Rotary electric machine and manufacture thereof

Abstract

Abstract PURPOSE:To fix a frame and brackets highly precisely before the installation of a rotor by providing a hole, through which the rotor can pass, in the brackets which support a rotor shaft. CONSTITUTION:A bracket 3-1 has a hole 11-1 which is larger than the inner diameter of stator 6 and through which the rotor 7 can pass. A bracket 3-2 has a hole 11-2 whose diameter is smaller than the inner diameter of the stator 6. A supporting member 10 such as a pin, a bolt, or the like supports and fixes said brackets 3-1 and 3-2 to the frame 1. In this constitution, since the rotor 7 can be inserted and arranged after the brackets 3-1 and 3-2 have been fixed to the frame 1, the fixing work can be accomplihed highly precisely before the installation of the rotor. Therefore, the gap between the rotor and the stator can be made small and uniform, and the large output can be obtained.
