ELECTRIC MOTOR, ROTARY DRIVE SYSTEM, AND HYDRAULIC SHOVEL
Provided is an electric motor that comprises: a rotor comprising a rotating shaft (40) that rotates around an axis (O) extending vertically, and a rotor core fixed to the outer circumferential surfaceof the rotating shaft (40); a stator surrounding the rotor core from the outer circumferential side; a lower base section (27) in which the rotor and the stator are arranged and that serves as a partition for demarcating a first space to which lubricating oil is supplied from the exterior; a storage section (180) capable of storing lubricating oil supplied into the first space (R1); a brake mechanism (120) serving as a drive section for discharging lubricating oil from within the storage section (180) into the first space (R1); and sliding sections into each of which lubricating oil discharged from within the storage section (180) is introduced.
电动机具有：转子，其具有绕沿上下方向延伸的轴线(O)旋转的旋转轴(40)、及固定于该旋转轴(40)的外周面的转子铁心；定子，其从外周侧包围该转子铁心；作为隔壁的下底部(27)，其划分出供转子及定子配置并且被从外部供给润滑油的第一空间；储存部(180)，其能够储存向第一空间(R1)内供给的润滑油；作为驱动部的制动机构(120)，其将储存部(180)内的润滑油向第一空间(R1)内排出；以及滑动部，其分别导入从储存部(180)内排出的润滑油。
