ENERGY SAVINGS FOR
AC INDUCTION MOTORS |
When fitted to almost any AC
Induction motor Powerboss can produce energy savings of between 10 and 30%,
saving industry millions of pounds in wasted energy. The payback is usually
less than 2 years.

Almost 70% of all
industrial electricity is consumed by electric
motors. |

The humble AC
Induction motor can consume electricity worth almost twenty times its initial
capital cost in ONE YEAR !
Intelligent Energy Savings When a motor is
operating under less than full load a large amount of energy is being wasted.
Both NASA and the British Energy Efficiency Office have stated "in typical
applications, levels of utilisation are approximately 50% with power losses
estimated to be between 40% and 80% of the motor full load rating".
Although they play a vital role in modern life in the production of almost all
products, industry pays dearly for these inefficiencies. POWERBOSS can recover
these losses, reduce costs and thus increase profits!
Powerboss utilises a powerful
micro-controller, which continuously monitors motor efficiency and
ensures the right amount of power is used to complete the job of work. Even
slight changes in demand will be recognised. Powerboss responds immediately by
matching the input power exactly as the load changes thus saving energy!
Powerboss is available from 1.5kW to 450kW
Soft
Start and Soft Stop When
starting, an AC Induction motor develops more torque than is required at full
speed. This stress is transferred to the mechanical transmission system
resulting in excessive wear and premature failure of chains, belts, gears,
mechanical seals, etc. Additionally, rapid acceleration also has a massive
impact on electricity supply charges with high inrush currents drawing 6
9 times the normal run current. The use of Star Delta only provides a partial
solution to the problem. Should the motor slow down during the transition
period the high peaks are repeated and can even exceed direct on line current.
Powerboss provides a reliable and economical solution to these problems by
delivering a controlled release of power to the motor, thereby providing
smooth, stepless acceleration and deceleration. Motor life can be extended as
damage to windings and bearings is reduced.

Soft Start & Soft Stop is built into 3 phase
Powerboss units, providing controlled starting and stopping with a selection of
ramp times and current limit settings to suit all applications.
- Less mechanical stress .
- Improved power factor.
- Lower maximum demand.
- Less mechanical maintenance.
Soft Start and Soft Stop is especially useful
with pumping fluids where torque transients often cause water hammer effects,
and in some instances, failure to gradually slow the fluid down before
stopping, can cause the kinetic energy to rupture pipes and couplings.
