Document Type and Number:
Japanese Patent JP6674545
Kind Code:
B2
Abstract:
Provided is a motor-integrated fluid machine that has improved performance and reliability by efficiently cooling a fluid machine body and a motor without increasing an installation space. The present invention is characterized by being provided with: a fluid machine unit that compresses or expands a fluid; a motor unit that has a drive shaft connected to the fluid machine unit; and a cooling fan that cools the motor unit and the fluid machine unit by sucking cooling air from the motor unit side and that is connected to the drive shaft at the side opposed to that connected to the fluid machine unit, wherein between the motor unit and the cooling fan, the minimum sectional area of a cooling air passage from the outside in the radial direction toward the drive shaft is larger than that of a cooling air passage from the motor unit side toward the cooling fan.
