Embodiment

[0050] First of all, for the structure of the rotating electrical machine involved in the embodiment, use figure 1 Be explained. figure 1 It is a longitudinal sectional view showing the structure of the rotating electric machine 1 according to the embodiment. In addition, in figure 1 In , in order to make the description easy to understand, a three-dimensional Cartesian coordinate system including a Z-axis whose positive direction is vertically upward is shown. The Cartesian coordinate system is also shown in the other figures used in the following description.

[0051] In addition, in the following, regarding a plurality of constituent elements, there may be cases where only one of the plurality is designated with a reference numeral, and the reference numerals are omitted for the other components. In this case, it is assumed that the structures of the respective components are the same.

[0052] Such as figure 1 As shown, the rotating electric machine 1 according to the...

Abstract

A rotor (6) of a rotating electric machine (1), the rotating electric machine (1), and an end face member (63) of the rotor (6) are structured such that a rotor core (61) formed by stacking plates, a shaft (62) which is a rotating shaft, and an end ring (63) which is an end face member are provided. The shaft (62) extends through the rotor core (61). The end ring (63) includes a press-fitting portion (63a) to which the shaft (62) is press-fitted, and is attached, by means of the press-fitting portion (63a), to an end face of the rotor core (61) from which the shaft (62) projects.

Description

technical field [0001] The present invention relates to a rotor of a rotary electric machine, a rotary electric machine, and an end face part of the rotor. Background technique [0002] Conventionally, rotors used in rotating electric machines such as electric motors and generators are known. The rotor includes: a rotor core formed by laminating thin-plate magnetic steel materials in a cylindrical shape; and a rotating shaft penetrating the rotor core and fixed thereto. [0003] Furthermore, an annular end ring is attached to the end surface of the rotor core (for example, refer to Patent Document 1). The end rings (hereinafter, sometimes referred to as “end face members”) play a role of securing the rigidity of the rotor core, and the like. [0004] In addition, the end face parts are generally fixed to the rotor core by screws or tapered pins. [0005] Patent Document 1: Japanese Patent Application Laid-Open No. 2-307340 [0006] However, when assembling a conventional...
