PROBLEM TO BE SOLVED: To provide a rotary electric machine in which a mechanical stress onto a control part is suppressed while fastening two frame ends which hold a stator therebetween, by using through-bolts.SOLUTION: A rotary electric machine 1 is a power source of an electrically-driven power steering device attached to a reduction gear or the like and includes: a stator 30; a rotor 20; a front frame 50 that is disposed at an attachment side; a rear frame 60 holding the stator 30 with the front frame 50; a control part 80 that is mounted on the rear frame 60 for controlling electrification to a coil 32; and a plurality of through-bolts 70 which are inserted into through-holes 522 on the front frame 50 and threaded into the rear frame 60. Therefore, the through-bolts 70 can be disposed radially near the stator 30 without being restricted by a mounting space of the control part 80. Thus, an axial force of the through-bolts 70 can be effectively transmitted to the stator 30, and the mechanical stress onto the control part 80 can be suppressed.SELECTED DRAWING: Figure 1 |
