Beschreibung
Zusammenfassung:	An electric motor includes a rotor having a rotary shaft rotating around a vertically extending axis and a rotor core fixed to an outer peripheral surface of the rotary shaft, a stator surrounding the rotor core from an outer peripheral side, a lower bottom portion as a partition wall partitioning a first space where the rotor and the stator are disposed and a lubricating oil is supplied from an outside, a storage portion configured to store the lubricating oil supplied into the first space, a brake mechanism as a drive unit discharging the lubricating oil inside the storage portion into the first space, and sliding portions into each of which the lubricating oil discharged from the inside of the storage portion is introduced.
