An enclosed-configuration electrically powered compressor has an electric motor
with a segment-type stator coil that is directly cooled by a flow of refrigerant
from an intake aperture in the casing, directed onto one or both of the coil end
portions of the stator coil. Each coil segment is formed of a U-shaped conductor
having rectangular cross-section, with each coil end portion having regular spaces
formed between the conductors such as to present low resistance to the flow of
refrigerant, with the refrigerant also flowing through the rotor/stator air gap
of the motor.
