<p><P>PROBLEM TO BE SOLVED: To provide a permanent magnet type rotary electric machine in which the assembling of a rotor to a rotary shaft can be easily performed, and the assembly man-hour can be decreased, and of which the efficiency is improved by improving positional accuracy of a permanent magnet. <P>SOLUTION: A permanent magnet type rotary electric machine 2 includes a rotor 5 having a permanent magnet 62, and a stator 4. The rotor 5 includes: a magnet unit 6 which is equipped with a cylindrical shaft adapter 61 with the inner peripheral surface 611 as the rotary shaft fitting surface and the permanent magnet 62 mounted rotatably integrally together with the shaft adapter 61 along the outer periphery of the shaft adapter 61; and a magnet cover 7 mountable on the outer periphery of the magnet unit 6. On the inner peripheral surface 611 of the shaft adapter 61, a first groove 616 recessed more than the rotary shaft fitting surface is formed which continues from one end surface 618 in the shaft direction of the shaft adapter 61 to the other end surface 619. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
