1. A rotary electric machine system comprising:
a rotary electric machine that includes a rotor including a rotating shaft, and a stator including an electromagnetic coil;
a housing configured to house the rotary electric machine;
a combinative rotation parameter detector configured to detect a rotation parameter of the rotating shaft; and
wherein
the rotating shaft includes a first end portion and a second end portion, and by disposing a first bearing between the housing and the first end portion, and disposing a second bearing between the housing and the second end portion, the rotating shaft is rotatably supported in the housing via the first bearing and the second bearing,
the first end portion includes a protruding tip that protrudes out of the housing through the first bearing, and
the rotary electric machine system further comprises
a detector holding member that is separate from the housing and is detachably attached to the housing, and
a connector,
the combinative rotation parameter detector includes
a first element that is provided at the protruding tip, and
a second element that is provided at the detector holding member and is electrically connected with the connector,
when the detector holding member is detached from the housing, the first bearing is located between the housing and the first end portion,
the detector holding member includes
an opening at which part of the protruding tip is located when the detector holding member is attached to the housing, and
a hole that holds the connector,
part of the connector held by the detector holding member is located, together with another part of the protruding tip, in an internal space formed by the housing and the detector holding member,
the rotary electric machine system includes a cover that is detachably attached to the detector holding member and closes the opening, and
the connector and the second element of the combinative rotation parameter detector remain held by the detector holding member when the cover is detached from the detector holding member.
