Hermetically Sealed Type
A Hermetically Sealed Type motor utilizes
windings of standard construction and
insulation thickness. The windings are
encased and Hermetically Sealed within the
external shell casing on the outside and an
internal tube or liner inside the bore. The
Hermetically Sealed enclosure eliminates the
possibility of water leakage into the winding
the liquid medium circulates between the
rotor and stator liner providing lubrication
and cooling to the bearings.

Wet Winding Type
A Wet Winding Type motor is one in which
the motor windings are in direct contact
with a liquid medium. The medium is clean,
clear water. A pressure balancing system
prevents exchange of the motor liquid medium
and well water due to thermal expansion
and contraction when the motor is
operating. The liquid medium fills the inside
of the motor and surrounds both the stator
windings and the rotor. A completely water
proof insulation is used on the magnet wire
used for the stator windings. The liquid
medium inside the motor air gap and coils
acts as a heat transfer device by circulating
through the windings and transferring
heat to the external casing. Dissipation of
this heat occurs as the well water flows at a
required velocity over the external case. As is
the case in all submersible type motors, the
internal liquid medium is also used for bearing
lubrication. |
