NUSCO feels a great interest in protecting limited earth global resources.
We are trying to drive our servo control system as efficiently as possible in terms of energy consume, and we can reduce the energy consume and realize a small contribution to global environment. We have below three earth-friendly technology.
We think to protect the global environment is the mission of industrial company like us and we shall make every eﬀ orts to make our products more eﬃ cient in terms of energy saving.
In our servo control system which accelerates and decelerates machines, when motor accelerates the energy is consumed but when motor decelerates the regenerative energy comes up.
The regenerative energy is wasted by heat radiation through regenerative resistor in normal drive system.
Our condenser bank system accumulates the regenerative energy in the condenser bank and reuse its energy when necessary.
This is not only earth-friendly technology but also cost saving for users.
On the assumption that 110kw motor operates 8hrs/day x 250days/year with mechanical loss 25%,
Regenerative resistor system; 123,750kwh= CO2 emission 49.5ton
Condenser bank system; 49,500kwh= CO2 emission 19.8ton
Thus by comparison the condenser bank system saves 60% energy consumption and reduces about 30ton of CO2 emission per year.
