The deep-well pumps are practically and widely used to pump water up
from wells. These pumps are driven by squirrel-cage induction motors
where the pump is directly connected with the induction motor it drives.
They form a pump-motor set or a deep
-well set.
Economioally, the cost of digging a well proportionates with the diameter
of the hole opening.
This diameter is related to the deep-well set dimensions. Whenever the
dimensions of the deep-well set are small, the cost of digging a hole will
be notably less.
From here, in this research we shall test the possibility of desiging a
deep-well induction motor with a voltage of f =150 Hz frequency in a
small size. and in trifold speed of the induction motor which has same
power and functions as the motor with a voltage of f = 50 Hz frequency
and where the essential parameters of the motor aren’t worse than the
motor with f = 50 Hz Frequency.
