  • Electric motor having a communication passage
    Patent number: 9660506
    Abstract: An electric motor includes a housing, a rotor, a stator, a storage tank, and a communication passage. The stator has a stator core provided coaxially with the rotor to surround the rotor. The storage tank is provided at a lower portion of the housing to store lubricating oil and divided by the stator core into a first storage tank and a second storage tank. The communication passage is provided to communicate the first storage tank with the second storage tank. The communication passage, as seen in an axial direction, extends above an oil level of the lubricating oil stored in the first storage tank and the second storage tank such that an air flows between an upper portion of the first storage tank and an upper portion of the second storage tank.
