Abstract:
1. A rotary electrical apparatus comprising: a housing; a stator fixed within the housing and including a center axis being inclined by a predetermined angle relative to a horizontal direction in a case where the housing is fixed to a mounting member; a rotor accommodated within the housing and provided to face the stator in a radial direction of the stator, the rotor being rotatable relative to the stator at the center axis; and an oil stored at a lower side within the housing relative to the center axis of the stator and the rotor and functioning as at least one of a cooling oil, a lubricating oil, and an operating oil within the housing; the housing including an oil inlet port allowing the oil to be supplied to the housing and an oil discharge port allowing the oil to be discharged to an outside of the housing once a predetermined amount of the oil is stored within the housing, the oil discharge port being displaced from a first oil passage on which the oil supplied from the oil inlet port moves downward along an inner peripheral wall surface of the housing in a state where the housing is held so that the center axis of the stator is arranged to be horizontal.
