Abstract
In a rotating electrical machine configured with a rotor and stator, a lubricant supply portion is configured to supply a lubricant from within. A communication passage is provided in either the rotor support member or the sensor rotor, and is configured so as to provide a passage from a first space, which extends radially outward from the axial first direction side of the sensor rotor and is formed between the support wall and the rotor support member, with a second space, which is formed between the sensor rotor and the rotor support member. The case of the machine has a support wall extending at least in a radial direction to an axial first direction side, which is one side in an axial direction of the rotating electrical machine, and after lubricating the bearing, the lubricant is discharged from the second space to the first space through the communication passage.
