Rotating electrical machine system

Abstract

To provide a rotary electric machine system which can accurately detect a rotation parameter of a rotary shaft and also allows easy maintenance of a rotation parameter detector.SOLUTION: A rotary electric machine system 10 comprises: a rotary electric machine 12; a housing 14 for housing the rotary electric machine 12; and a rotation parameter detector 140 for detecting a rotation parameter of a rotary shaft 40 which is a constituent of the rotary electric machine. The rotary shaft 40 has a first end and a second end, and a first bearing 92 and a second bearing 94 are provided between the housing 14 and the first end, and between the housing and the second end, respectively. The first end has a protruding tip 104 which passes through the first bearing 92 so as to protrude to the outside of the housing 14. The rotation parameter detector is provided on the protruding tip.SELECTED DRAWING: Figure 3
