a result, there has been a constant vigil, by the end users, to
find out a system, to reduce the energy cost. However the use of
modern machinery to produce high quality product, at low costs,
results in an increased power consumption.
In Spinning Industry, there is tremendous pressure, to reduce the
cost of production, since, the margin of profit is very minimum.
The major factors other than raw material are labour and power.
The cost of power is very much on the higher side and is increasing
in the course of time.
One area, where the reduction of power consumption is arrived at,
is the case of a pneumafil motor of a ring frame, which is running
at a constant speed to maintain a constant suction pressure, irrespective
of the number of breakages. The speed of the motor is fixed, such
that, sufficient pressure is maintained for maximum number of breakages,
that one can exxpect under bad working conditions. But, during regular
operation,when the breakage level is low, the pressure is much higher
