23) provided in its outer circumference with recesses (26), and permanent magnets (25) each fitted radially in each recess (26) so that its lower surface (25b) will be seated on the bottom surface of the recess (26). Each permanent magnet (25) and each recess (26) are formed so that gaps are formed between the inclined side surfaces (27a, 27b) of the permanent magnet (25) and the corresponding inclined side surfaces (26b, 26c) of the recess (26), and an adhesive filling up the gaps is hardened to form wedging layers (30) capable of restraining the permanent magnet (25) from being separated from the surface of the rotor core (23) by forces acting on the permanent magnet (25) to separate the permanent magnet (25) from the surface of the rotor core (23).
