Problems solved by technology

[0019] However, there is a problem in this case in that although there is no guide at the time of lamination, magnet holes are used, but there are many guide parts, and the equipment such as jigs is complicated.
[0031] As can be seen from the above points, it has been difficult in the past to facilitate the manufacture of rotors for permanent magnet type rotating electrical machines.

Abstract

The present invention discloses a rotor of permanent magnet type rotary electric machine and mfg. method thereof where the permanent magnets 3 are inserted in the magnet holes 2 of the rotor iron core 1. After that, at least a part of each magnet hole 2 of the rotor iron core 1 is transformed, and the permanent magnets 3 are fixed to the magnet holes 2. Therefore, a rotor can be easily manufactured.

Description

technical field [0001] The present invention relates to a method of manufacturing a rotor of a permanent magnet type rotating electrical machine comprising a rotor core and a permanent magnet, and the rotor of a permanent magnet type rotating electrical machine manufactured by the method, and particularly relates to a permanent magnet capable of easily manufacturing the rotor A method of manufacturing a rotor of a permanent magnet type rotating electrical machine and a rotor of a permanent magnet type rotating electrical machine manufactured by the method. Background technique [0002] In the past, permanent magnet type rotating electrical machines generally consisted of a stator and a rotor, and the rotor rotated inside the stator via a gap. [0003] The stator accommodates armature coils in slots provided in the stator core. [0004] Rotor such as Figure 1A and 1B As shown in the side sectional view and the radial sectional view respectively, no coils for forming a magn...
